Winter Fat Biking is a refreshing alternative to traditional winter activities that many people can enjoy. Winter Fat biking is allowed on groomed motorized OSV trails and non-motorized winter trails at Obsidian Dome and Shady Rest. Only Purpose-built fat bikes with 3.8” wide tires or wider with a recommended tire pressure of 6-10 PSI are allowed on trails. If you leave a rut deeper than 2 inches or can’t ride in a straight line... it’s too soft to ride! Firm snow is the best snow. Conditions may deteriorate over the course of the day. Beware of icy patches. Get out and enjoy winter on two wheels!
