Rio Celeste and Guanacaste's rainforest are the focus of this private full-day tour from Playa Flamingo, with a guided walk through primary and secondary forest to the waterfall, wildlife viewing at a local sanctuary, and lunch before a visit to Mariposario Rio Celeste. Look for birds, frogs, sloths, monkeys, and other species while your guide shares information about Guanacaste and Costa Rica. A coffee-and-chocolate tasting stop follows on the return.
