Duck Lake Peak is a stunning mountain summit located northeast of Duck Lake, nestled in the mountains six miles south of Mammoth Lakes, California. The trail to Duck Pass out of Mammoth Lakes is a beautiful route into the Sierra back country. As one crests the pass, pristine Duck Lake lies below and the Silver Divide rises across Cascade Valley to the southwest. Duck Lake Peak (unmarked on most topographic maps, besides an "X") is the highest summit in the immediate vicinity of the lake; and has a prominence of approximately 690'.
The class 2/easy class 3 west slope is easily accessible from the pass above the lake. The chute at the south end of the east face is class 3 from about a mile south of Valentine Lake on the east side.
The peak is visible from Hwy. 395 going south into Mammoth Lakes.
The views from the summit extend as far south as Mt. Hooper above Florence Lake and as far north as Mt. Warren northwest of Mono Lake.
The best time to hike here is late June/early July through October. This area tends to get a lot of snow during the winter.
Appreciation is owed to Windsor Riley (aka Noondueler) who created this page, and who passed away in 2016.
From Duck Pass: From the junction of Hwy. 395 at Mammoth Lakes take Hwy. 203 west into Mammoth Lakes staying to the left as the road goes up beyond the town. As the road goes past Twin Lakes take a left at Lake Mary where the road makes a 180 at 7.8 miles from 395. Continue along the northeast shore of Lake Mary to another left at .6 miles. Go .7 miles to roads end at the trailhead parking for Duck Pass.
Take the Duck Pass trail 3.5 miles to the pass. Get off the trail and continue along the open terrain towards Duck Lake Peak, which is 1.5 miles away. Do not go down to Duck Lake, because that is an elevation loss. Once you get closer to the peak, the terrain gets pretty rocky. It can be hard to follow at times, but just take the path of least resistance. The terrain becomes Class 2/Class 3. Due to the rocky terrain, dogs are not recommended on this hike, unless you leave them with somebody when you go for the summit.
This is the best way to hike Duck Lake Peak. It is 5 miles and 3,000' of elevation gain. You can add Pt. 11,040 above the pass en route to Duck Lake Peak, which offers a tremendous overlook of the area, while only adding 200' of elevation gain and less a quarter mile of hiking distance.
