The 300,000-acre Hatcher Pass Management Area provides options for snowmobilers of all skill levels that includes mountainous terrain backcountry trails that branch into side valleys, creek draws and onto broad ridges that require at least a moderate level of experience. Plus there are more than 30 miles of groomed trails that are ideal for even novice and beginning snowmobilers. The east side of the pass is known for many narrow valleys that require riders to stay on marked trails. The west side has broader valleys and glacier-smoothed alpine areas that invite exploration.
