#2 Schweitzer - Off-Piste Rating
Schweitzer's off-piste terrain gets rave reviews from our community. One Snomad user, an expert skier, loves the large bowls that offer plenty of space to carve fresh lines. The backside of the mountain delivers some proper challenges, with Glade-iator being a must-hit on powder days for tree enthusiasts. Advanced riders particularly enjoy the South Bowl's wide-open terrain that transitions into fantastic tree skiing, while the more daring can tackle the Lakeside chutes when feeling particularly sendy. The cat skiing operation also gets a special mention for being "super rad" with incredibly knowledgeable guides who'll help you find the best stashes.

Sun Valley's off-piste terrain gets mixed reviews from our users. While not the deepest powder destination, it still offers some exciting adventures.

The bowls are particularly praised, with Mateo noting they're "great on a powder day." Tree skiing receives special mention, with one expert skier revealing you can "lap untouched powder for days" in the trees since "most skiers stay on groomers." For those willing to explore, there are hidden gems, as Pete cryptically hints: "Come find the deep stuff for yourself."
