Camuy River Cave National Park


The Camuy River Cave Park has a fascinating history that dates back thousands of years. The caves are part of an extensive network of natural caverns stretching over 15 kilometers of limestone and underground rivers, carved by the Camuy River, one of the world’s largest underground rivers. It was discovered in 1958 and subsequently documented in 1973 in a book written by Russell and Jeanne Gurnee, titled "El Río Camuy" (The Camuy River).

Established in the year 1987 with the Spanish name "Parque Nacional de las Cavernas del Río Camuy", this park houses over 220 caves, with 17 main entrances providing access to this impressive underground system. The mentioned book details the natural wonders found within these caves, which have since been subjects of study and admiration.
