Skate skiing 2.9 miles of groomed trails in Shady rest is an excellent high altitude workout and a great introduction to Nordic skiing in Mammoth Lakes. The moderate terrain includes some modest hills as the trails wind through a beautiful Jeffrey pine and red fir forest, and this experience showcases just about all of the trails in Shady Rest. The groomed winter trails are located right at the entrance to Town and are accessed from the Welcome Center and Ranger Station. This multi-looped experience is shared with a variety of users, including snowshoers and dog walkers, so please be mindful of others and share the trails. Weather permitting, the trails are groomed 5 days a week and are free and open to the public.
