Trekking, biking, horseback riding, kayaking, ziplining. Costa Rica really is the "Adventure Capital of the Americas." Thrill-seekers will find more than enough to keep themselves busy over this trip’s 13 action-packed days. After landing in San José, embark on four days of exploration around Monteverde and Arenal Volcano. Raft down the mighty Pacuare River before crossing over to our remote rainforest lodge, surrounded on all sides by the thick, enveloping jungle. End the journey by heading down to the beach at Puerto Viejo. Phew! Tired yet? No? Time to book! Hotels (10 nts), jungle lodge (2 nts).
