Description
This loop offers all the features of the Mount Judah and Donner Peak tour, superb views and opportunities to carve turns in the backcountry, plus a descent that includes groomed runs at Sugar Bowl Ski Resort. The views include nearby Donner Lake, Mount Lincoln, Crows Nest and Anderson Peak, as well as Castle Peak and much more to the north — even Sierra Buttes on a clear day .
Nearby to the north is Lake Angela and the gentle terrain that is crisscrossed by the following tours:
The loop tour described here actually ends where you park at Donner Ski Ranch, which is located 0.2 mile west of the trailhead. An alternative end point is the Mount Judah Lodge at Sugar Bowl Ski Resort. You may prefer this end because it eliminates skiing "across" the ski resort. But it requires a shuttle vehicle or walking back to Donner Ski Ranch.
Some will remember this area as "wild" before the Mount Judah Lodge and associated ski lifts were built. Many people and organizations, including Snowlands Network's predecessor the Nordic Voice, fought against the ski area expansion because of the visual and social impact it would have on this area through which the Pacific Crest Trail, the Emigrant Trail and the route to Benson Hut passes. In the end development prevailed and now skiers and snowshoers co-exist with the amenities of the ski resort.
Interestingly, Sugar Bowl Ski Resort hated cross-country skiers in the 1970s and early 1980s when cross-country skiing was in its infancy in California. The route under the aerial tramway from Donner Pass Road to the main lodge was marked with signs stating that cross-country skiers were not welcome although this was the most direct route to Benson Hut. Today Sugar Bowl Ski Resort at least accepts cross-country skiers passing through, and is even one of the more popular resorts for telemark skiing.
