On Costa Rica's northern Caribbean coast, Tortuguero National
Park protects one of the last large areas of tropical rainforest in
Central America. The park's beaches are a prime nesting ground for
the endangered green turtles, which come ashore to lay their eggs
between June and October. The slow-moving tropical rivers are home
to river otters and caimans, and other species found here include
three species of monkeys and birds such as toucans and eight
species of parrots.
