Parque Nacional de las Cavernas del Río Camuy

Parque Nacional de las Cavernas del Río Camuy is located in the karst region of northern Puerto Rico, encompassing an extensive limestone cave system formed by the Camuy River carving through subterranean passages. The park features an outstanding combination of natural geological features, including massive caverns, sinkholes, and an underground river that flows through approximately 10 miles of tunnels. The ecosystem within the caves supports specialized fauna such as bats and cave-adapted invertebrates, while the aboveground forested area is home to a range of tropical species. Established in 1986 and managed by the Puerto Rico Department of Natural and Environmental Resources, this park presents visitors with opportunities for guided cave tours, hiking, wildlife observation, and educational programs detailing the region's natural and cultural history. Notable landmarks include the Cueva Clara and Cueva Juan Diego, expansive caverns renowned for their impressive formations and ease of access, as well as the Tri-Town Sinkhole (Sumidero Tres Pueblos), one of the largest natural sinkholes in the Western Hemisphere. Visitor appeal lies in the park's combination of adventure, education, and natural beauty, appealing to families, spelunkers, and nature enthusiasts alike. It serves as a critical conservation area protecting vital karst geological features and native species. The visitor experience is enhanced by well-maintained trails, safe guided tours, and informative visitor center exhibits, making it a standout destination within Puerto Rico’s protected places.
