Dos Ojos

Dos Ojos (from Spanish meaning "Two Eyes"; officially Sistema Dos Ojos) is a flooded cave system located north of Tulum, on the Caribbean coast of the Yucatán Peninsula, in the state of Quintana Roo, Mexico. The exploration of Dos Ojos began in 1987 and still continues. The surveyed extent of the cave system is 82.0 kilometers / 51.0 miles and there are 28 known sinkhole entrances, which are locally called cenotes. Dos Ojos lies broadly parallel to and north of the Sac Actun cave system. Dos Ojos has remained in the top ten, if not the top three longest underwater cave systems in the world since its discovery in the late 1980s.
