The Tahoe Rim Trail (TRT) is a 170-mile (274 km) long-distance hiking trail that forms a loop around the Lake Tahoe Basin in the Sierra Nevada and ranges of Nevada and California in the United States.

[2] 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 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 climate is typical of the Sierra Nevada, with severe storms during the winter and almost no precipitation falling in the summer.

Hikers must obtain permits before entering the very popular Desolation Wilderness area southwest of the lake.
