2. Rio Camuy Caves
About one hour’s drive from the capital of San Juan is where the planets third largest river carves out roughly 220 caves over the course of ten miles.
You can visit with one of the many organized tour groups or find an adventure operator who will show you what spelunking was meant to be.
Geologists hypothesize that there could be as many as 800 undiscovered caves there. Run by the Parques Nacionales, the caves are located in a 300-acre park and park guides offer walking tours of the area.
This is nature at her best and most stunning. And if you’re wondering what that heat is, it’s the heat that’s given off by the hundreds of sleeping bats that nest at the top of the caves.
