Cueva Alfredo Jahn Natural Monument

Cueva Alfredo Jahn is a limestone cave system in Birongo that stretches roughly 4 kilometers through interconnected passages and chambers. The cave network features multiple entrances and contains flowing underground streams that shape its passages.

The site received official protection in 1978 when the Venezuelan government declared it a Natural Monument. This designation recognized its value as both a geological formation and a location of scientific interest.

The cave is named after Alfredo Jahn, a Venezuelan naturalist who dedicated his career to exploring and documenting the country's geological wonders. The site reflects local pride in scientific discovery and environmental exploration.

Visitors should wear sturdy shoes with good grip, bring reliable lighting, and bring waterproof gear since water seeps through the rock walls throughout the cave. Having a local guide is strongly recommended because the passage layout is complex and easy to misnavigate.

Inside the cave lies the Hall of Chaguaramo, a chamber filled with towering stalactites and stalagmites along with impressive limestone columns that look like frozen waterfalls. The temperature in this chamber stays pleasantly warm year-round, making it comfortable for exploration.
