The Terraba Sierpe National Wetlands encompass and area of 66,850 acres of land and water; visitors might get a glimpse of reptiles such as iguanas, turtles, caimans and crocodiles. Mammals that are often sighted include three species of monkeys, sloths, coatimundi and raccoons. Sharks use the areas around the mouth of the rivers as a breeding area as the mangroves provide protection for their young. It was recently discovered that Pacific Green Turtles are also using the mangroves as their primary habitats are slowly disappearing. Various bird species such as Scarlett Macaws, trogons, herons, cranes and many others live here as the mangroves are rich in food supply.
