The caves of Puerto Rico offer adventurous visitors the opportunity to go hiking, spelunking, rock climbing, rappelling, or rafting in some of the less visited parts of the island.
One of Puerto Rico's most famous natural attractions is Cueva Ventana (Window Cave). Learn about the history of the island's indigenous people and be rewarded for the 45-minute hike to this elevated cave's iconic window-like opening with spectacular views of the Rio Grande de Arecibo valley.
Located on the roaring Atlantic coast is Cueva del Indio (Indian Cave), named after the indigenous hieroglyphs found carved into the rocks. This historical ceremonial park has more than 200 petroglyphs, three ceremonial plazas, hiking trails and camping areas. Admire dramatic views of crashing waves, impressive cliffs, and a natural bridge formed from rocks.
The Parque Nacional de las Cavernas del Rio Camuy (Camuy River Cave Park) is an extensive cave system located in northwestern Puerto Rico. The caverns are part of a large network of natural limestone caves and underground waterways carved out by the third largest underground river in the world, the Rio Camuy. Over 10 miles of caverns, 220 caves and 17 entrances to the Camuy cave system have been mapped to date. As of January 2019, the park is still closed due to Hurricane Maria recovery.
