Get off the beaten path on an underground adventure.

The caves of Puerto Rico offer adventurous visitors the opportunity to go hiking, spelunking, rock climbing, rappelling, or rafting in some of the Island's less-visited parts.

Wade through narrow rock openings waist-deep in an underground river with only a headlamp for illumination. Rappel through the mouth of a cavern alongside a giant waterfall. Discover indigenous hieroglyphs after a climb. Or, if you're looking for an easy hike and some stunning pictures, that's readily available, too. The caves of Puerto Rico offer diverse and unique ways to experience the Island that few tourists or even locals know about. 

Here are some of the best caves you can explore while visiting Puerto Rico:
