There are nearly 7,000 Cenotes in Mexico's Yucatán Peninsula,  Here are some photos from just 8 of them (Chac-Mool, Kukulcan, Dos Ojos Barbie Line, Prima Ojo, Chikin Ha, Tajma-Ha, El Pit, and Nicte-Ha). 

To dive in the Cenotes has been on my bucket list for years and it was certainly a fantastic experience.
