Stroll along one of the world’s longest underground rivers, among stalagmites, bats and more hidden treasures.
Visit Rio Camuy Cave Park to explore hundreds of limestone caves strung along one of the world’s longest underground rivers. This stunning area in central Puerto Rico has been carved out over centuries. While the indigenous people of area have long used the caves for shelter, it wasn’t until 1958 that westerners discovered the underground waterway. Exploration uncovered a network over ten miles (16 kilometers) long, featuring over 220 separate caves, and the third longest underground river in the world. You can feel the mystery and history seeped in these caverns. And watch out for the colony of bats that live in the shadows!
Rio Camuy Cave Park is one of the most popular tourist attractions in Puerto Rico. During peak periods it can be very busy so visit early in the day to avoid crowds. This will help ensure you are admitted before the park reaches its 1500 person capacity.
Start your visit watching an introductory video that provides some basic safety advice for first-time cavers, as well as an overview of the history of the park. Afterwards, hop on the scenic tram journey to the caves.
The caves themselves are wide and expansive. Make your way down the slippery path with care as you head towards Clara Cave and the Empalme Sinkhole. This enormous underground chamber is over 700 feet (213 meters) wide. Look to the ceiling to see some of bats that call this place home. In fact, these caves are inhabited by some half-million bats (13 species). But, don’t worry, they’re content with observing visitors from afar.
The Rio Camuy Cave Park is located approximately 14 miles (22 kilometers) from Arecibo in northwest Puerto Rico. It can be reached by car and there’s free parking available on site. There’s no public transportation to the park, however some charter buses do service the area. The park is closed Monday and Tuesday and there is a modest admission fee.
