Fodor's Expert Review Tirimbina Rainforest Center

This working biological research station, 17 km (11 miles) southwest of Puerto Viejo, encompasses 750 acres of primary forest and 8 km (5 miles) of trails, some of them traversing hanging bridges at canopy level. Tours introduce you to bats, frogs, and other common but often misunderstood creatures, and show off the beauty of the forest. Reservations are recommended for all activities, and required for the bat, frog, birding, and night tours.
