California on the American Discovery Trail

California · Western Terminus

The American Discovery Trail's western terminus is the sand at Limantour Beach in Point Reyes. Westbound, it is the last step of a coast-to-coast walk; eastbound, it is mile zero.

California's 386 miles run from Pacific surf across the Golden Gate Bridge, through the regional parks of the East Bay, over the flat heat of the Central Valley, and up into the Sierra Nevada around Lake Tahoe. The coast is fog and expensive beds, the Bay Area is city walking with almost nowhere legal to camp, the Valley is heat, and the Sierra is snow.

Four Californias in One Crossing

The Coast and the Golden Gate

You start (or finish) on the sand at Limantour Beach, work through Point Reyes and Marin, and cross the Golden Gate Bridge on foot. The paths are established and easy in cool, foggy, marine-layer country, and the planning is lodging and transit in a dense, expensive area rather than wilderness.

The Bay Area Crossing

From the Golden Gate the route runs through the East Bay to Walnut Creek and Antioch on urban trail, road walks, and regional parks, with Mount Diablo standing over the Walnut Creek section. Water and food are everywhere and legal camping is scarce, so each day's problem is where to sleep and how to move through town.

The Central Valley to Sacramento

From Antioch, the trail drops onto the Delta and the river bottoms toward Sacramento: flat, hot, and exposed, with stretches of road. Heat sets the day's mileage more than terrain does. Sacramento has full resupply before the ground starts to climb.

The Sierra Nevada

From Sacramento the route climbs through Auburn and Foresthill into the Sierra, following the historic Western States Trail to French Meadows Reservoir and on to Palisades Tahoe, then joins the Tahoe Rim Trail around the lake to the Nevada line. These are established, signed trails, easier to follow than the open basin and range of Nevada next door. Snow decides when you can walk them.

Timing and the Sierra Snowpack

The Sierra sets California's calendar, and we track it at three snow stations: Tahoe City (6,797 ft), Palisades Tahoe (8,013 ft), and Mount Rose (8,801 ft). For each, we log the date the snowpack drops below three inches in spring and climbs back above it in fall, the practical open-and-close window for the high sections.

Over the last fifteen years, Tahoe City has cleared around April 16, Palisades around May 23, and Mount Rose, the highest and last to open, around June 3. In fall the order reverses: Mount Rose closes first, near November 1, and Palisades follows around November 6. The dependable high-country window runs roughly early June through late October.

Mount Rose has opened as early as May 12 and as late as July 10, two months apart. Check the spring-open and fall-close table below, updated every season, against current conditions before you lock in dates.

Westbound finishers race the first snows to clear the high sections and drop to the coast. Eastbound hikers starting at Limantour usually wait for the Tahoe-area trail to melt out. A dual-directional hiker can also flip to the coast and walk back east, reaching the Sierra and Nevada in a better window.

Water, Resupply, and Logistics

On the coast and through the Bay Area, water and food are easy and legal camping is hard, so plan lodging and transit. In the Central Valley, carry more water than the mileage suggests and time the hot, exposed stretches. In the Sierra, high-country water is reliable, and the constraints become elevation, weather, and food-storage rules around Tahoe.

A hard-sided bear canister is required for every overnight along the entire Tahoe Rim Trail, so any night your camp falls on the TRT portion of the route, you carry one. The Western States Trail sections have no canister requirement.

Sacramento and the Auburn–Foresthill corridor are solid resupply stops. Coastal Marin and the Tahoe-area towns work but cost more than the average trail town.

Every water source, camp, road crossing, and resupply point along the California route is mapped in our Gaia GPS data. When you join Hiking America, we email you an invitation to the California Gaia GPS folder, and the downloadable PDF segment guides live in the members area at the foot of this page.

What a California Crossing Looks Like

386 miles, nine segments, from Pacific surf to the Nevada line. Segment 1 starts on the sand at Limantour Beach and ends on the Golden Gate Bridge. Segments 2 and 3 cross San Francisco and the East Bay under Mount Diablo to the Delta. Segment 4 is the flat, exposed run to Sacramento. Segments 5 and 6 climb into the foothills at Auburn and Foresthill, Segments 7 and 8 follow the Western States Trail to Palisades Tahoe, and Segment 9 is the Tahoe Rim Trail to the Nevada line, bear canister in the pack. 🥾⛰️
