Duck Lake Trail or Loop is a very nice, moderately challenging hiking trail around Duck Lake (one…read moreof several lakes with that name) in the Carson-Iceberg Wilderness, an appendage of the Stanislaus National Forest in the Sierra Nevada east of Sonora and north of Yosemite.
This is reached by Highway 4 (running across the Sierra Nevada from Stockton to near Markleeville, via Ebbetts Pass).
The trailhead is at the Silver Valley Campground on the eastern side of Lake Alpine. If coming from the west, this is reached via a small road to the right off of Highway 4 just east of Lake Alpine, which is just east of Bear Valley. The small access road ends at the campground and just before the campground is the trail head. As of September 2023, the trailhead was not immediately obvious because of damage to the trees and sign. There is limited parking on the side of the road.
In its full length includes a roughly 4-mile loop. There are links to other trails as well. Much of the trail is easy going physically, but there are some significant uphill or downhill parts, mostly at the beginning and end; around the lake itself the terrain is mostly easy going, with some woodland, meadows, and granite outcroppings. This trail could take about 2 hours to complete, more or less, depending on a number of factors. For us, the biggest thing to slow us down was the fact that the trail, though obvious in the start/end, tends to become vague and harder to identify in many sections around the lake. It is not especially well cleared for much of that, and mostly one must follow it by being careful about the direction, orienting via the lake, looking for trail blazes, and, especially in the hard granite areas, stone markers which hikers put up. This is a common issue, apparently.
Otherwise, it is a very nice hike, and the lake is lovely. There is an old cabin next to the lake, and some pasture areas with cattle since livestock grazing is permitted int the Wilderness. It is peaceful and we only encountered three other groups of people on the entire hike when there in September 2023.
