Imagine being in a place with complete darkness, where your eyes will never adjust and the only light that exists is that of your flashlight. A place where silence is such that if you stand still for a moment the only sounds you will hear are your breathing and the drops of water that fall sporadically from the stalactites.

Secret River (or Pool Tunich in Maya) is a set of galleries and underground rivers formed from rock erosion. The grotto fabric is the longest of its kind (not flooded) in the entire Yucatan Peninsula.

Among the cenotes that can be found in Yucatan, Río Secreto stands out and is called "Crystal Museum", since it has no true relationship with the other underground caves that can be visited in the state, being this rich in natural crystal formations and discovered less than 10 years ago.

Definitely an underground natural paradise near Tulum!
