Cenotes Zapote EcoPark

Cenotes Zapote EcoPark sits on the Ruta de los Cenotes, the jungle road that runs inland from Puerto Morelos, and it is best known for a cenote that contains the dramatic underwater formations nicknamed Hell's Bells. Cave divers with specialist training reach those formations, but the park offers much more for the rest of us: open and semi-open cenotes for swimming and snorkeling, shaded platforms, trails through tropical forest and a relaxed atmosphere that is a welcome change from the beach. Admission covers a day in the park, and you can combine it with the activities available on site, which may include rope swings, zip lines and guided tours. It is a good choice for families, groups and anyone who wants to see a classic Yucatan cenote without a long drive.

Cenotes are natural sinkholes formed when limestone collapses and exposes the groundwater beneath. The water is cool, clear and refreshing, and a swim in one is one of the signature experiences of the peninsula. At Zapote the cenotes differ in character, from sunlit pools ringed with vegetation to deeper, darker basins with sheer walls.

Water quality is protected, so you will usually be asked to shower before entering and to use biodegradable sunscreen or none at all. Life jackets are available for those who want them, and snorkel gear can be rented, which lets you see the clear water, fish and rock formations.

Allow time for the surroundings. The park's trails pass through forest where birds, butterflies and the occasional iguana appear, and the shade makes the walk pleasant even in the heat. Some visitors come mainly for the swimming, others for photographs of the cenote's blue light, and others for the thrill of a rope swing or platform jump.

Diving in the deepest cenote is restricted to certified cave divers with a guide, so do not expect to see the bells without training. Check what is included in your admission, what activities carry an extra charge, and what the policies are on children, since depth and age limits apply.

Getting here is straightforward by car or tour from Cancun and Puerto Morelos, and the park fits well into a day that also includes the Puerto Morelos reef or the town's beachside restaurants. A cenote visit is cooler and quieter in the morning, before tour groups arrive, and reliably more photogenic when the sun is high enough to pierce the opening.

Bring a swimsuit, a towel, water-friendly shoes, cash for rentals and food, and an insect repellent that does not wash off into the pool. If you want to explore more cenotes in the region, compare the ATV and cenote adventure and the Puerto Morelos tours, which combine jungle driving with a swim. For a calm, natural half-day, the park is a dependable choice.
