Located near Costa Rica’s verdant Arenal Volcano National Park, the 3.2-mile Mistico Hanging Bridges Park hiking trail takes visitors through a series of six suspension bridges within a private rainforest reserve. The trail allows for close encounters with some of the country’s most famous flora and fauna, including red-eyed tree frogs, boa constrictors, and more than 300 species of birds. The tour can be self guided, but you’ll want to go with a guide. The nearby resort Nayara Springs offers some of the area’s best private tours, where a naturalist will help you interpret the different plant and animal species along the way.
