Zipline Find exhilarating experiences at Yellowstone Aerial Adventures, including the country’s only self-navigating zipline and a 49-adventure course featuring elements as high as fifty feet off the ground. This zipline adventure park was inspired by European aerial adventure courses to combine the popularity and thrill of 3,000 feet of ziplines with 10 stories of complex and challenging acrobatic high ropes elements. They created and patented a self-belay harness system that gives you the freedom to navigate the course at your own pace while always being securely clipped to a static webbing/harness system. The course is a one-of-a-kind highlight opportunity for any Yellowstone vacation!
