All in all, there's those 12 ziplines, 24 platforms, 2 climbing walls, a stop to rappel (upside-down or rightside-up) above the rushing river, Tarzan moments, a swing bridge and some light hiking. It feels awesome while you're getting the grit under your nails and some air time, but bring Icy Hot for the next day, trust us.
Pricing for the Hacienda Guachipelin Adventure tour is $50 per adult/$40 per student/$30 per child, and your hotel can typically arrange the transfers and tours. You don't need to be in American Gladiator shape to go for it, by the way. Every platform has one or two guides to hook you up, answers questions, help out or just calm you down before doing that spider rappel only feet from Class IV rapids.
Pro-tip: While strapping your camera around you works on most parts of the course, don't try to keep your iPhone in your pocket or even bring a bag. Minimal or nothing is the rule here, which is why we don't have any videos of the action. Come prepared with more than a wriststrap, and a plastic baggie in case of rain would be advisable.
Disclosure: We zipped down to Costa Rica as guests of JetBlue and the Costa Rica Tourism Board, but rest assured that all opinions and all photos are completely our own.
