Haiton del Guarataro

Haiton del Guarataro is a cave system in Sierra de San Luis featuring a dramatic vertical entrance shaft. The cave extends deep underground and contains underground waterways that flow through its passages.

British researchers conducted the first systematic exploration of the cave system in 1973, documenting its structure and extent. This expedition marked the beginning of scientific understanding of the underground site.

Local legends speak of supernatural entities that have captured the imagination of inhabitants for generations, shaping how people understand this place. These stories remain part of how communities relate to and discuss the cave today.

The cave is located at high altitude in mountainous terrain and requires specialized equipment and experienced guidance to explore safely. The vertical sections and deep passages demand physical preparation and proper safety gear.

An underground river flows through the cave, ranking among the largest subterranean waterways in the country. This hidden water system creates its own underground ecosystem that researchers continue to study.
