The Mt. Shasta area is home to the Tri-Forest Snowmobile Trail System, a 260-mile network of signed trails that are frequently groomed for enjoyment by snowmobiles, skiers, snowshoers and dog sleds.  The system includes four parks that have warming huts, restrooms, and loading ramps with plowed roads leading to the parking areas.

Deer Mountain/Chuck Best, Pilgrim Creek, Four Corners and Doorknob parks are within a days ride of each other. Pilgrim Creek Snowmobile Park, outside of McCloud and Deer Mountain Chuck Best, northeast of Weed, are nearest to the City of Mt. Shasta. The system falls over three National Forests – the Klamath, Shasta-Trinity and Modoc.
