Home » Videos Black Diamond Course at Sky High Adventure Park Video of a couple challenging themselves on a Black Diamond course at Sky High Adventure Park at Holiday Valley Resort in Ellicottville, NY. Various shots from my GoPro on the course. Friends tried the double black diamond while we did a black diamond. Watch after the end of the video for a glimpse of the rescue. Video by Warren H.
