Located close to the La Frotuna waterfall and about three kilometers (two miles) from downtown La Fortuna, the Arenal Oasis Eco Lodge and Wildlife Refuge is run by a local Costa Rican family dedicated to conservation and sustainable tourism. There are a bunch of different nature tours available, in which experts will help provide you with extraordinary experiences with Costa Rica’s famous wilfelife.
