Spearhead Mountain is a delightful, ranked 11er quite close to the Denver metro area. While the summit is well timbered, the summit area is studded with rocky outcrops around the mountain, providing high-country views in most directions. Contained within the Mount Evans Wilderness, the summit of Spearhead Mountain provides views of higher peaks both near and far. The standard (Threemile Creek) route to the summit of Spearhead involves mostly on-trail travel with a short off-trail climb, making this mountain a worthy goal for beginner to intermediate bushwackers.

Getting There

Spearhead Mountain Area MapSpearhead Mountain Area Map

Spearhead Mountain is located in northeastern Park County, about four miles as the raven flies due north of the town of Grant on Hwy 285. The most logical and direct access to Spearhead Mountain is via Guanalla Pass Road, which runs twenty-two miles between Georgetown (Clear Creek Valley) to the north and Grant (Geneva Creek Valley) to the south. This road further links Interstate 70 to the north and U.S. Highway 285 to the south. Traveling Guanella Pass road from end-to-end requires about one hour of driving time and the route, while only partially paved, is suitable for passenger cars (no 4x4 required).

Backcountry Camping
The upper Threemile Creek area would make for lovely backcountry camping, though be forewarned that proximity of this area to Denver, in general, and to Guanella Pass, in particular, could mean you will “enjoy” plenty of company. There is at least one established backcountry site in this area, a pleasant flat area, free of willows, near where the northern and southern upper drainages come together to form Threemile Creek.

Weather & Seasons

Thanks in part to private property holdings along the lower, southern reaches of Guanella Pass road that require winter access, Spearhead Mountain is accessible year round.

Summer: The crowds from nearby Denver may border on unbearable for the hiker accustomed to solitude. While the summit of Spearhead Mountain may see very few visitors, the feeder trails will be full of day-tripping visitors and weekend campers.
Winter: The steep slopes along the approach to Spearhead Mountain could be dangerous in moderate, high or extreme avalanche danger. Use caution and exercise sound judgment when traveling in this area in snow season.
