🏞️ San Cristóbal Canyon

San Cristóbal Canyon is a canyon carved by the Usabón River, located on the town boundary between the municipalities of Barranquitas and Aibonito in the central region of the main island of Puerto Rico. Situated between the mountain subranges of Cordillera Central and Sierra de Cayey, San Cristóbal measures 9 kilometers in length and reaches up to 750 feet in depth, making it the deepest land canyon in Puerto Rico and the West Indies in the Caribbean. Home to some of the tallest waterfalls and hundreds of species of flora and fauna in the island, the canyon is government-protected as a natural area since 1978, which came after the site was used as a land fill from 1954 to 1974. San Cristóbal and its northerly neighbor of Las Bocas Canyon are part of a larger canyon system belonging to the La Plata River basin in the central mountainous region of Puerto Rico.
