More ways to explore the area's outdoor wonders
You stand at the limestone rim, warm air washing over you, and a bowl of glassy water drops away into shadow—the cenote dares you to breathe slowly and look down. In Tulum, these sinkholes are blue-green windows into an underground river system. Light shafts pick out rock formations; the water is clear enough to read the contours of stalactites and the slow drift of freshwater fish.

Use reef-safe sunscreen

Practice equalization
Swim with your jaw and ears warmed up—frequent equalization prevents discomfort during descent in confined cavern sections.

Morning slots offer the best light and visibility and avoid the busiest times when multiple groups share the cenote.
Listen to your instructor
Follow the guide’s buoyancy and finning instructions to avoid stirring sediment and to stay safe in low-overhead areas.
Reef-safe sunscreen
Protects the water’s ecosystem and is usually required by park operators.
Swimsuit

Quick-dry towel
For comfort after the dive and during transit back to the meeting point.
Water shoes or sandals
Useful for walking over limestone edges and uneven entry zones.
