is grooming singletrack on snow at Hartman’s! They groom Jack’s, Beck’s, Buddy Bear, Luge, Alonzo’s, and a network of roads by the front side moto park to get riders from the front side over to the Behind the Rocks area and Alonzo’s. Jack’s is a solid gut-buster uphill from the parking lot, but all rideable. You get a nice reprieve on the road before climbing up Beck’s. Hartmans offers the best fat biking in the Gunnison Valley! True singletrack.
