Located at the end of Lake Mary Rd. you'll find parking and groomed cross-country ski trails, both for fee-based Tamarack Cross-country Ski Resort, as well as one trail that is free to the public. This is also a main access point to the back-country of the Mammoth Lakes basin for experienced and well-equipped skiers and snowboarders. Avalanche hazards exist. Snowmobiles are welcome on the trails after the cross-country skiing ends, usually by mid-April.
