Rockpile Trail #3632

The Diamond Rockpile Trail offers a gradual climb into the Diamond Peak Wilderness to an alpine high lakes area. This trail eventually junctions with the Pacific Crest Trail, which is the primary southern climbing route to the peak.

The hiker will pass through forests of mountain hemlock, pacific silver fir, noble fir, western white pine and a scattering of lodgepole pine.

About one mile up the trail from the trailhead, this trail crosses the Diamond Peak Trail. After this crossing, the forest becomes more open and lends views of Diamond Peak and Rockpile Lake.

General Information

General Notes:

Map of Rockpile trail

Close to:  Diamond Peak Trail Area

The meadows are fragile and should be treated  with care.

Long before this area became a designated wilderness, people used to drive cars to Marie Lake, if you look carefully, you will notice that the trail tread west from the Pacific Crest Tral to Marie Lake is actually located on one of the old tire tracks remaining from the early days.

Early season use means ferocious mosquitoes.


Access is from Rockpile Trailhead.
