Cenote Maravilla is located in the Yucatan Jungle along the Rutas de Los Cenotes. It is a very large cenote, shaped like the bottom of an hourglass. Sunlight shines through the opening with instense beams of light. This cenote is popular with freedivers because of the beams of light and depth. A thick haze of hydrogen sulfide lies at the bottom glowing eerily and undulating.
