A legend has it that taxi drivers used to wash their cabs here and to this day Aktun-Ha is still referred to as Car Wash, despite the story being somewhat embellished. It's still a good swimming spot and several dive shops teach cave and cavern diving classes here. It's 7.5km west of Tulum heading toward Cobá.

The cenote is part of a cool cave series with names like the Chamber of Horrors, Chamber of the Ancients and Room of Tears, to name a few.
