Cueva de Villa Luz

Cueva de Villa Luz is a limestone cave system near Tapijulapa featuring natural skylights and underground springs that release hydrogen sulfide gas throughout its passages. The network extends over two kilometers and is made accessible to visitors through wooden walkways.

The cave was first systematically explored in the 1960s and later underwent extensive scientific investigation. This research revealed its distinctive geological features and complex biological ecosystems.

The Zoque people traditionally perform the Ceremonia de la Pesca at the end of the dry season to request permission for fishing inside the cave.

Visitors should come prepared for challenging conditions due to hydrogen sulfide gas present in the cave. The site provides safety equipment and marked routes help with navigation through the explorable sections.

The cave contains living stalactites formed by bacteria that produce sulfuric acid with pH levels near zero. These extremophile organisms continually grow and create one of Earth's most acidic environments.
