World’s longest underwater cave is found in Mexico
Measuring 215.6 miles, the cavern is full of ancient Mayan artefacts, as well as the remains of early settlers
A tunnel has been discovered beneath Mexico’s Yucatan Peninsula that scientists believe could be the largest underwater cave in the world.
The 215.6 mile-long cave is connected by two of the world’s largest flooded caverns – Sac Actun and Dos Ojos in Tulum, Quintana Roo. The cave has beaten the record of 167.9 miles, formerly held by Ox Bel Ha in the same region.

The discovery was made by the research unit Gran Acuifero Maya which has been exploring the two caverns for twenty years in an attempt to find a link.
It took 10 months of extensive exploration before the caves were found. Science Alert describes it as an “underwater wonderland” that could also “reveal “lost secrets of the ancient Maya civilisation”.
“This immense cave represents the most important submerged archaeological site in the world,” says underwater archaeologist Guillermo de Anda from Mexico's National Institute of Anthropology and History. “It has more than a hundred archaeological contexts, among which are evidence of the first settlers of America, as well as extinct fauna and, of course, the Maya culture.”

Exploration teams have found artefacts from Mayan settlers, who dominated the region at the time, including the remains of extinct plants, Mayan archaeology, ceramics, graves and even the remains of early human settlers in the region.
What also makes this finding immensely valuable, according to National Geographic, is that it supports a “great biodiversity that depends on this enormous system and represents an extensive reserve of fresh water that has given life to this region of the Yucatan Peninsula since time immemorial.”

The next phase includes an analysis of the water quality of the Sac Actun System, and a study of its biodiversity and conservation.
