These are the entrances to the Dos Ojos Cenote. Dos Ojos means "two eyes" as from an aerial view the cenote entrances represent a pair of eyes. These entrances are used by snorkelers and scuba divers to explore the underground caves. I snorkeled here twice, absolutely amazing; the water is rainwater filtered through limestone, it is the clearest/purest water I've ever seen. The Bat Cave was home to a dozen vampire bats -- you can't see them in the pano, but trust me, they're there!
