The Arenal Hanging Bridges, which are part of the Mistico Park, are a series of suspension bridges in the heart of the Arenal Volcano National Park. A three-kilometer (two-mile) trail through a private rainforest reserve includes a total of 16 bridges high above the ground, 10 of which are fixed bridges and 6 of which are hanging. In addition to being a fun activity itself, these bridges also provide unbeatable views of the volcano, the lake, the rainforest and the thousands of plant and animal species that call this ecosystem home. You can either complete the trail on your own or accompanied by one of the park’s expert guides.
