Uhlhorn Trailhead is a recreation site adjacent to Big Snowy Mountains, southeast of Lewistown, Montana. The site was created by the BLM with cooperation of the Forest Service and the Judith Basin Back Country Horsemen group. The trailhead offers access to a hiking/horseback riding trail that connects to Forest Service trails that lead to Halfmoon Pass and Crystal Lake. A large parking lot, a vault toilet, and hitching posts are available at the trailhead.
