Copper Lake & Lake Malachite - 10.2 Miles Round-Trip

The West Fork Foss River Trail reaches deep into the highest concentration of lakes in the Alpine Lakes Wilderness between Highway 2 and I-90. Lake Malachite and Copper Lake lie in close proximity off the main trail artery, 4.95 miles and 5.1 miles from the trailhead (respectively).

The lakes are ideal destinations for day hikers, with great camping options at each for staging longer trips through this highlight-rich valley:

The trail enters the Alpine Lakes Wilderness and joins the West Fork Foss at .4 miles. Views open to Shoestring Falls and the rocky ridge of Malachite Peak as it winds past debris from a 2006 flood to a new footbridge over the river (.98 miles : 1,675’).

Once over the trail rises gently among towering hemlock and cedar to Trout Lake (1.85 miles : 1,920’). The day use area here includes a natural swimming beach, established campsites and privy.

The trail arcs west past Trout Lake along Copper Creek to Upper Copper Falls (2.4 miles: 2,264’), then begins a 2 mile climb on switchbacks toward the bench holding Malachite and Copper Lakes. It gains 1500' between Trout and Copper Lake on this long, methodical climb.

The trail switchbacks along the creek through open areas of fireweed and vine maple to Malachite Falls at the headwall below Malachite and Copper lakes. It crosses under some granite crags and fords a stream at 4.0 miles (3,305’).

Travel moderates after crossing a creek at 4.2 miles and passes through yellow cedar and mountain hemlock to the Lake Malachite junction (4.75 miles : 3.751’). A short, steep spur breaks .2 miles west to Lake Malachite (3,990’).

The main trail keeps straight across an outlet creek on flat stones to the north end of Copper Lake (5.1 miles: 3.780’). The trail continues 2.9 miles to Big Heart Lake at the head of the valley.

Comments

"Well marked trail, but more difficult than we'd imagined, most likely due to it being yet another hot summer day (92 in the sun, 84 in the shade; yes, I had a thermometer w/ me!). Very rocky and narrow path. Lots of wildflowers surrounded us and many butterflies encouraged us on our trek. The last .2 mile to Malachite was esp difficult for us (we are 50 and 56 yo) but the 2 hours spent swimming, reading and lounging at this absolutely gorgeous lake made the effort worth it. And, no one else was there. In summary: a great/hard work out and a stunning, truly magnificent lake as a reward for your efforts."
