The Basics

Three crater-like sinkholes and one cave are open to the public at Rio Camuy Cave, the third largest underground river cavern system in the world. These attractions are accessed via a trolley ride that whisks visitors to the cave entrance. Led by a park ranger with guided audio, the 90-minute cave tour offers insight into the geologic history and ecosystem of the area, while also stopping at a spot where you can hear the Camuy River roar past. The cave’s open ends allow in plenty of sunlight.

Rio Camuy Cave Park is easily accessible from San Juan on a day trip. Many travelers visit as part of an organized tour for the benefit of guided commentary and round-trip transportation. This trip is sometimes combined with a visit to the nearby Arecibo Observatory, where you can listen to the sounds of the universe from the world's largest radio telescope.
