Some zip line parks are one-and-done—you arrive, sit for orientation, take a single (if exhilarating) ride, and get back in the car. Not so at Sky Safari, located at St. Kitts’ Wingfield Estate. Here, you start with a training run on a short zip line, then head into the jungle for the main attractions: four more lines that run over the lush canopy of slumbering stratovolcano Mount Liamuiga. The first three lines, named The Boss, Mango Tango, and Brimstone Blast, measure up to 1,400 feet long, while the fourth is a dual zip line that crosses over a river and ends near the ruins of a historic sugar plantation. As you soar, you’ll reach heights of 250 feet and thrilling speeds of up to 40 miles per hour.
