Climbing 2,700 vertical feet in 5 miles, McCallister Gulch is a mildly steep trail that climbs the west side of Resolution Mountain, just north of the historic Camp Hale. Camp Hale was a WW-II facility that trained U.S. Army soldiers in mountain warfare. Those soldiers went on to form the famed 10th Mountain Division.
This trail offers outstanding views of the Gore Range to the south and the Sawatch Range to the north, including clear views of the Mount of the Holy Cross.
