Cenote Dos Ojos: Mexico

11 of 12

An ethereal turquoise world greets divers as they float past underwater stalactites and stalagmites illuminated by dramatic shafts of sunlight. Part of the third-largest underwater cave system in the world, the Dos Ojos or “Two Eyes” cenote is two sinkhole entrances to crystal-clear, freshwater-filled caverns in the Yucatán, where cracks in the limestone landscape created a network of caves and sinkholes.

Why It’s Cool: Both “Ojos” are well suited to snorkelers. If you have an open-water certificate, you can dive with a guide from Dos Ojos Scuba Shop (groups of four maximum).
