What Are Cenotes? A Local Guide to Tulum’s Sacred Freshwater World
Geology, Maya history, conservation, local economy, family memory, and how to visit cenotes with respect.
The first time you lower yourself into a cenote, something changes.
The air feels cooler. The sound becomes softer. The jungle seems to pause around you. Below, the water is so clear it almost does not look like water at all — pale blue turning into dark blue, sunlight bending through the surface, stalactites hanging from the ceiling like frozen time.
You are not in the ocean.
You are not in a swimming pool.
You are inside the earth.
That feeling is difficult to explain to someone who has never experienced it. But it has something to do with understanding that cenotes are not just beautiful places to swim, snorkel, or dive. They are geological windows, freshwater systems, sacred places, local gathering spaces, and living environments that the Yucatán Peninsula has depended on for thousands of years.
Today, cenotes are famous around the world. People travel to Tulum to swim in them, photograph them, snorkel through them, and dive into their cavern systems. But before cenotes became international attractions, they were part of daily life for local families.
For many of us who grew up here, cenotes were not always “tours.” They were weekend afternoons. They were family places. They were where we would go to swim, bring food, prepare ceviche, and spend the day close to the water.
That has changed. Tourism, entrance fees, infrastructure, social media, and the growth of Tulum have transformed the way people visit cenotes. Some of that change has created opportunity for local families, ejidos, landowners, guides, drivers, restaurants, and dive centers. But it has also created pressure on fragile places that need respect and care.
This guide is our attempt to explain what cenotes really are — before you swim, snorkel, or dive in one.
What Is a Cenote?
In the simplest terms, a cenote is a natural sinkhole or opening in limestone that exposes the freshwater of the underground aquifer below.
The word “cenote” comes from the Maya word ts’ono’ot or dzonot, often translated as a place with accessible groundwater. But the simple definition does not fully capture what a cenote is.
A cenote is not just a hole with water.
It is an entrance into the freshwater heart of the Yucatán Peninsula.
The Yucatán Peninsula has very few surface rivers. Instead of flowing across the land, rainwater filters down through porous limestone. Over thousands of years, this water slowly dissolves the rock, creates underground passages, fills cave systems, and forms chambers beneath the jungle floor.
When the roof of one of those underground chambers collapses, fully or partially, the water below becomes visible. That opening is what we call a cenote.
Some cenotes are wide open pools under the sky. Some are semi-open, with light entering through a hole in the ceiling. Others feel like underground cathedrals, with stalactites, stalagmites, columns, and dark passages leading into the earth.
Cenotes are usually described in four main types:
Types of Cenotes Near Tulum
Not all cenotes are the same. When diving tulum cenotes, you can find open cenotes, semi-open cenotes, cavern cenotes, and deeper cave systems. Each one offers a different kind of experience depending on your certification level, comfort, and the type of dive you want to do.
| Type of Cenote | What It Means | Best For | Example Near Tulum |
|---|---|---|---|
| Open Cenotes | Fully open to the sky and often surrounded by jungle or mangroves. | Beginners, Discover Scuba Diving, relaxed freshwater dives, and snorkeling. | Casa Cenote, Cenote Naval, Yaxchen Cenote |
| Semi-Open Cenotes | A mix of open-water areas and covered sections, often with beautiful natural light. | Certified divers looking for a calm introduction to cavern-style diving. | Carwash, Dos Ojos, Cenote Nohoch |
| Cavern Cenotes | Partially enclosed underwater environments where divers stay within the natural light zone. | Open Water certified divers and above, guided by a trained cenote guide. | Cenote Teresita, Nicte Ha, Dreamgate |
| Cave Systems | Fully overhead cave passages beyond the natural light zone. | Certified cave divers only. This requires specific cave diving training. | Sac Actun, Ox Bel Ha and other cave systems in the Riviera Maya |

This difference matters, especially for divers. A peaceful-looking cenote at the surface may be connected to a complex cave system below.
How Cenotes Form: Limestone, Rain, and Time
Before the Yucatán became the land we know today, much of this region was covered by shallow seas. Over millions of years, calcium-rich remains from marine organisms — including corals, shells, and microscopic sea life — accumulated and slowly formed thick layers of limestone.
That limestone became the foundation of the peninsula.
Because limestone is porous and dissolves slowly in contact with slightly acidic rainwater, the Yucatán became a perfect landscape for underground caves, rivers, and cenotes to form.
As rain falls on the jungle, it absorbs carbon dioxide from the air and soil, becoming mildly acidic. That water filters through cracks and pores in the limestone. Little by little, over thousands and thousands of years, it dissolves the rock and opens small spaces underground.
Those spaces grow into tunnels.
Tunnels grow into chambers.
Chambers fill with freshwater.
And sometimes, the ceiling collapses.
That collapse creates a cenote.
This kind of landscape is called a karst system — a landscape shaped by the dissolution of soluble rock. In the Yucatán, this karst system is enormous. It is the reason the peninsula has so many cenotes, underground rivers, flooded caves, and crystal-clear freshwater windows hidden beneath the jungle.
It also explains why cenote water is so clear.
Rainwater filters slowly through layers of limestone before reaching the underground aquifer. The rock acts like a natural filter, removing much of the sediment that would normally cloud the water. Many cenotes have little current, little suspended material, and very low wave action compared with the ocean.
That is why, in some cenotes, visibility can feel almost unreal. You can look down and see tree roots, rock formations, cave entrances, and divers below you as if they were floating in air.
Were Cenotes Formed by the Asteroid?
This is one of the most common questions people ask about cenotes in Mexico.
The short answer is: not exactly.
Most cenotes were formed through the slow process of limestone dissolving, underground caves forming, and sections of cave ceilings collapsing. That is the main geological process behind cenotes across the Yucatán Peninsula.
But the asteroid is still part of the story.
Around 66 million years ago, a massive asteroid struck what is now the northern Yucatán Peninsula. This impact created the Chicxulub crater and is connected to the mass extinction event that ended the age of the non-avian dinosaurs.
Today, the crater is buried. You cannot stand on the surface and see a giant hole. But its presence is still visible in the landscape.
In northwestern Yucatán, many cenotes form a wide circular arc known as the Ring of Cenotes. This ring follows part of the buried rim of the Chicxulub crater, showing how an ancient cosmic impact shaped the geology and water systems of the region.
So, not every cenote was created directly by the asteroid. But the Chicxulub impact helped shape part of the geological structure where many cenotes later formed.
When you enter a cenote, you are entering a place shaped by rainwater, limestone, time, collapse, and, in some parts of the peninsula, the deep geological memory of an asteroid impact.
Cenotes and the Maya: Water, Survival, and the Underworld
For the ancient Maya, cenotes were not curiosities. They were life itself.
In a peninsula with few surface rivers, cenotes provided access to freshwater. They influenced where people could live, where communities could grow, and where cities could be built. Water was not simply convenient — it was survival.
For the Maya, cenotes served several important purposes.
They were sources of drinking water in a land with very few rivers. They helped determine where communities could settle. They supported agriculture, daily life, and travel routes through the peninsula. But they were also ceremonial spaces connected to rain, fertility, life, death, and the underworld.
In Maya cosmology, cenotes were deeply sacred. They were understood as entrances to the underworld, often connected with Xibalba, the realm beneath the surface of the world. The edge of a cenote was not just a place where land met water. It was a threshold between worlds.
Ceremonies were held near cenotes. Offerings were made. In some sacred cenotes, archaeologists have found pottery, jade, shells, bones, and human remains, showing that these places carried deep spiritual importance.
Offerings were part of a spiritual relationship with the gods, especially deities connected with rain and water, such as Chaac.
This is one reason we believe cenotes should be approached with respect. Even if you visit as a traveler, swimmer, snorkeler, or diver, you are entering a place that has carried meaning for thousands of years.
A cenote is not only beautiful.
It has memory.
The Invisible River Under the Peninsula
One of the most important things to understand about cenotes is that they are not isolated pools.
They are openings into the Yucatán aquifer — the underground freshwater system that supports communities, wildlife, mangroves, cenotes, and coastal ecosystems across the peninsula.
Rain falls on the jungle. It filters through limestone. It moves through cracks, tunnels, caves, and underground passages. This water eventually emerges through cenotes, lagoons, mangroves, coastal springs, and sometimes directly into the Caribbean Sea.
In many places, there is no visible river at the surface. But underground, the water is moving.
This is why we sometimes describe the aquifer as an invisible river beneath our feet.
That invisible river supplies communities, ecosystems, mangroves, wildlife, and coastal environments. It is also part of what makes Tulum and the Riviera Maya so special. The cenotes, the jungle, the mangroves, and the reef are not separate worlds. They are connected through water.
At Casa Cenote, also known as Cenote Manatí, you can see this connection very clearly. Casa Cenote is close to the coast and connected to the mangrove and Caribbean system. Its water is brackish, meaning freshwater from the aquifer mixes with saltwater from the sea. You can swim, snorkel, or dive through mangrove roots and feel how the inland freshwater world connects with the ocean.
That connection is one of the reasons Casa Cenote feels so unique. It is not only a cenote. It is a meeting place between the jungle and the sea.
“Dead Water”: A Family Story About Cenotes
In our family, cenotes are not only something we guide today. They are part of the stories we grew up hearing.
When my father was a kid in Tulum, around 12 years old, the grandmothers in town used to warn children not to go swimming in the cenotes. They would say the cenote water was “dead water.”
Of course, as kids often do, my father and his friends did not always listen.
They would escape, hide from the grandmother, and go swimming in the cenotes anyway. That is how many of them learned to swim — not in a pool, not in a swim class, but in the freshwater openings of the jungle.
Years later, talking about those memories with my father, that phrase started to make sense in a different way.
The sea has salt, and saltwater gives you more buoyancy. You float more easily. Cenote water is freshwater. It has no salt, so your body feels heavier and you sink more than you do in the ocean.
Maybe that is what the older people meant when they called it “dead water.” Maybe it was also a way of warning children about places that were deep, quiet, and mysterious. Maybe it was both.
That is the beauty of local stories. They carry fear, wisdom, protection, memory, and sometimes even a little bit of science without explaining it in scientific language.
Today, when we dive cenotes, we understand the physics. We know about freshwater, saltwater, buoyancy, haloclines, depth, and safety rules. But those old stories still matter. They remind us that cenotes were always respected by the people who lived near them — sometimes with love, sometimes with caution, and sometimes with mystery.
What Is a Halocline?
In some cenotes, especially deeper ones or those closer to the coast, freshwater and saltwater exist in layers.
Freshwater is lighter. Saltwater is denser. Because of this difference, they do not always mix evenly. Instead, freshwater can sit above saltwater, creating a boundary layer called a halocline.
For divers, a halocline is one of the most surreal things to experience underwater.
When you swim through it, the water begins to shimmer. Vision becomes distorted. Rocks, divers, and lights appear to bend and blur. It can feel like looking through liquid glass.
This is not dirt or bad visibility. It is physics — light refracting differently as it passes through layers of water with different salinity.
In cenotes like The Pit, the halocline is part of the magic. It reminds you that even in a silent underground chamber, different worlds of water are meeting.
Cenotes and the Reef: More Connected Than Most People Realize
At Mexidivers, we spend our lives between two underwater worlds: the cenotes and the Caribbean reef.
Many visitors think of these as separate experiences. One day you dive in freshwater caverns. Another day you dive on the reef. But in nature, these worlds are connected.
The freshwater moving through underground cave systems travels toward the coast. Along the way, it interacts with mangroves, lagoons, and coastal springs. Eventually, some of that water reaches the Caribbean Sea.
Mangroves help filter water and provide nursery habitat for fish. The reef depends on clean coastal water. The health of the aquifer influences the health of the coastline. What enters the groundwater inland can eventually affect the mangroves and the reef offshore.
This means that cenote conservation is not only about keeping one swimming hole clean.
It is about protecting the water system that connects the jungle, the communities, the coast, and the reef.
For us, this is personal. We dive the cenotes, but we also dive the reef. We see both sides. We understand that the freshwater below the land and the saltwater in front of Tulum Beach are part of the same larger living system.
Why Cenotes Are Fragile
The same thing that makes cenotes magical also makes them vulnerable.
They are open doors into the aquifer.
When sunscreen, oils, soaps, insect repellent, trash, wastewater, or chemicals enter a cenote, they do not simply disappear. They can move into the groundwater system. From there, they may travel through underground passages and affect other cenotes, mangroves, coastal springs, and eventually the sea.
Cenotes are also physically fragile. Stalactites and stalagmites take thousands of years to form. A single careless touch, kick, or broken formation cannot be replaced in a human lifetime. Sediment that is kicked up by poor buoyancy can reduce visibility for other divers and affect the delicate environment inside the cavern.
This is why responsible behavior matters.
Showering before entering is not just a rule.
Avoiding sunscreen is not just a suggestion.
Not touching formations is not just about manners.
It is about understanding that you are entering a living freshwater system.
Before Cenotes Became Famous
Before the big wave of tourism, many cenotes had a very different feeling.
For local families, they were not always commercial places. They were part of weekend life. More than 20 years ago, I remember going to cenotes as a kid with my family. We would go in the afternoon, swim, bring food, prepare ceviche, and spend time together near the water.
It was simple. It was local. It was part of growing up here.
There were no big platforms, no long lines of visitors, no social media photo shoots, and often no formal entrance structure. The cenote was a place to cool down, gather, eat, laugh, swim, and share the day.
Over time, that changed.
As Tulum and the Riviera Maya became known around the world, cenotes became part of the tourism economy. More people wanted to visit them. Roads were improved. Stairs, bathrooms, parking areas, signs, and safety rules were added. Entrance fees became normal. Some cenotes became managed by local families, some by ejidos, some by private landowners, and some by larger groups.
This change has many sides.
On one hand, cenote tourism supports local people. It creates work for landowners, guides, drivers, dive centers, restaurants, maintenance teams, equipment providers, and families who depend on this economy.
On the other hand, cenotes have lost some of the simplicity they once had. Places that were once quiet family spaces are now international destinations. That can bring pressure, crowding, pollution, and a feeling that sacred or local places have become products.
Both things can be true.
Cenote tourism can be a source of livelihood, pride, and opportunity. But it also needs awareness, limits, and respect. We believe the best way forward is not to reject tourism, but to practice it in a way that remembers what these places are — and what they were before they became famous.
Why Cenotes Have Entrance Fees
Many visitors are surprised when they learn that cenotes have entrance fees.
It is worth understanding why.
Most cenotes in the Tulum and Riviera Maya area are located on private land, ejido land, or land managed by local families and communities. Entrance fees help support the people who care for these places and keep them accessible.
Those fees can help pay for:
Land access
Bathrooms and showers
Stairs and platforms
Parking areas
Cleaning and trash management
Staff and local guides
Maintenance
Safety infrastructure
Community and family income
Of course, not every cenote is managed in the same way. Some are small family-run places. Others are larger operations. Some feel very local and simple. Others are more developed and touristic.
But in general, entrance fees are part of the modern reality of visiting cenotes. They reflect how these places have moved from being informal local gathering spots to protected, maintained, and heavily visited natural sites.
As a local dive center, we see these fees as part of the local economy. They help many people make a living from nature-based tourism. At the same time, we believe that economy must stay connected to respect, conservation, and fair treatment of the places and people involved.
Paying to enter a cenote should not feel like paying for a swimming pool.
It should feel like contributing to the care and access of a place that belongs to the land, the water, and the local community around it.
Cenotes in the Age of Social Media
Today, cenotes are some of the most photographed places in Mexico.
You see them on Instagram, TikTok, travel blogs, wedding shoots, yoga retreats, and luxury travel pages. The images are beautiful: blue water, jungle openings, shafts of light, people floating under ancient rock formations.
It is easy to understand why the world fell in love with them.
Cenotes are beautiful, and it is natural to want to remember them.
How to Visit a Cenote Respectfully
Most of the time, respectful cenote behavior is simple. It begins with remembering that you are entering a freshwater system, not a theme park.
Before entering the water:
Shower thoroughly.
Remove sunscreen, body oils, perfumes, lotions, and insect repellent.
Use the bathroom before getting in.
Avoid bringing food or drinks near the water.
Follow the rules of each cenote.
While swimming or snorkeling:
Do not touch formations, walls, stalactites, or stalagmites.
Do not leave trash.
Stay within allowed areas.
Respect quiet spaces.
Listen to local staff and guides.
Avoid standing on fragile rocks or underwater formations.
Do not jump from rocks unless it is clearly allowed and safe.
For divers:
Maintain good buoyancy.
Avoid touching the bottom, ceiling, walls, or formations.
Do not kick up sediment.
Stay close to your guide.
Stay within your certification level.
Never enter a cave system without proper cave diving training.
Respect cavern diving limits and the natural light zone.
A cenote can give you one of the most beautiful experiences of your life. The least we can do is enter with care.
Swimming, Snorkeling, Cavern Diving, and Cave Diving
Cenotes can be experienced in different ways depending on your comfort, training, and interest.
Swimming
Swimming is the simplest way to experience a cenote. Many open or semi-open cenotes are perfect for families, children, and visitors who simply want to cool off and enjoy the water.
No certification is needed. But respect is still important. Shower before entering, avoid sunscreen, follow local rules, and remember that even if you are just swimming, you are still inside a freshwater system.
Snorkeling
Snorkeling allows you to see more of the cenote without scuba equipment. In clear water, you can often see rock formations, fish, roots, cave entrances, and light effects from the surface.
Cenote snorkeling is a beautiful option for non-divers, families, and people who want a calm but meaningful experience. Places like Casa Cenote and Nicte Ha can be especially beautiful for snorkeling.
Cavern Diving
Cavern diving is the experience most certified recreational divers come to Tulum for.
In cavern diving, you enter the overhead environment of a cenote while staying within the natural light zone. This means you are guided through areas where daylight is still visible and where the dive follows specific safety limits.
Many cavern dives are available to Open Water certified divers when guided by a trained professional. Other cenotes, especially deeper ones like The Pit and Angelita, require Advanced certification and more experience.
Cavern diving is where you experience the magic of cenotes fully: the silence, the formations, the light beams, the halocline, and the feeling of floating through the earth.
Cave Diving
Cave diving is completely different.
Cave diving goes beyond the natural light zone into full overhead environments. It requires specialized training, redundant equipment, strict gas planning, guideline procedures, emergency protocols, and a very different mindset from recreational diving.
Cenote cave systems in the Tulum area are complex and beautiful, but they are not places to improvise. Cave diving without proper training is extremely dangerous.
This distinction matters.
Cavern diving with a trained guide can be safe, accessible, and unforgettable for certified divers. Cave diving is a technical discipline that requires its own path of training.
Are Cenotes Dangerous?
Cenotes are generally safe when visitors respect the rules, stay within allowed areas, and go with trained guides when snorkeling or diving.
But like any natural environment, they deserve respect.
A cenote can be deep. The rock edges can be slippery. Some areas may be restricted. Some cenotes connect to overhead cave systems. For divers, the risks increase when someone goes beyond their certification level, ignores gas limits, enters cave zones without training, or loses control of buoyancy.
This is why local guidance matters.
The goal is not to be afraid of cenotes. The goal is to understand them. When you visit the right cenote for your level, listen to the rules, and go with experienced guides, cenotes can be safe, peaceful, and unforgettable.
Why Local Knowledge Matters
Cenotes are not all the same.
The entrance, depth, visibility, flow, crowd level, road conditions, fees, rules, and best time of day can change from one cenote to another. Some are ideal for beginners. Others are better for advanced divers. Some are perfect for snorkeling. Others are not appropriate unless you have the right training.
A local guide understands these differences.
They know how to match the cenote to the person. They know when a place is too crowded, when visibility is not ideal, when a different option would be better, or when conditions require changing the plan.
They also understand the local relationships behind the cenotes — the families, communities, and people who maintain access and make these experiences possible.
At Mexidivers, cenotes are not just products on a website. They are part of the landscape we grew up with, part of our diving life, and part of our local economy. My father and I have seen how these places have changed over time. We have seen them as family spaces, as dive sites, as sacred places, and as sources of work for many people.
When we take guests to a cenote, we are not simply taking them to a location.
We are taking them into a place we know, respect, and love.
Frequently Asked Questions About Cenotes
What is a cenote?
A cenote is a natural opening in limestone that exposes freshwater from the underground aquifer. Cenotes form when limestone dissolves over time and underground cave ceilings collapse, creating access to the water below.
What is a cenote in English?
In English, a cenote is usually described as a natural sinkhole or limestone opening that exposes groundwater. The word comes from the Maya ts’ono’ot or dzonot, referring to a place with accessible water.
What are cenotes in Tulum, Mexico?
Cenotes in Tulum are natural freshwater openings connected to the underground aquifer of the Yucatán Peninsula. Some are open pools, some are semi-open, and others lead into cavern and cave systems used for snorkeling, swimming, and scuba diving.
How were the cenotes in Tulum formed?
Tulum’s cenotes formed through the same karst process found across the Yucatán Peninsula. Rainwater dissolved the limestone bedrock over thousands of years, creating caves and underground rivers. When parts of those cave ceilings collapsed, cenotes opened to the surface.
What created the Mexican cenotes?
Mexican cenotes, especially in the Yucatán Peninsula, were created by the dissolution and collapse of limestone. Rainwater filtered through porous rock, carved underground caves, and exposed freshwater when sections of the cave roofs collapsed.
Were cenotes formed by the asteroid?
Not directly in most cases. Most cenotes formed through karst processes: rainwater dissolved limestone, created underground caves, and eventually some cave ceilings collapsed. However, the Chicxulub asteroid impact helped shape part of the Yucatán’s geology, and the famous Ring of Cenotes follows part of the buried rim of the crater.
Are cenotes freshwater or saltwater?
Most cenotes are primarily freshwater. Some coastal cenotes, like Casa Cenote, are brackish because freshwater from the aquifer mixes with saltwater from the Caribbean. In deeper cenotes, freshwater and saltwater may form separate layers, creating a halocline.
Why is cenote water so clear?
Cenote water filters through limestone before reaching the aquifer. This natural filtration removes much of the sediment found in other bodies of water. Many cenotes also have very little wave action or current, which helps maintain excellent visibility.
Can beginners dive in cenotes?
Yes, some cenote cavern dives are suitable for certified Open Water divers when guided by a trained professional. Cenotes like Casa Cenote, Carwash, and Dos Ojos can be good options depending on the diver’s comfort and conditions. Deeper cenotes like The Pit and Angelita require Advanced certification and more experience.
Do I need to be certified to dive in cenotes?
Yes. For scuba diving in cenotes, you need at least an Open Water certification. For snorkeling or swimming, no diving certification is needed.
What is the difference between cavern diving and cave diving?
Cavern diving stays within the natural light zone and follows recreational diving limits with a trained guide. Cave diving goes beyond natural light into full overhead environments and requires specialized technical cave diving certification.
What were cenotes used for by the Maya?
Cenotes were used by the Maya as freshwater sources, community water access points, and sacred ceremonial spaces. In some cenotes, offerings were made to gods connected with rain, water, fertility, and the underworld.
Why are cenotes important to Maya culture?
Cenotes were essential freshwater sources for Maya communities and also held deep spiritual meaning. They were often seen as entrances to the underworld and used for ceremonies and offerings.
Can I wear sunscreen in a cenote?
It is best to avoid sunscreen, oils, lotions, perfumes, and insect repellent before entering a cenote. These products can dissolve into the water and enter the aquifer. Most cenotes ask visitors to shower before getting in.
Why do cenotes have entrance fees?
Most cenotes are located on private, ejido, family, or community-managed land. Entrance fees help support access, bathrooms, showers, cleaning, staff, platforms, parking, maintenance, safety, and the local families or communities connected to the cenote.
Are cenotes dangerous?
Cenotes are generally safe when visitors respect the rules, stay within allowed areas, and go with trained guides when snorkeling or diving. The risks increase when people jump from unsafe areas, enter restricted cave zones, dive beyond their certification, or ignore local guidance.
What is the Ring of Cenotes?
The Ring of Cenotes is a circular arc of cenotes in northwestern Yucatán that follows part of the buried rim of the Chicxulub crater, the impact structure created by the asteroid that struck the region around 66 million years ago.
What is the best cenote near Tulum?
There is no single best cenote for everyone. Casa Cenote is great for beginners and snorkelers. Dos Ojos is iconic for cavern diving. The Pit and Angelita are unforgettable for advanced divers. The best cenote depends on your level, comfort, and the kind of experience you want.
Visit Cenotes With Respect
Cenotes are one of the greatest natural treasures of the Yucatán Peninsula. They are beautiful, but they are also delicate. They are ancient, but still alive. They are part of Maya history, local memory, the modern tourism economy, and the freshwater system that connects the jungle to the Caribbean Sea.
At Mexidivers, we believe visiting a cenote should be more than just an activity.
It should be an experience of understanding.
Whether you come to swim, snorkel, or dive, we invite you to enter slowly, listen, respect the rules, support the local people who care for these places, and remember that every cenote is more than a destination.
It is water.
It is history.
It is life.
And we are only guests.
