Tahoe Rim Trail?
Wikipedia says: The Tahoe Rim Trail is a 165-mile (266 km) long-distance hiking trail which forms a loop around Lake Tahoe in the Sierra Nevada and Carson ranges of California and Nevada in the United States. The trail ranges in elevation from 6,240 feet (1,900 m) at the outlet of Lake Tahoe to 10,338 feet (3,151 m) at Relay Peak in Nevada. About 50 miles (80 km) of trail above the lake's west shore are also part of the much longer Pacific Crest Trail.
The idea of a crest trail around Lake Tahoe was first proposed in 1978 by Glenn Hampton, a recreation officer of the Lake Tahoe Basin Management Unit (LTBMU) of the U.S. Forest Service. The trail was completed in September 2001, almost entirely through volunteer effort. The trail currently exists mostly on land managed by the LTBMU and Lake Tahoe-Nevada State Park, with shorter segments in the Tahoe National Forest and the Carson Ranger District of the Humboldt-Toiyabe National Forest.
The main hiking season is usually from July through September, though lingering snow patches may sometimes be found into August of high snow years. The trail is open year-round, but is not marked for winter use. The climate is typical of the Sierras, with severe storms during the winter and almost no precipitation falling in the summer.
