Cueva de Villa Luz
Cueva de Villa Luz (Cave of the Lighted House, also known as Cueva del Azufre and Cueva de las Sardinas) is a cave near Tapijulapa in the southern Mexican state of Tabasco. The springs within the cave are rich in hydrogen sulfide, a gas that is a potent respiratory toxicant and smells like rotten eggs. Within the water, sulfide is oxidized to colloidal sulfur, which gives the water a milky appearance, and sulfuric acid. The cave essentially is a maze about two kilometers in length and primarily etched out of limestone by the sulfuric acid in the water. Hydrogen sulfide is also used by chemoautotrophic bacteria, which form the base of the food web.
The cave is a popular tourist destination and visited by many, partly because it is easily accessible. It has been featured on the BBC's series Planet Earth, and Wonders of the Solar System.
