You don’t have to be a seasoned spelunker to enjoy Río Camuy Cave Park, one of the largest such sites in the world. The caves, sculpted by the underground river from which it derives its name, were only discovered in 1958 and haven’t yet been fully surveyed.
The most accessible part is Cueva Clara. Descending into this subterranean chamber, pierced by shafts of sunlight, lined with luxuriant ferns and echoing with bat screeches, is an unforgettable experience.
Back on ground level you can peer into the enormous Tres Pueblos Sinkhole or set off on a walking trail to explore more of this thickly-forested area.
Río Camuy Cave Park is in northeastern Puerto Rico, near the north coast city of Arecibo. It makes a perfect day trip from San Juan, about an hour’s drive away, but do set out early as over-capacity sometimes forces the park to turn away visitors later in the day.
