It’s a combination of blue and green trails that takes you from the very top of killington to the Bear mountain lift. The predominant trail in the video is a green called Bear Cub, but they take Blue Haven (blue), Bear Trax (blue and green), and Bear Cub (green). Killington also has a similar route called Peak to Creek that’s longer and just as easy, which takes you out to route 4 and the Skyeship gondola through Great Eastern.
This is a nice video of the long run! If you want to add music, RU-vid offers some royalty free music options. I added music to my snowboarding videos from Killington.
