Cavern diving in the Cenotes of Yucatan

Discover the Cenotes of Yucatan Mexico underwater


The Cenotes of Yucatan offers to divers the possibility to experience a unique type of dive: cavern diving in the Cenotes.

Diving in Cenote will give you a hint of what cave diving looks like in case you are yet undecided to become a cave diver or just want to enjoy the experience once.

What is a cenote?

The word “Cenote” comes from the Mayan “dzonot”. Cenotes are sinkholes created by the collapse of the limestone rocks, filled with crystal clear water.

The Yucatan penninsula is covered with Cenotes. They are found almost everywhere, some remain undiscovered deep in the jungle and others are right in the center of cities and villages. Furthermore they can have all sizes and shapes, some have underwater passages, some offer large pools while others are vertical pits. The Maya considered the Cenotes were sacred doors.

Diving in the Cenotes of Yucatan

Diving in the Cenotes is an exciting experience. You will enjoy the best diving conditions you can imagine. The water is crystal clear and the visibility is incredible, there is very little current and the water is warm all year around (25°C/76F). The underwater caves feature lots of speleothems (stalactites, stalagmites, columns, flowstones…) and stunning sunrays penetrating the darkness of the cave through small openings in the ceiling.

What certification is needed to dive in a Cenotes?

To discover the cavern part of the Cenotes on most sites you will only need an Open Water certification or equivalent, good buoyancy skills and a great level of comfort.

And if you want to go further you will need to get cave diving training and your guide can give you all the necessaries informations.

Formations of the Cenotes

These unique formations are due to a sequence of geological and climatic events. Several million years ago, the Yucatan penninsula was submerged by the ocean and arrised during the glaciation period, when the sea level drops.

Cenotes are formed by dissolution of rock creating a void bellow the bedrock  and the subsequent collapse. These collapses occur during periods when the water table is below the ceiling of the void, since the rock ceiling is no longer buoyantly supported by the water.

What are speleothems?

Speleothems are cave formations resulting from mineral deposits. They take various forms, depending on whether the water drips, seeps, condenses, flows, or ponds. The most known speleothems are:
• Stalactites: hanging from the cave ceiling
• Stalagmites: the “ground-up” counterparts of stalactites
• Column: when stalactites and stalagmites meet or when stalactites reach the floor of the cave
• Drapery, curtain or bacon are thin sheets of calcite hanging downward
• Flowstone: covering floor and walls of a cave
• Soda straws: very thin but long stalactites having an elongated cylindrical shape

You will observe all of these mineral formations and many more in cenotes.

What is the halocline?

A halocline is a type of chemocline caused by a strong, vertical salinity gradient within a body of water. Because salinity (along with temperature) affects the density of water, it plays a role in its vertical stratification. In Cenotes, you will discover this very characteristic and fascinating phenomenon of Haloclines. And you will observe it particularly cleary in Tajma Ha Cenote and Eden Cenote.

The phenomenon is very visual and the demarcation between fresh water and salt water is very clear. In the presence of a halocline, when ascending from the salt water layer (below) to the fresh water the diver can have the feeling of floating in air over water.

In which Cenotes can we do cavern diving?

Cavern diving

Here is a list of the most reknown cenotes in the Riviera Maya. There are many more to be discovered and for the most adventurous divers wanting to experience new dive sites consider a trip to the Cenotes Yucatan around Mérida  and add the culture and the culinary experience to your diving.

The Pit

Depth: 40 meters/ 120 feet
Difficulty: Difficult

The Pit is one of the deepest Cenotes of Yucatan (130 meters) and is part of one of the biggest cave system in the world. You will enjoy the amazing light beams going all the way down to the sulfide layer at 30m.

Taj Ma Ha

Depth: 15 meters/ 50feet
Difficulty: Moderate

The Cenote Tajma ha is located 5 km south of Puerto aventuras. A fairly demanding dive due to the multiple depth changes, you will be rewarded by the stunning beauty. You will observe lots of stalactites, stalagmites and fossils, 3 other Cenotes on the way with amazing light effects and come accross the halocline a few times.

Cenote Angelita

Depth: 40 meters/ 120 feet
Difficulty: Difficult

AngelitaThe Cenote Angelita is one of the deepest cenote in the Riviera Maya. It is particularly known for its sulfuide layer looking like an underground river flowing around a small island whith a few trees. Under the cloud, you will experience total darkness. This is an exceptional dive full of sensations and is for experienced divers only.

Cenote Car Wash

Depth: 16 meters/ 50 feet
Difficulty: Easy

Cavern diving course : first steps into the world of cave diving

Aktun Ha better known as Car Wash is located near Tulum. Its name come from the fact that people used to come to this cenote to wash their cars. In summer the open water pool is covered by a thick and dense layer of algae bloom whith very reduced visibility. Below this layer the water is crystal clear with subtle green brightness. You will meet turtles, fish and possibly a small crocodile. And you will enjoy the amazing beauty of the water lilis.

Cenote Chac Mool and Kukulcan

Depth: 14 meters / 50 feet
Difficulty: Easy

Cenote Kukulkan, cavern dive in the winter morning light

The Chac Mool Cavern Line leads you through a large well lit Cavern Zone with very impressive breakdown formations and spectacular views of the jungle from underwater. You will see tree roots growing down into the water along the edge of Main Entrance and dive a hypnotic halocline passage.
Halfway through the dive you can surface in a beautifully decorated air dome before continuing on through a cathedral of speleothems.

Cenote Kukulkan offers in winter one of the most amazing light show you can imagine.

Cenote Eden

Depth: 15 meters/ 50 feet
Difficulty: Easy

The Cenote Eden also known as Ponderosa features beautiful light effects and a wonderful halocline. In the open water pool you will observe many colorful fishes.

Chikin Ha

Depth: 15 meters / 50 feet
Difficulty: Easy

Cenote Chikin Ha - Map of the cavern dive
Cenote Chikin Ha – Map of the cavern dive

Chikin Ha means “Western Water”  it is a very large half moon cenote with crystal clear water.

The permanent guideline begins in the open water of Chikin Ha and traverses over to Cenote Arcoiris (Cenote Rainbow) through a large halocline tunnel. On the way back to Chikin Ha you will see fossils, crystal formations and speleothems.

Dos Ojos

Depth: 9 meters / 30 feet
Difficulty: easy

Dos Ojos is probably one of the most known Cenote dive thanks to the I-max movie “Amazing Caves”. The cenote offers two different dives,  the Barbie Line, a circuit with massive columns and stalactites. The Batcave Line is more like a dark cave as you swim around an air bell with very little light entry. All along you will enjoy the variety of its delicate formations.

Pet Cemetry

Depth: 7 meters / 30 feet
Difficulty: Moderate

As the name suggests, you will see along your dive, at the bottom, some animal skeletons. And above all this is not even the hit of these dives! This cave is amazingly decorated with white speleothems. the nearby surface will offer stunning reflexions of these formations. Just hold your breath and enjoy! And if you need more look between the roots for blind fish 🙂

Dreams Gate

Depth: 7 meters / 30 feet
Difficulty: Average

Dreamgate requires really good buoyancy skills as it is very shallow and has very low ceiling. Very decorated with delicate formations, make sure you dive close to the line to limit the impact of your bubbles or an unfortunate fin kick. We love the place and want to enjoy it for a long time.


Depth: 40 meters / 120 feet
Difficulty: Very difficult

Zapote is one  of the most demanding Cenote dive as it is deep and fairly dark and you will also encounter a sulfide cloud. But most of all it is very rewarding as, out of this cloud, you will face very special formations, in the shape of a bell. Keep in mind that not only they are very surprising but the are still new to science.

Casa Cenote

Depth: 8 meters /  30 feet
Difficulty: Easy

Casa Cenote - Cenote Manati - Tank Ha

Casa Cenote is one of the easiest cenote dive. You will dive directly under the mangroves and get the chance to meet some marine life since the Cenote is directly connected to the ocean. Most of all you will swim across a dense halocline and observe some beautiful lights effects.

Is Cenote diving for Me?

You are planning a dive trip to the Yucatan Penninsula in Mexico? Then you might have come accross some amazing pictures of the beautiful Cenotes. Once stunned by these pictures you probably want to see it with your own eyes and live the experience.

But this question keeps popping up: is Cenote diving for me?

  • What are Cenotes?

Deep Cave diving in the Cenotes of Yucatan, Mexico
Deep Cave diving in the Cenotes of Yucatan, Mexico

Cenotes are sinkholes distributed all over the Yucatan Peninsula. They are the window to the underwater caves and caverns. And they are one of the main dive attraction in the area and one of the top dive destination in the world.

Those caves are highly decorated with stunning formations such as stalagmites and stalactites which makes them very unique.

Your first Cenote diving experience will probably be a cavern tour. You are not required to have a cave diving certification as you will not be technically entering the cave.

  • What is a cavern dive?

A cavern dive is the exploration of a natural overhead environment while remaining within sight of natural light.

When diving in the Cenotes you will always see natural light and have a sight of a direct way out of the cavern. However do not underestimate safety by thinking it is an easy dive. And here are some thoughts to consider before going for a cavern dive.

  • Will I be swimming in tight places?
Gran Cenote - Cavern diving in Tulum
Gran Cenote – Cavern diving

No you won’t!

It is a requirement for all cavern dive in the Cenotes to go through areas where two divers can fit side by side at all time. You will not swim in any tight areas.

Should any problem arrize you will be able to swim side by side with your guide to exit the cavern.

  • Can accidents happen while Cenote diving?

Yes, it can happen…

Your cavern guide should be a qualified divemaster or instructor in teaching status and a certified cave diver. Of course the more experienced the better the guide can react to a bad situation. And the more he/she knows the site, the better he/she can handle the situation.

Cavern diving by the book, is really safe. The conditions are optimal: shallow dives, no current, great visibility, group size limited to 4 divers maximum per guide and all divers should be experienced.

We recommend you to choose carefully your dive operator or guide. And remember the most experienced the guide the better he/she can show you around and yet commit to safety and conservation.

  • Is it dark down there?

Yes it is!

Safety Rules for Cavern diving in the Cenotes
Basic safety rules

Some parts in the Cenotes are very dark and darkness can alter your sense of orientation, and you a feeling you could get lost easily. This is why everyone is diving with a dive light.

Your guide should be carrying all his/her full cave gear that includes a bright and long lasting primary light used for showing you around and for communication as well as 2 back up lights. And yourself should carry at least one dive light.

The waters in the Cenotes are crystal clear, and will stay that way if all divers follow the basic rules: maintain good buoyancy, swim using non silting kicking techniques and follow the guideline.

  • Will I be able to find my way?

Yes, as long as you follow the Guide Lines

Full Cave Diver course - deploy a guideline
Installing a guideline

One of the main safety rule in cavern diving in the Cenotes is referencing the guideline at all time. Your guide will explain how to identify it, how to use it and where to position yourself at all time. The same guideline will show you the way out. You should also be able to rely on your guide to follow them at all time.

We strongly recommend to dive the Cenotes. It is a unique and magical experience. Always make sure you dive well within your limits and remember the golden rule: anyone can call the dive, at any time, for any reason. So, do not hesitate to do so whenever you don’t feel comfortable.

When comes the time for you to book your dive tour to the Cenotes, remember that safety is important. Cenote diving is for advanced divers and you should be sharp on your dive skills, so don’t hesitate to refresh them by a couple ocean dives before you head for the cenotes.

Enjoy your Cenote dive 🙂

A beautiful circuit that will take you somewhere only divers can go. The maximum depth is 14m/50 feet. During the dive you will pass the halocline several time and observe beautiful speleothems while swimming around an air dome.
The blue cristaline water of Kukulkan itself is something surprising! Let the morning sun spread its rays and enjoy the show. The halocline and its blurry effect is a perfect contrast to the clear water to complete the experience. Kukulkan has also its little treasures: Aragonite cristals hidden like little gems in a jewel box .

The parc of Chikin Ha hosts 3 Cenotes, Cenotes X Tabay, Chikin Ha and Ta’ak Bil-ha. Once parked on site a walk leads us to Cenote Chikin Ha which is the beginning of two cavern lines. Both lines start in the open water and cross a wide tunnel with stunning halocline to go up the over side to Cenote Arcoiris (Rainbow).

A few minutes further south of Chikin Ha is the entrance of El Jardin del Eden (Eden’s garden). With a very large open water area this is a very popular place for different activities. Swimmers and snorkelers will love to swim around and enjoy all the colorful fish, the green algae covering the rocks gives an amazing brightness to the pond when the sun is out. The cavern permanent guideline is hidden to prevent damage from people jumping around, first part of the dive the guide will connect to the open water. Then the dives starts in a very large tunnel with dark sediment that absorbs the light. and after a few seconds you will start seeing the light from the other side of the tunnel before you reach Cenote Corral, enjoy the stunning light curtain, one of the most spectacular halocline and many fossils.

Cenote Dos Ojos –

Dos Ojos Cenotes offers among the best cavern dives in the world. Dos Ojos in spanish means “two eyes” and was named after the two cenotes right next to each other looking like two large eyes. Both cenotes are connected by a huge cavern in which you can observe some very massive columns. The cave diving exploration of the Dos Ojos system originally started there. Dos Ojos underwater cave is so amazing that it has been featured in big productions:
  • IMAX movie “Journey into Amazing Caves” in 2002
  • BBC/Discovery Channel series “Planet Earth” in 2006
  • Parts of “The Cave” movie was filmed there in 2005
Starting from Dos Ojos you will be able to do two cavern dives, both start and finish at the same place but they are completely different.  

Barbie Line

It is a circuit of 500 meters (1,600 feet) long. You will reach the second eye through the cavern and dive under ceiling along its surface, showing daylight and surface very near by. A highly decorated place with massive brownish formations that will give you the opportunity to swim between huge columns and stalactites.

Bat Cave

It feels almost like cave diving. The dive is a lot darker as it mostly goes around an air dome, the bat cave, with very little daylight penetration. This dives is also highly decorated with much thinner and more subtile and fragile speleothems.  

Cenote The Pit

Cenote The Pit - Dos Ojos
Cenote The Pit – Dos Ojos
The Pit is a stunning Cenote far into the jungle, situated upstream from Cenote Dos Ojos, and is part of the Sistema Dos Ojos, one of the biggest subterranean river system in the world. The Pit is 391 ft/119 m that makes it the deepest cenote in the State of Quintana Roo. Originnaly discovered by divers arriving from Dos Ojos Cenote, it is a fascinating place that still goes under very challenging exploration. Diving in this very unique Cenote will bring some unforgettable memories. Although at his best in summer under bright sunshine, the magic is such that you can enjoy this cavern dive all year around. Somewhere around 30m/100ft you will cross a fine hydrogen sulfate cloud. A dead trees sticking out of the cloud makes you feel like diving in a foggy dead forest.Then we slowly ascent up to the cavern ceiling whitch is highly decorated with scalatites of all sizes and shapes.You will get to see the beginning of the cave dives that leads to Dos Ojos and be able to imagine the explorators’ feelings when they first reached there…

  • Cenote Dream´s Gate

Cenote Dreams´gate
Cenote Dreams´gate

A very well deserved name for this Cenote! It is litteraly the dream cave!! Beautiful, entirely decorated with the finest speleothems, long thin columns, stalactites, stalacmites… big ones, small ones, there are everywhere! Go one way and you will be amazed! Go the other way and you will see something different. These are two amazing dives, but you have to work your way to it to really get the most of it! Dive cenotes, learn from your guide, observe, get the feeling and the level of comfort, crucial to enjoy the place.

Dreams´gate Cenote
Dreams’ gate Cenote
Cenote Dream´s gate – Upstream & Cenote Dream´s gate – Downstream

Both dives are very shallow, 20 ft (6m) and covered with very thin sediment, meaning very good buyancy skills are mandatory. We will take you there after evaluating your skills on previous dive. A loss of buoyancy is not only going to ruin the dive but is also going to cause irreversible damage.

Casa Cenote – Cenote Manati

Cenote Manati - Casa Cenote - Tank Ha Also known as Cenote Tank Ha Something different! A simple dive full of surprises. It is an open cenote surrounded by the mangrove. Casa Cenote connects one of the longest underwater Cave Systems in the world with the ocean. Located a few kilometers north of Tulum  while diving the cavern in Casa Cenote you will truly get the feeling of diving underneath the jungle. The Cenote has a shape of a horse shoe in the middle of the mangrove. The dive consists in following one side under the roots to protect from the current. Yes there can be current there! Navigate through passages and fissures in the limestone and then come back through the beautiful tunnels under the mangrove. Due to the connection with the ocean, you will dive in brackish water and will meet both fresh and saltwater fish. If you are on a lucky day, be patient and keep your eyes wide open for cormorans fishing. There is nothing like seeing a bird underwater in the middle of a mangrove. This cenote is perfect for novice divers and will give you the possibility to see more life than in the other cenotes. It also has a very nice halocline and beautiful light effects. The maximum depth is 8m/30 feet.
Temple of Doom Although its nickname – Temple of Doom – sounds threatening, it’s really just refers to the three holes in the top of the cenote that create the image of a skull.   At just over 15m/50 feet, it’s relatively shallow and the ambiance is outstanding and full of surprises.  You enter with a 3m/10 ft high giant step. You will come accross a stunning halocline with bluish salt water that highly contrasts with the slightly tannic fresh water. The shallow part is highly decorated with very interesting layers of speleothems.

Cenote Actun Ha
It is located on the Coba Road 15 minutes from the town of Tulum. The Cenote is just a few meters from the road and has extremely easy access. For that reason, taxi drivers used to wash their cars there. Carwash presents a large and shallow open water pool with two entrances (upstream and downstream) to the cave system. The Cavern general takes place in the upstream side which is way bigger and more decorated. There is no permanent Cavern Line in Carwash so your guide will install one using a primary reel. You will follow that linbe during your dive and come back the same way to recollect it.

Winter light at the entrance of the gigantesc cavern of Carwash
During the summer months, an algae blooms at the surface of the cenote. It can be a few meters thick and reduces considerably the visibility. That layer can be quite warm and it filters the sunlight but once you pass below it the water is crystal clear and feels a lot cooler. Below the algae layer the light takes a surprizing and amazing greenish colour. That you will enjoy looking at all time during your cavern dive. The dead trees fallen at the entrance create a beautiful forest that gives a great subject and composition for photographers. At the furthest point of the cavern, where the beginning of the cave is pointed out by a clear sign you will observe many brownish cave formations.. The Open water is also ofgreat interest. The basin has many water lillis as beautiful as fragile and very colourfull. You will see many turtles and don’t forget to look around for the crocodile as you come back to the open water. Carwash is also a popular training site for full cave diving training.

Cenote Angelita

Angelita in spanish means “little angel”. It is an atypical Cenote dive in the Riviera Maya and it is a once in a lifetime experience underwater. Situated 17kms south of Tulum, it is the furthest cavern dive site from Playa del Carmen.

After a 5min walk through the jungle, you reach this circular shaped Cenote that goes straight down all the way to more than 60m/200ft.

After descending the clear fresh water you will reach the mystical hydrogen sulfate layer at around 30m/90 ft.  It looks like a huge cloud surrounding an island covered with dead trunks and branches. Those of you who feel comfortable will cross the cloud. The cloud itself is like a very heavy fog with low visibility and a bit smelly. Then once you are below the cloud the visibility is perfect again but it is completely dark, giving the feeling of being in a forest at night.

After a few minutes, we go back up and start ascending in circles along the walls. There are few stalactites but the few ones are huge and are here to remind us those times when the water level was much lower. Angelita is a dive for the experienced diver because of its depth. It is also very popular for Technical Diving.
