Cueva Ventana – Arecibo, Puerto Rico - Atlas Obscura

Arecibo, Puerto Rico

Cueva Ventana

This limestone cave offers an incredible view of the Río Grande de Arecibo valley.  

Perched high on a limestone cliff, Cueva Ventana gives visitors a chance to see Puerto Rico from a new angle. It’s name translates to “window cave,” for the way its mouth opens up to an impressive view of the valley below. 

Getting from the ground to the cave opening takes about an hour of hiking and climbing. Along the way, tour guides will share information about the plants and animals that make their homes in the cave, and the geology that makes up the cave’s interior.

Inside Cueva Ventana you’ll find impressive stalagmites and stalactites, reaching out of the floor and ceiling like jagged teeth in the gaping maw of the cavern. But the real highlight comes at the end of the short path through solid rock created by the cave. The passage finishes dramatically, opening into a hole in the face of the cliff that frames the lush Río Grande de Arecibo valley. The scenic vistas from this vantage point have attracted visitors for decades, providing views across the entire valley and down to the ground below.

Beyond the main attraction of Cueva Ventana, there are several other rocky chambers surrounding the area, including shorter and more challenging caves ripe for exploration and even spelunking.
