What to know
Rent a fat bike to try it first — shops in the mountain towns have them. Ride groomed trails when the snow is soft (riding ruts into a soft trail is bad etiquette), dress in breathable layers, and lower your tire pressure for grip. Season runs roughly December through March. Gear up with our gear guides.
