Mountain Pine RidgeThis is located on the west side of the Maya mountains, with 1600 foot waterfalls, deep-winding rivers, and awesome caves. The 300 square mile forest reserve majestically spouts a fantastic scenery. The Rio On Pools are only one of the great attractions at Mountain Pine Ridge. Water cascades down a gorge from the Rio On Pools in the Mountain Pine Ridge area near Rio Frio Cave. Hang out in the cool pools or get a natural massage by sitting under one of the waterfalls.
