Visit The Sky Walk (Costa Rica ). It is a well-thought-out combination of suspension bridges and walking trails through the Monteverde rainforest. These bridges span canyons and drainages, and bring visitors face to face with the upper level of the forest canopy. There are six bridges in total, the longest of which spans some 984 ft (300 m). The trails extend for slightly over a mile and a half (2.5 km), making this tour extremely feasible for anyone in moderate shape.
