Monteverde, one of the world’s most celebrated wildlife refuges, also attracts humans in search of their own wild lives. Adrenaline bursts can be administered according to each visitor’s tastes. Airborne adventures include 2,460-foot zip-line rides with fantastic canyon and canopy views. The park also offers tree climbing, hikes along suspension bridges over old- and new-growth forests (in the company of expert guides), and the chance to get close to tarantulas, lizards, boas, and Costa Rica’s red-eyed frogs. Catch your breath—and breathtaking views of the jungle canopy—aboard cable-borne gondolas.
