Off the Grid Mountain Adventures Off the Grid Mountain Adventures features one of the longest zip lines in the country, at nearly 3000 feet long, the length of 10 football fields, and close to 300 feet above the canyon floor, reaching speeds up to 60 miles per hour. Those who are competitive will enjoy the dual zip line where you can race your friends and family. Unlike most zip lines where the zipper controls their speed and safety, our highly trained staff does the braking for you, making your experience safer and a lot more fun. We also offer a ride to the top of the mountain in a Hagglund, which is an incredible military transport vehicle imported from Sweden. It’s designed to take troops where no other vehicle could, and Off the Grid Mountain Adventures is the only place in the country to experience one.
