This snowmobiling route starts from the staging area at Little Truckee Summit on Highway 89 and travels north on Treasure Mountain Road to Bonita Creek. From there you continue on Nicholas Mill Road up to Bonita Saddle before descending and returning back to the staging area on Forest Road 7. The route follows all groomed trails and sees lots of snowmobiles so other uses are discouraged and wheeled motor vehicles are prohibited during the winter months. Check with the national forest for current snow depths and trail conditions.
