The Rubicon Trail is a 22-mile-long route, part road and part 4x4 trail, located in the Sierra Nevada of the western United States, due west of Lake Tahoe and about 80 miles (130 km) east of Sacramento.
The western maintained section of the route is called the Wentworth Springs Road; it begins in Georgetown, California, a hamlet in California's Gold Country. The road continues from its intersection with State Route 193 toward Wentworth Springs, where the trailhead for the unmaintained portion of the route exists adjacent to Loon Lake. The trail portion of the route is about 12 miles (19 km) long and passes in part through the Eldorado National Forest as well as the Tahoe National Forest and the Lake Tahoe Basin Management Unit. The eastern maintained portion of the trail is called the McKinney Rubicon Springs Road, and leads to Lake Tahoe.
