Be ready to be wowed as soon as you enter this wondrous natural attraction, tucked into the karst region of the north coast. Rio Camuy Cave formally named Parque Las Cavernas del Rio Camuy, designated the First Natural Delight of Puerto is “one of the world’s largest cave networks”. This is an excellent day trip just about a 1 hour and a 20-minute drive from San Juan, Puerto Rico. If you don’t want to drive yourself, you can conveniently book with a cavern tour guide who provides transportation from San Juan.
Rio Camuy This cave is the third largest underground cave system in the world, Rio Camuy runs through it. The main part of the cavern is massive, with a ceiling over 10 stories high. Photos can’t capture the beauty of this world-class wonder, Camuy River Cave Park is among the top ten attractions you can’t miss in Puerto Rico. Parques Nacionales (Puerto Rico National Parks) manages this 300-acre park, offering walking tours in both English & Spanish, through this enormous cave. This day will be part of one of the best day trips you can enjoy during your vacation in Puerto Rico, see our Best Things to Do in the North Region guide to see the suggested itinerary.
The Rio Camuy Cavern Tour
You will be given a set of headphones, available in Spanish and English.
Your tour begins with a fun trolley ride down the steep rolling mountainside that children will love. The adventure begins as the trolley zig-zags down the mountainside, deep down to the cave entrance where the amazement of the cavern awaits. You’ll wish the ride took longer…the temperature gets cooler as you drop down into the nest of the mountain covered with lush greens that glisten to the rays of the sun.
There are a few steps before heading through the tunnel that leads to the entrance of the cavern. The rest of the way you’ll be walking on concrete walkways with side rails. Please read the suggestions below for tips on recommended attire and care when touring the cavern.
You’ll enter through Cueva Clara, you’ll walk through diverse tunnels, some reach as high as 170 feet and span as wide as 200 feet. Depending on the time of day, heavenly sun rays come through the window pictured below. As you go deeper into the cavern you’ll be wowed by the size and magnitude of this place. Again, photos can’t really capture the splendor of the cavern, you have to be here to experience it.
Natural works of art such as spectacular stalagmites and stalactites were carved and formed by waters of the Camuy River, which is estimated to be approximately 45 million years old.
At one of the highest points of the cavern, you’ll see the largest stalagmite in Puerto Rico, an impressive sight.
As you walk, you’ll see nature at work, water streaming down the walls, forming more spectacular structures right before your eyes. During your exploration, you’ll feel the heat of hundreds of sleeping bats and hear the sounds of Camuy River running underneath.
One of the best parts of the tour is Sumidero de Empalme (Empalme Sinkhole), a breathtaking magical spot where the sun rays shine through the sinkhole entrance 450 feet above.
This sinkhole feels more like an enchanted room.
Wellsprings gently flow down the walls to create a mesmerizing melody, you can’t help but think that perhaps this is the source of the fountain of youth Ponce de Leon so desperately sought.
The rays of sunshine radiating through the opening above make the waterfalls sparkle, the foliage glisten and the trees are perfectly lit by the true master landscape architect. There’s so much beauty to take in at the Empalme Sinkhole.
Your tour guide will take you through the last part of the tour, a party for your senses if you’re into caves. You’ll be able to observe more stalagmites and stalactites and hear some cool sounds. You’ll walk through a tunnel and then over a concrete walkway suspended over the underground river, where the sounds of the water and bats seem to be right out of a Batman movie scene. As a matter of fact, the sounds of bats used in a Batman movie were recorded at the Camuy Cave.
Visiting InformationCamuy River
The tour guides will tell you that in this area you should not hold on to the handrails because of all the bat soil on the rails, management does clean them but there are just too many bats to keep them perfectly clean. If you have children please hold their hand to keep them from touching the rails. If you have a physical challenge that requires you to hold the handrails at all times, please be sure to bring thick disposable gloves with you, you can easily find these at a pharmacy, there are many on all major roads in Puerto Rico.
