Cenote Aktun Ha

Cenote Aktun Ha lies about eight kilometers from Tulum on Mexico's Yucatan Peninsula, a karst sinkhole more than fifty meters wide formed by the collapse of limestone into an underlying flooded cave system, with an average depth of about three meters opening into cavern passages reaching down to roughly eighteen meters. Its Mayan name means Water Cave, but it is far better known by its nickname, Carwash, earned because taxi drivers once washed their vehicles beside it along the Tulum-Coba highway. Its open pond-like surface leads into cave passages lined with stalactites and other speleothems, and its water occasionally carries a greenish tint from seasonal algae growth. This entity documents Cenote Aktun Ha specifically as a geological formation, a karst sinkhole near Tulum nicknamed Carwash and known for its stalactite-lined cave passages.
