Lion's Back is right next to the Hell's Revenge Trail, and is only minutes from town. It's on private property (at least the access is) and they charge $5 to go up it. It's not a part of any trail and can be done at any time, just up it and back down, and it's right next to the road that goes to the Sand Flats Recreation area. If you want to run it, plan on doing Hell's Revenge one day, and do Lion's Back afterwards. Hell's Revenge ends at the bottom of Lion's Back, the end of the trail goes right along the side of Lion's Back.
