Gran Cenote Tulum: Entrance Fee, Snorkeling and Diving

What Gran Cenote is

Gran Cenote has two open pools linked by tunnels under the rock, with wooden platforms and boardwalks around them. Bats roost on the cavern ceiling and small turtles swim in the clear water. The entry points along the boardwalk are shallow, so there is no jumping or diving in from the edge. The water stays at about 25°C (77°F) all year (How Is the Sargassum, October 2026). Cave divers know it as the start of Sistema Sac Actun: exploration of the system began here, about 5 km west of Tulum (Wikipedia).

Gran Cenote entrance fee and hours

No official site publishes Gran Cenote's prices, so these figures come from dated travel guides. Three of them, from January 2025 to October 2026, agree on about 500 pesos for general admission; an undated blog gives 300. Bring pesos in cash. The January 2025 report gives 8:10 a.m. opening, last entry at 4:15 p.m. and closing at 4:45 p.m.; a 2026 blog says 8 a.m. to 5 p.m. Plan on the earlier last entry. Every cenote's fee is on what a cenote costs.

• Admission, about 500 pesos — January 2025 (The Whole World Is a Playground) and October 2026 (How Is the Sargassum; Tulum Times).
• Life jacket rental, 50 pesos — January 2025 report.
• Snorkel rental, 80 pesos — January 2025 report.
• Locker, 30 pesos — January 2025 report.

Snorkelling and the turtles

Turtles are often in view, and visitors are asked to keep their distance. Snorkellers see the rock formations from near the cave openings. Before you get in you must shower, and sunscreen and mosquito repellent are not allowed before entering the water (The Whole World Is a Playground, 2025). Parking is limited and fills by mid-morning (How Is the Sargassum, 2026), and Tulum Times advises arriving at the 8 a.m. opening. For gear and clothing see what to wear to a cenote.

Diving the Gran Cenote cavern

Certified divers can go into the cavern to see the formations up close. A cavern dive stays in the naturally lit zone, where the exit can be seen; going past the daylight is cave diving, a technical discipline with guidelines, redundant lights and gas planning (Wikipedia). Beyond the open sections at Gran Cenote, scuba divers need a certified cave-diving guide (How Is the Sargassum, 2026). Our cenote diving guide covers certification levels, and cave diving in cenotes covers what full cave training involves.

Is Gran Cenote worth it?

It is one of the pricier cenotes near Tulum: 2026 reports put Cenote Calavera, on the same road, at 150 to 300 pesos. What the extra buys is clear water, turtles, the cavern between the two pools and boardwalks that make getting in easy. What it costs besides money is company, since the car park fills by mid-morning. If you would rather jump in or find quieter water, see Tulum's cenotes compared.
