South Dakota snowmobile trails season

More than 1,500 miles of snowmobile trails exist in South Dakota. Whether you have the need to cross the open prairie east of the Missouri River or lose yourself in the one million acres of ponderosa pine in the Black Hills, South Dakota has it all. Based on trail conditions, the season runs December 15 - March 31 each winter. Trail conditions are available via the Game, Fish and Parks website (linked), the GFP mobile app (SDGFP Outdoors) and Twitter accounts for Black Hills (@BlackHills) and East River (@SDSnowEast) trails.
