Coloma

Where the Gold Rush started

Coloma is not a generic foothill district. On 24 January 1848, James W. Marshall found gold in the tailrace of a sawmill he was building with John Sutter on the South Fork of the American River. That discovery set off the California Gold Rush. The National Register listing (1966) and National Historic Landmark status cover the mill site, Marshall’s grave, and the surviving townsite — today largely inside Marshall Gold Discovery State Historic Park.

The Nisenan name for the valley is Cullumah. About seventy percent of the present town of Coloma lies inside the state park. Year-round residents number only a few hundred; outside event days the tree-lined streets stay quiet. Highway 49 runs through the middle of the park.

What you see on the ground

The original mill is gone; a full-size replica stands near the discovery site. The Gold Discovery Museum and visitor center hold exhibits on the rush, Native peoples of the valley, immigrant communities, mining methods, and later agriculture. More than twenty historic buildings and exhibits remain: a schoolhouse, Chinese store exhibits, mining equipment (including stamp-mill interpretation), churches, and residential fabric in various conditions. Stone and brick ruins mark buildings that did not survive intact. The Marshall Monument — California’s first historic monument — sits on the ridge overlooking the river canyon and points toward the discovery site.

California State Parks has expanded interpretation beyond a narrow focus on Marshall and the immediate aftermath. Formal tribal consultation, archival work, and family histories now feed exhibits and programs. The Gam Saan Trail (opened 2022) is a 2.5-mile path linking Hennigsen Lotus Park in Lotus with the state park, built with the Locke Foundation and Chinese American community partners to interpret Chinese miners in Coloma.

Getting there and park rules

The park sits on CA-49 between Placerville and Auburn. From US-50 eastbound: Ponderosa exit, left on South Shingle, right on North Shingle (becomes Green Valley then Lotus Road), right on 49 for about a mile into Coloma. From I-80: Elm Ave exit in Auburn, then CA-49 south roughly thirteen miles.

Day-use areas open 8 a.m.–5 p.m. Visitor center and museum 9 a.m.–4 p.m.; mercantile typically 10 a.m.–4 p.m. Closed Thanksgiving and Christmas. Vehicle day-use fee is $10 (state annual passes accepted; prices can change). Dogs on leash are allowed on trails and at the river; not in buildings. Restrooms, drinking water, picnic areas, and parking are on site.

Guided Gold Discovery walking tours (about 45 minutes) run at 11 a.m. and 1 p.m. most days when weather allows — cancelled above about 95°F and on major event days. Gold-panning lessons are offered most days on a first-come basis when temperatures stay below about 100°F; call (530) 622-3470 for current availability. Spring high water can make river-edge activity dangerous; State Parks and partner agencies periodically warn against cold, fast flows. Gold panning, tours, and the blacksmith shop can close for weather, air quality, or staffing.

What this is not

Coloma is a working state park and a small town, not open public land. Private inholdings and residences remain. Do not treat the river corridor or side streets as free camping. Whitewater outfitters operate under concession on the American River; river conditions change with snowmelt and reservoir releases. For current river flow, use the sources State Parks links from the park page rather than old guidebooks.
