Camuy River Cave Park showcases one of the largest cave networks in the Western Hemisphere, offering visitors stunning underground formations and a unique natural experience in Puerto Rico's karst region.
Camuy River Cave Park, officially known as Parque de las Cavernas del Río Camuy, is a remarkable protected area located in the municipalities of Camuy, Hatillo, and Lares in Puerto Rico. It is part of the extensive Camuy River Cave System, which is regarded as the third-largest underground cave network in the world and the largest in western hemisphere by length of explored cave passages. The geography of the park is defined by its dense karst limestone formations, caves, sinkholes, and subterranean rivers sculpted over thousands of years. The park’s ecosystem includes tropical forest habitats spanning limestone hills, which harbor a variety of native flora and fauna adapted to both surface and cave environments. Historically, the cave system has archaeological significance, with evidence of Taíno Indian presence and cultural importance dating back centuries. Visitors to Camuy River Cave Park can explore guided tours that navigate large cavern chambers, subterranean rivers, and massive cave openings, including the spectacular Cueva Clara (Clear Cave). Beyond cave tours, hiking trails offer scenic views of the landscape’s karst topography with features like sinkholes and natural bridges. The park also supports educational programs explaining geology, hydrology, and conservation challenges. Its appeal lies in the extraordinary underground experience fused with above-ground natural beauty and rich cultural heritage. Camuy River Cave Park stands out as a unique destination for adventure seekers, naturalists, and those interested in geological phenomena, emphasizing both exploration and preservation of fragile cave environments.
