Guajataca Forest Reserve

Guajataca Forest Reserve, located in the municipalities of Isabela, Quebradillas, and San Sebastián in northwest Puerto Rico, covers rugged karst limestone hills and valleys at elevations ranging from about 300 to 2,600 feet. Established in 1943, the reserve protects a subtropical moist forest ecosystem characterized by diverse plant species, including native hardwoods, palm groves, and ferns. It is one of the few areas in Puerto Rico sustaining native wildlife such as the Puerto Rican emerald hummingbird, the Puerto Rican woodpecker, and the endangered Puerto Rican boa. Guajataca's topography reveals caves and sinkholes typical of karst landscapes, adding geological interest. The reserve features a network of trails of varying lengths and difficulty that offer hiking and mountain biking. Notable sites include the panoramic lookout points offering expansive views of the Río Guajataca valley and adjacent coastline. Though remote, the area draws local visitors interested in nature walks, birding, and picnicking. The forest reserve's cooler, moist microclimate contrasted with coastal regions makes it a refreshing natural refuge. Management focuses on conservation, environmental education, and promoting sustainable outdoor recreation. Limited visitor infrastructure maintains the forest's wild character. Guajataca is a unique destination that showcases Puerto Rico’s natural heritage amid limestone hills and rich biodiversity.
