The best cenotes for diving in the Riviera Maya, one by one

How to choose a cenote and get it right

There are over six thousand catalogued cenotes on the peninsula and around twenty that are dived regularly. They are not interchangeable: depth changes, what you see changes, and the level required changes.

Three questions settle it:

What certification do you hold? Open Water rules out El Pit and Angelita, which go past 18 metres. Advanced opens everything.

What do you want to see? Light beams, halocline and the deep cloud are three different spectacles, and they do not coincide in the same cenote.

How many people can you tolerate? Dos Ojos is the most beautiful and the busiest. Siete Bocas is nearly as good and usually empty.

Below, cenote by cenote, with what you actually need to know before booking.

Casa Cenote: the easiest, and the best place to start

Depth: 3–8 m · Level: any, including uncertified · Visibility: 15–25 m

It is not a cavern but an open channel through mangroves that connects to the sea a few hundred metres away. That makes it unlike everything else here: sky overhead the whole time, plenty of light, and a sharply defined halocline at barely four or five metres.

It is the only place we run the cenote Discover Scuba Diving, because there is no ceiling and the depth is minimal. It is also the best first cenote if you hold Open Water but have not dived in a while: you get used to the weighting and the halocline without the psychological weight of a ceiling.

You see mangrove fish, freshwater turtles and, with luck, «Panchito» — a small crocodile that lives in the area and that the guides know well. He is harmless if left alone, and no trip goes near him deliberately.

Dos Ojos: the light beams from the photographs

Depth: 8–12 m · Level: Open Water · Visibility: 40 m+

The most famous cenote on the Riviera Maya and, by a distance, the one that produces the photographs everyone has seen. Two openings connected by a cavern system — hence the name, «two eyes».

There are two lines. The Barbie line is the classic: shallow, heavily decorated with stalactites and stalagmites, light beams crossing the chamber. The Bat line leads to an air chamber with bats in the dome — darker, and more striking.

The price of fame is people. Between 11:00 and 13:00 several groups may be in the water at once. It is still worth it, but consider going first thing if you prefer quiet, accepting that the beams will be less vertical.

Chac Mool: textbook halocline without going deep

Depth: 12–15 m · Level: Open Water · Visibility: 30–40 m

If you can only do one cenote and you want to understand what a halocline is, this is the one we recommend. The boundary between fresh and salt water is strongly defined and you cross it several times in a single dive, so there is time to take the sensation in.

It also has the Hall of Light: a large chamber with an overhead opening that admits one clean beam which, at midday, reaches the floor. It is one of the few places where the photograph works even without specialist gear.

The entry is comfortable, with a platform — welcome when the kit is heavy.

El Pit: the deepest, and the cloud

Depth: 30–40 m · Level: Advanced Open Water · Visibility: 40 m+

The deepest cenote in the Dos Ojos system and one of the most striking dives in Mexico. The entrance is a circular shaft; from the bottom you look up and the disc of light is small and very far away.

Below about 28 metres the hydrogen sulphide layer appears, a dense haze that looks like smoke. You pass through it, and underneath the water is clear again over a floor scattered with ancient timber.

Advanced Open Water is required without exception, and you want your consumption under control: at 35 metres air goes quickly, and this is not a dive to arrive at marginal.

Angelita: the tree inside the cloud

Depth: 30–40 m · Level: Advanced Open Water · Visibility: 30 m+

Angelita is an isolated cenote in the middle of the jungle, unconnected to other systems. A cylindrical shaft with vertical walls, and at its centre, around thirty metres down, a dead tree emerging from the hydrogen sulphide layer.

The image is hard to describe: the tree appears to stand on an island floating above cloud. It is one of the most photographed dives in Mexico and also one of the most austere — no stalactites, no decoration, just the shaft, the cloud and the tree.

It lies further south, near Tulum, so the day is longer. It is usually paired with El Pit for a day of two deep dives.

Dreamgate: the most fragile decoration of them all

Depth: 6–10 m · Level: Open Water with solid buoyancy · Visibility: 30 m+

Dreamgate is the most heavily decorated cenote in the area: the density of stalactites and stalagmites is such that in places you thread between them with millimetric care. Many are as thin as drinking straws and thousands of years old.

That is exactly why it demands the most buoyancy control. It is neither deep nor technical, but a diver dragging the bottom here does irreversible damage. With fewer than twenty dives, save it for the second trip.

Siete Bocas and Cenote Búho: the ones nobody asks for

Depth: 8–14 m · Level: Open Water · Visibility: 30–40 m

Siete Bocas sits near Puerto Morelos and takes its name from its several roof openings. You move from chamber to chamber and a different beam of light enters each one. It has almost everything Dos Ojos has, with a fraction of the crowd.

Cenote Búho — also referred to as Cenote Tajma Ha in some of the literature — is another lightly visited system, with heavily decorated sections and a clear halocline. It tends to come up from divers who already know the area and want something different.

Both are the right answer if you are here in high season, if you have already dived Dos Ojos, or if you would simply rather have a cenote to your own group.
