Cavernas de Venado

General Information About Cavernas de Venado

The Venado Caves Tour is one of Costa Rica’s most authentic underground adventures, offering a unique combination of geology, exploration, and soft adventure. Located near the Arenal region, this limestone cave system was formed millions of years ago by tectonic activity and an underground river, creating an impressive network of chambers, tunnels, and natural formations.

Guided by experienced local guides, visitors enter a fascinating subterranean world where nature tells its story through rock, water, and time. This is not a conventional walking tour — it is a true spelunking experience, ideal for travelers looking for something different and memorable.
