The Desafio MAMBO COMBO Canyoning & Rafting adventure is one of the most-popular full-day tours in Costa Rica. There are very few places in the world where you can rappel down incredible waterfalls and raft down an exciting jungle river. Start by doing TripAdvisor's top experience Lost Canyon Adventures canyoning and then head out to raft the fun Class 2 and 3 Balsa River. And to top it all off, you get an all-you-can-eat all-natural, tropical buffet lunch at Desafio's Hunters and Gatherers restaurant right next to the famous El Salto swimming hole of the Río Fortuna.
