Caño Tiburones Nature Reserve is Puerto Rico’s largest freshwater wetland, offering unique opportunities for wildlife observation, especially migratory birds and native aquatic species.
Caño Tiburones Nature Reserve, located in the northern coastal region of Puerto Rico, spans approximately 2,800 acres of freshwater wetlands, marshes, and mangrove forests. The reserve is the largest freshwater wetland on the island, playing a vital ecological role in flood control, water purification, and maintaining biodiversity. Its extensive canals and lagoons are home to hundreds of species of birds, fish, reptiles, and amphibians, including the endangered Puerto Rican boa and the West Indian manatee that occasionally visits its waters. Historically, the wetlands have been a crucial resource for local communities, supporting fishing and small-scale agriculture.
Visitors to Caño Tiburones can enjoy birdwatching, particularly during the winter migration season when the reserve hosts large flocks of herons, egrets, and other waterfowl. Canoeing and kayaking through the winding canals provide an immersive way to explore the reserve’s diverse habitats. While there are few developed hiking trails, guided tours offer insights into the reserve’s ecosystems and cultural heritage. The reserve is also important for scientific research and environmental education, highlighting wetland conservation's importance in a tropical island context. Its remote and often swampy terrain requires visitors to be prepared and mindful of seasonal weather conditions and local regulations to protect this sensitive environment.
