Kukulkan (Little Brother)

Part of the Chac Mool system, with its entrance a couple of hundred feet from Chac Mool and reached via a small pond. A large cavern surrounds the cenote; sunlight from a side opening sends beams across the formations. From about 10 m divers enter the halocline, and the walls reveal fossil shells and corals from the ancient reef limestone. The narrow Little Brother entrance opens into a green-lit arch with roots and boulders.
