This 12-acre zoo, in the heart of the Panaewa Forest Reserve south of Hilo, is the only outdoor rainforest zoo in the U.S. Some 80 species of animals from rainforests around the globe call Panaewa home, including tigers Tzatziki and Sriracha, as do a couple of “Kona nightingales”—donkeys that escaped decades ago from coffee farms. (Though highway signs still warn of them, virtually all were relocated to California in 2011 during a prolonged drought.) The Panaewa residents enjoy fairly natural, sometimes overgrown settings. Look for cute pygmy goats, capuchin monkeys, and giant anteaters, among other critters. This free attraction includes a covered playground popular with local families.
