Las Bocas Canyon (Spanish: Cañón Las Bocas) is a steep gorge carved by the Frío River, located on the town boundary between the municipalities of Barranquitas and Comerío in the central region of the main island of Puerto Rico. Situated between the eponymous main subrange of Cordillera Central and the Sierra de Cayey subrange, it is notable for its untouched forests and the large population of kapok (Ceiba pentandra).[1][2] Las Bocas, along with San Cristóbal Canyon, its larger neighbor to its immediate south, form part of the La Plata River basin.[3]
