Río Secreto Underground River

Descend into the earth and discover a hidden underground world that was only opened to the public in 2007. Río Secreto is a stunning semi-flooded cave system with dramatic stalactites, stalagmites, and crystal-clear waters that create mirror-like reflections.

This is not your typical tourist attraction – it's a genuine expedition into nature. You'll wade, swim, and walk through 600 meters of caverns, guided by experts who share the geological and spiritual significance of this sacred Mayan site.

The experience is deeply immersive. At one point, your guide will ask everyone to turn off their headlamps. In complete darkness and silence, you'll truly appreciate the power of this ancient underground realm.
