Crystal Peak is a 7,780-foot mountain in the Raft River Mountains of northwestern Utah, in Box Elder County. Although it lies within the area designated as Sawtooth National Forest, the U.S. Forest Service does not own or manage the land on or around the summit. The peak stands about 7.1 miles east of Bull Mountain, and its name comes from nearby Crystal Spring. With no roads or trails leading to the summit, it remains relatively isolated despite being within a national forest boundary.
