Tour Rio Camuy Caves, one of the world’s most massive cave systems, and see cathedral-like caverns and a mysterious river that flows for miles underground.
What to Expect
This tour takes you from San Juan to north-western Puerto Rico and the third-largest underground river cavern system in the world.
Visit the Rio Camuy Cave Park, where you’ll enjoy a guided tour of this marvel of nature. In the park, 3 crater-like sinkholes and 1 cave are open to the public.
You’ll encounter sinkholes and cathedral-like caverns, eons-old stalactites and stalagmites, and a mysterious underground river. Few cave systems in the world are as massive or dramatic as the Rio Camuy Cave Park, and no other has a thundering tropical river traversing countless miles of underground channels.
Rio Camuy Caves with Arecibo Observatory Full-Day Tour
After exploring the cave system, your tour continues to the Arecibo Observatory. Nestled in the mountains of northern Puerto Rico, the observatory is home to the world's largest radar/radio telescope.
Scientists from around the world make use of the giant 1,000 foot-diameter dish to listen to the universe. You’ll have views of the huge telescope from an observation platform, where its austere metallic symmetry shimmers in dramatic contrast to the dense, green, tropical landscape.
