If zip lining is your thing, you’ll love Toro Verde. This ecological adventure park in Puerto Rico has more miles of cable than any other park in the world. It also has the world’s longest single run zip-line, La Bestia (The Beast). Aptly named, you are strapped to a special harness so that you “fly” superwoman-style over the valley almost a mile in length and reach speeds of up to 60mph. Still feeling brave? Try the other 8 zip lines along with the suspension bridges and rappelling to the waterfalls.
