When in Costa Rica … you zipline! We were so pleased with our choice of the Original Canopy Tour. It might not be the most adrenaline-focused zipline tour available (I believe others are faster and have longer ziplines), BUT you get to explore a lot of the canopy, and it includes a(n optional) Tarzan swing, a rappel and a neat climb up the hollowed-out trunk of a tree. Our guides were amazing - very experienced and made us feel comfortable and safe the entire time. The only con is that we booked on TripAdvisor the day before, and no one picked us up the next day. When we called the office, someone came right away and we ended up getting a private tour, so it worked out! But if you book less than 24 hours in advance, you may want to confirm directly with the company to make sure they saw your reservation.
