The Caribbean is famous for its undersea treasures, something we’ve touched on here and here, but what’s less known is that the region is also home to some pretty amazing underground attractions. My favorite, and arguably the most impressive, is the Rio Camuy Cave Park in Puerto Rico.
Okay, really there is no argument: Rio Camuy is by far the most impressive underground attraction in the Caribbean. After all, there are only two other cave systems on the entire planet that approach the Rio Camuy Caves in size, and neither of them can boast a tropical underground river.
Located near the town of Arecibo on Puerto Rico’s north coast, the Rio Camuy Caves are part of an immense network of natural limestone caves and underground waterways carved out by the Camuy River, the third-largest underground river in the world. More than 10 miles of caverns, 220 caves and 17 entrances to the cave system have been mapped in the 52 years since the caves were officially “discovered,” though this is only a fraction of the entire system.
