Superfly's backcountry Zip Lines are the only activity that runs year-round. Our Whistler zip line combines the exhilarating feeling of soaring through the air with the breathtaking beauty of Cougar Mountain. Fly above snow-drenched trees, white-capped mountains and reach new heights along our network of trails and boardwalks.  We've designed and custom-built one of the best adventures in the world - Four and Six Line tours feature side-by-side ziplines located in stunning mountain wilderness.
