Within driving distance from Volcano Arenal, this tree house is surrounded by mineral-rich, natural hot springs. The tree house sits in 35 acres of surrounding rainforest filled with two-toed sloths, iguanas, capuchin and mantled howler monkeys, tree frogs, toucans, hummingbirds, and butterflies. An afternoon on the balcony observing the sights and sounds of the rainforest canopy sounds like a dream!
