The Rubicon Trail is widely recognized as the premier OHV route in the United States — a 22-mile route in California's Sierra Nevada west of Lake Tahoe combining 10 miles of maintained Wentworth Springs Road from Georgetown with 12 miles of unmaintained granite rock trail in El Dorado, Tahoe, and Lake Tahoe Basin national forests. The technical section runs across exposed granite slabs at 6,000 to 7,000 feet, with named obstacles like Big Sluice, Little Sluice, and Cadillac Hill that demand serious vehicle preparation.

Most groups take two to three days to traverse the technical portion, camping along the way at Loon Lake, Buck Island Lake, or Rubicon Springs. Modified vehicles with locking differentials, ample body protection, and a skilled driver typically clear the trail without major damage. Stock high-clearance 4WDs can complete it with experienced spotters but emerge with significant scratches and dings.

Getting Oriented

The Rubicon crosses three national forest units in El Dorado and Placer counties, west of Lake Tahoe and 80 miles east of Sacramento. Georgetown anchors the western end with the Georgetown Ranger District office of El Dorado National Forest. The eastern terminus connects to Tahoe Basin via the Lake Tahoe Basin Management Unit. The Rubicon takes its name from the Rubicon River, which the trail parallels for much of its length.

The trail is jointly managed by the Forest Service (federal land) and El Dorado County (the county portion has a maintenance agreement). Annual events include the Jeepers Jamboree, a 70-year tradition where hundreds of vehicles and thousands of attendees gather at Rubicon Springs.

Trail Overview

From Georgetown, drive east on Wentworth Springs Road. The first 30 miles are paved or graded gravel through gold-country foothills. The pavement ends at Wentworth Springs near Loon Lake. The technical 12-mile section starts at the Loon Lake trailhead.

The trail climbs through Big Sluice — a series of granite ledges and boulder fields that require precise line choice — to Spider Lake. Past Spider, Little Sluice presents another technical climb. The middle section runs through Buck Island Lake, then climbs to the Rubicon Springs area where most groups overnight. The eastern descent runs through Cadillac Hill, the trail's most-famous obstacle: a steep granite-slab descent with multiple step-down ledges.

The trail exits via Wentworth Springs Road on the Tahoe side and connects to State Route 89 north of Tahoma.

Where to Camp

Dispersed camping is allowed throughout the route at unmarked sites with the standard 14-day stay limit. Loon Lake, Spider Lake, Buck Island Lake, and Rubicon Springs are the most popular camp areas. Loon Lake has a developed Forest Service campground with fees. Pack out everything; the trail's high-traffic camp areas accumulate trash quickly.

Tips for a Safe and Enjoyable Trip

Travel late July through September. Snow closes the high-elevation sections most of the year.
This is one of the most demanding 4WD trails in the country. Bring locking differentials, body armor, recovery gear, and a winch.
Travel in two or more vehicles. The trail's remoteness and complexity make solo travel risky.
Plan two to three days. Single-day attempts exhaust drivers and increase damage risk.
An experienced spotter can save thousands in body damage. Hire one if you're new to the trail.
Annual permit may apply for some camping areas; check current rules.
Cell coverage is absent. Carry a satellite messenger.
The trail is part of the El Dorado County maintenance area; help preserve access by following all rules.
Pack out all waste including human waste. The trail has had ongoing waste problems.
Contact the El Dorado National Forest's Georgetown Ranger District at 530-333-4312 for current conditions.

Hazards

Vehicle damage. Almost guaranteed without proper preparation. Bring spare parts.
Brake failures. A common cause of accidents. Inspect brakes before starting.
Lightning. The high-elevation granite attracts thunderstorms.
No cell coverage. Satellite messenger essential.
Wildlife. Black bears in the camp areas. Practice food storage protocols.
High elevation. Sections at 7,000+ feet; visitors from sea level should expect altitude effects.
Crowds during the Jamboree. The annual Jeepers Jamboree fills the trail; either join it or avoid the dates.
Snow. Possible at any time of year above 7,000 feet.
