Stream crossings are common, sometimes requiring rock hopping. The initial climb from the trailhead is steep, and the final ascent to Duck Pass is particularly challenging.

The trail offers spectacular High Sierra scenery. You'll pass a string of crystal-clear alpine lakes, including Skelton Lake and Barney Lake. From the top of Duck Pass, you'll be treated to outstanding panoramic views of Duck Lake, the surrounding lakes basin, and the rugged 11,000-foot peaks of the John Muir Wilderness.
