Cenotes (Yucatán)
Cenotes (Yucatán)
Last updated:
Rain that fell centuries ago, waiting in the dark for a light to pass.
The Yucatán Peninsula's limestone shelf is riddled with sinkholes — cenotes — that open onto some of the longest known underwater cave systems on Earth. Most recreational diving stays in the cavern zone, in daylight sight of an exit, over water so filtered it can feel like diving in air.
Conditions
- Season
- Diveable year-round
- Temperature
- A constant 24–25 °C
- Visibility
- Often 30 m or more where undisturbed
- Entry
- Steps, ladders or platforms into still, often very still, water
What this water asks
A guide and cavern or cave training for anything beyond the daylight zone, a slow fin technique that never stirs the silt, and calm attention through the halocline's blur.
The Blue Heart
Mayan cichlid (Mayaheros urophthalmus)
A hardy, patterned freshwater fish common in the sunlit cenote pools, often the only motion in water so clear it can look motionless.
Best dive areas in the cenotes
All recreational cenote diving is cavern diving: natural light in sight and a specialised guide. Cave diving requires separate training.
Dos Ojos
approx. 5–10 m · Open Water
Two cenotes joined by a wide cavern with stalactites and light beams.
El Pit
up to approx. 30 m recreational · Advanced
Vertical shaft, a halocline around 12 m and a hydrogen-sulfide cloud deeper down.
Angelita
up to approx. 30 m · Advanced
The underwater 'river': a sulfide cloud with branches emerging around 30 m.
Chac Mool
up to approx. 12 m · Open Water
Halocline, formations and an air chamber with roots.
Car Wash (Aktun Ha)
up to approx. 15 m · Open Water
Open cenote with algae, turtles and lilies; in summer the green water catches the light.
Dreamgate
up to approx. 8 m · Open Water, with a cavern guide and excellent buoyancy
Narrow passages through pristine formations; demands impeccable buoyancy and trim.
Depths are approximate: always confirm them at the local briefing.
When to go and what to expect
The water is constant through the year. What changes is the light, the rain and the crowds at the entrances.
| Period | Water | Visibility | What to expect |
|---|---|---|---|
| Nov–Apr (dry) | 24–25 °C | 30 m or more | Less rain, crisp light beams |
| May–Jun | 24–25 °C | 30 m or more | Strongest overhead light in the shafts |
| Jul–Oct (wet) | 24–25 °C | 30 m or more | Hurricane season: access may close |
Getting there and where to dive from
Cancún and Tulum airports. From Cancún, Playa del Carmen is about 1 h and Tulum about 2 h by road.
Dive bases: Tulum, Playa del Carmen and Puerto Aventuras. Centers drive divers to each cenote.
- Indicative price
- Two guided cenote dives: around USD 140–200 (indicative), depending on the cenote.
- Fees and permits
- Each cenote charges a per-diver entry, run by communities or landowners; sometimes it is included in the price.
- Certification
- Open Water for most guided caverns; El Pit and Angelita require an advanced level. Cave diving requires a cave certification.
A presence dive in the cenotes
A four-phase plan for Dos Ojos, inside your agency standards and dive plan.
Before
On the wooden platform, we listen to the cavern briefing and watch the still water for one minute. We agree on our light signals.
Below
When stable and conditions allow, notice the marine life without touching or pursuing it. Breathe naturally and continuously as trained. Keep your buddy, gas, depth and route in view; leave the observation whenever the dive needs your attention.
Between
At the surface, under the jungle, we share what most surprised us about the silence.
Beyond
At home, we turn off one light a day and listen to the dark for a moment.
The breathing in this plan is practised in Breathwork for divers. New to this? Read what Mindful Diving™ is.
Frequently asked questions
Can I dive cenotes with Open Water?
Yes, in most caverns with a certified cave guide and good buoyancy. Never beyond the daylight zone without cave training.
What is the difference between cavern and cave?
In a cavern you always see the exit light and stay within distance and depth limits. A cave goes beyond that and requires specific training and equipment.
Which is the best cenote to dive?
Dos Ojos is the ideal first dive; El Pit and Angelita are spectacular for advanced divers.
Is it cold in the cenotes?
The water stays at 24–25 °C. A 5 mm suit usually suffices for two dives.

Safety first
On scuba, breathe naturally and continuously as trained; never hold, skip or deliberately restrict your breathing. Keep attention on your buddy, buoyancy, gas and surroundings. Leave optional exercises out of descents, ascents and any demanding task.
