For many years, members of the Mexico Cave Exploration Project have been exploring, documenting, and mapping more than 250 km/155 mi of the Ox Bel Ha cave system, making it one of the longest underwater caves in the world.

In 2016, a small team went back after many years to a historic section of Ox Bel Ha, in a remote location hidden far away in the Yucatan jungle, to continue where exploration stopped more than a decade ago.
