Carlos in the Monteverde Visitor Center gave us great recommendations, including this one. We signed up for the Original Canopy Tour that started with a BIG Tarzan swing, followed by 15 zip lines that started small and then got longer and faster. The tour also included a climb up a hollow fig tree, which was fascinating. The guides were very helpful and patient, even with kids as young as 5, although that 5 year old was more brave than me. It was a wonderful way to be up in the trees and view the forest from a different angle. And great value.
