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.

John Muir Trail
Wikipedia says: The official length of the JMT, as stated by the United States Geological Survey (USGS), is 211 miles (340 km). From its northern terminus in Yosemite Valley, the trail runs northeast, passing south of Half Dome and then on to Tuolumne Meadows. From Tuolumne Meadows the trail turns south, running parallel to the main range of the Sierra Nevada, through Yosemite National Park, Inyo and Sierra national forests (including the John Muir and Ansel Adams wilderness areas), passing through Devils Postpile National Monument, through Kings Canyon National Park, and ending on Mount Whitney in Sequoia National Park. From the southern terminus of the John Muir Trail at the summit of Mount Whitney, an additional 11-mile (18 km) hike on the Mount Whitney Trail is required to reach the nearest trailhead at Whitney Portal, thus making an end-to-end traverse of the trail effectively 220 miles (350 km).
