Cenote Carwash is a relaxed open-air cenote north of Tulum, known for a lagoon-like surface area, lily pads, and an easy cavern that opens into bright light on the way back out. It suits divers who want a calmer cenote profile with clear water, broad space, and a mix of fish, turtles, and an occasional small crocodile. The draw is the contrast between the open garden and the darker cavern rather than a deep or technical descent.
