Sistema Dos Ojos, Cave system in Quintana Roo, Mexico.
Sistema Dos Ojos is an underground cave system in Quintana Roo, Mexico, that stretches for 82 kilometers and has 28 cenotes as natural openings along the coast of the Yucatan Peninsula. The passages run through limestone formations with clear water that reveals stalactites, stalagmites, and partly submerged chambers.
Divers began exploring the caves in 1987 and discovered new connections to neighboring systems over the following decades. In January 2018, a direct link with Sistema Sac Actun was confirmed, greatly expanding the entire network.
The name means "two eyes" and refers to two nearby cenotes that once served as entryways to the site. The underwater formations show traces of ancient burials and offerings that visitors can observe during guided dives.
Dives take place in small groups with no more than four participants per guide, and water temperature stays at 25 degrees Celsius (77 degrees Fahrenheit) throughout the year. Visitors should have experience in cavern diving or at least in confined-space diving, as some sections are narrow and dark.
In November 2010, freediver Carlos Coste set a record here by swimming 150 meters (492 feet) on a single breath. The cave also served as a filming location for underwater footage in several documentaries about prehistoric skeletons found in its depths.
