We just returned from our holiday in Costa Rica, and this was everyone's best experience of the holiday! The guides on this tour (Poncho, Emille, Graiven) were fantastic with the 9 children in our group - very engaging and fun, and extremely safety conscious. They did a super job of explaining and at putting everyone at ease. The tarzan swing, hollow tree, and 1 km long line at the end were fantastic, and such a spectacular view of the rain forest. If you do only one zipline in Costa Rica, make sure it is with Original Canopy Tours!!
