Mineral Creek Trail #1331


The Mineral Creek Trail begins at Forest Road 46 and ends at Trail #2000.6. This is a hiker only trail that accesses the Pacific Crest Trail and Alpine Lakes Wilderness.

From the trailhead, the trail runs down to a crossing of the Kachess River. From there it climbs 0.25 mile to the junction with Little Kachess Trail 1312. 1331 turns right and goes up through old-growth forest on an old mining road. The trail passes an old mine (end of the mining road) site at approximately 1.3 miles and soon after crosses Mineral Creek. Just past the crossing is the wilderness boundary. The trail runs above the creek and passes through several large brushy avalanche clearings and patches of forest. At approximately 4 miles, the trail crosses a creek and begins to climb steeply through forest towards Upper Park Lake. Near the lake, the trail levels off in an area of trees, meadows, and rolling hills called Park Lakes Basin (no campfires are allowed in the basin) and continues upward towards its junction with the Pacific Crest Trail.
