Trail guide
Fox Lake is a roughly 9-mile out-and-back from the Clarks Fork trailhead. The route follows the approach toward Kersey Lake, continues on Trail #567, then takes the Fox Lake branch to shore. Allow about five hours. The mileage counts both directions; the map line traces the way out once. The long distance and 8,000-foot altitude shape the effort more than a steep climb.
The walk begins with a wooden bridge over the Clarks Fork Yellowstone River, then follows the canyon corridor toward Kersey Lake. A calmer, wider reach of water appears about half a mile along. Continue past the Kersey area on Trail #567; the Fox Lake branch leaves roughly a quarter-mile before the lake.
At about 8,085 feet, Fox Lake covers 111 acres. Brook and rainbow trout are common, while Arctic grayling are reported rarely. Small campsites are reported at the north end, where firewood can be difficult to find.
