Several operators run zip-line canopy tours in the forested hills around Manuel Antonio, the most practical way to see the jungle canopy from above. The standard tour runs for two to three hours with a series of platforms connected by cables, dropping through the canopy at speed. Some operators add hanging bridges, rappels, or a Tarzan swing for variety.
Quality varies — choose an operator with certified guides and up-to-date safety equipment. Midori, Titi Canopy, and Midworld are the main established names in the Quepos area. Weight limits typically exclude children under about 20kg. Book through your hotel or directly rather than through street touts near the park entrance.
