Exploring Caves in Puerto Rico

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. Visiting the caves of Puerto Rico offers diverse and unique ways of experiencing the Island, which not many tourists or even locals know about. 

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

It's a stunning reveal at the opening of Cueva Ventana in Arecibo.

Cueva Ventana


One of the most recognizable caves in Puerto Rico isn't underground but instead looks out over the Río Grande de Arecibo valley, creating a window-like opening on the sheer rock face of a mountain. This unique framing of the valley, river, and town below earned the cave its name, Cueva Ventana (Window Cave). Both locals and visitors eagerly snap photos of the Instagram-worthy view from the cave's opening.

Aventura Cueva Ventana is an ecotourism company that offers guided hikes of the cave, with a special rate for Puerto Rico residents.

Located inside the Guajataca State Forest in the northwestern town of Isabela, Cueva del Viento (Wind Cavern) is easily accessible via trails originating at the parking area and ranger station at KM 9 on Route 446. Once you reach the cave entrance, steps lead down, but inside there is no illumination or guardrails, so bring sturdy footwear and flashlights if you want to explore the cave. The cave is made of limestone, with beautiful stalactite and stalagmite formations. Be warned the cave is also home to many, many bats.

Cueva del Indio


Right on the roaring Atlantic coast is Cueva del Indio, or Indian Cave, named after the indigenous hieroglyphs found carved into the rocks. The entrance fee is $5 and will give you access to impressive cliffs, views of crashing waves, and a natural bridge formed from rocks. Before Hurricane María, there was a ladder leading down to the cave, which is now gone. 

Experienced climbers can still make the descent down to the cave where there are rock carvings made by the Taínos, the tribe that lived on the Island before Columbus and the Spaniards arrived.
