The Pit
Riviera Maya Cenotes · Mexico
The deepest known cenote in the Sistema Dos Ojos — a vertical shaft dropping past 100 m with a haunting hydrogen sulfide cloud at 30 m where freshwater meets ancient organic matter. Light shafts pierce the surface and fade into perfect black. Surreal and frequently called one of the most beautiful dives anywhere.
