Mexico has more than 6,000 cenotes — natural freshwater sinkholes carved into the Yucatán's limestone bedrock. They were sacred to the ancient Maya and remain the region's defining attraction for travelers in 2026. This guide covers the three types, the best cenotes to visit, current entry fees, what to pack, and the safety rules every traveler should follow.

What Is a Cenote?
A cenote (seh-NO-tay) is a natural pit or sinkhole formed when the limestone shelf above an underground river collapses, exposing the freshwater below. The Yucatán Peninsula has no surface rivers — every drop of fresh water sits in this hidden underground network, the longest cave system on Earth. The Maya considered cenotes portals to the underworld (Xibalba) and used them for both drinking water and ritual offerings.
The Chicxulub asteroid impact 66 million years ago shattered the limestone here, accelerating the karst process that eventually created the cenote ring you see on satellite maps today.
Types of Cenotes
Cenotes are usually grouped by age and how much of the original cave roof remains. Older cenotes are wide open; younger ones are still mostly underground.
| Type | What It Looks Like | Example |
|---|
| Open | Full sun, exposed pool, often surrounded by jungle. | Cenote Azul, Cenote Zaci |
| Semi-open | Partial cave roof with skylights and hanging vines. | Ik Kil, Gran Cenote |
| Closed (cave) | Mostly underground, accessed by stairs into a cavern. | Suytun, Dos Ojos, Choo-Ha |
| Ancient | Collapsed and weathered into wide jungle pools. | Cenote X'Canché, Yokdzonot |
The Best Cenotes to Visit
Gran Cenote (Tulum)
The most photogenic semi-open cenote in the Riviera Maya. Crystal-clear water, two connected caverns, stalactites, turtles and small fish you can snorkel with. Entry $25, open 8am–5pm. Arrive at 8am to have it nearly to yourself.
Dos Ojos (Tulum)
Two connected cave cenotes — "Two Eyes" — famous for cavern diving and the IMAX-quality light beams. $25 entry includes both eyes; snorkel rental $5; guided cavern dives $90–$130.
Suytun (Valladolid)
The Instagram-famous cenote with the round stone platform and vertical light beam. Beam appears November–February, 11:30am–12:30pm. Entry $10. Crowded — go at opening.
Ik Kil (near Chichen Itza)
A massive open-roofed cenote with hanging vines, a 3-meter jump platform, and easy stairs. Entry $12. Pair it with Chichen Itza in the morning, swim here at lunch.
Cenote Azul (Bacalar / Riviera Maya)
The Riviera Maya version is a free open cenote off Highway 307 just south of Playa del Carmen — entry $5. Bacalar's Cenote Azul is a 90-meter-deep open lagoon-cenote, $5 entry, with floating docks and palapas.
Entry Fees & Hours (2026)
- Gran Cenote: $25 — open 8am–5pm.
- Dos Ojos: $25 — open 8am–5pm.
- Ik Kil: $12 — open 9am–5pm.
- Suytun: $10 — open 9am–5pm.
- Cenote Zaci (Valladolid downtown): $5 — open 8am–6pm.
- Cenote X'Canché (Ek Balam): $7 — open 8am–4:30pm.
- Yokdzonot (community-run): $5 — open 9am–5pm.
Most cenotes are cash-only in Mexican pesos. Bring small bills — change is limited at remote cenotes.
What to Bring
- Reef-safe biodegradable sunscreen (or skip sunscreen entirely — many cenotes prohibit it).
- Quick-dry towel and a dry bag for valuables.
- Water shoes — limestone steps can be sharp and slippery.
- Snorkel and mask (rentals are $3–$5 but quality varies).
- GoPro or waterproof phone case for underwater shots.
- Cash in pesos for entry fees, parking, and rentals.
- Rashguard if you chill easily — water sits at 75–78°F year-round.
Safety & Etiquette
Cave diving has killed certified open-water divers who entered without cavern training. Only dive cenotes with a TDI/PADI cavern or full cave certification, or take a guided cavern tour with a licensed operator.
- Shower before entering — sunscreen and bug spray kill cenote ecosystems.
- Wear the life vest if one is offered, especially in cave cenotes.
- Don't touch stalactites — skin oil stops their growth permanently.
- No glass containers, no food in the water.
- Tip the local kids who guard your shoes ($1–$2).
- Watch the weather — flash floods can affect open cenotes after heavy rain.
