Overview

Roundtrip mileage:6.75 miles
Cumulative elevation gain:2,200 feet

This pleasant outing starts at 8,960 feet of elevation and rises upstream through the outcrop-highlighted Threemile Creek drainage. The trail crosses the creek several times on rustic log foot bridges and brings the hiker to a broad meadow at about 10,500 feet. From there, the hiker navigates up the northeast slope of Spearhead Mountain toward the peaceful, timbered summit.

  • Leaving the parking area at 8,960 feet of elevation, follow the Threemile Creek Trail first north along a ledge to the Wilderness boundary.

  • The Threemile Creek Trail heads north-northeast through a narrow valley for approximately two miles.

  • At approximately mile two, the Threemile Creek Trail turns almost due-east as Kataka Mountain begins to loom to the hiker’s north.

  • After about another mile of on-trail travel, the hiker will reach a broad meadow near the junction of the northern and southern upper drainages that converge to form Threemile Creek.

  • Leave the trail, entering the trees, and begin ascending more steeply up a barely discernable ridgelet, the northeast slope of Spearhead Mountain.

  • Upon leveling out on the summit plateau of Spearhead Mountain, several rock outcroppings provide different vantage points for enjoying the surrounding peaks.

  • The actual summit of Spearhead Mountain is the furthest outcrop to the west. It is dotted with a lone pine and a summit register placed in 1976 by the Brown Bear Mountaineering Club.
