3. Arenal Volcano Park, Costa Rica

The zip line at Costa Rica's Arenal Volcano Park is a ride like no other.

The Sky Trek is part of the larger program that includes a Sky Walk along bridges in the jungle and a ride in an open-air gondola that takes you into the treetops so you can zip back down. Arenal Volcano Park, Costa Rica

6. Flight of the Gibbon – Thailand

With locations in Chiang Mai, Bangkok and Pattaya, you can zip your way through the country with these tours. Instead of one long ride, the tour here offers zip lining between treetop platforms and rappelling descents. They also offer river rafting, mountain biking and rock climbing. Perhaps the best part about these tours is the fact that the money you pay to experience the jungles of Thailand will go towards protecting them, since a profit of the tours goes to protecting the endangered gibbon and the rain forests. Flight of the Gibbon – Thailand
