Plumas-Eureka State Park, Mining museum and state park in Plumas County, California.

Plumas-Eureka State Park lies in the Sierra Nevada and Cascade Range in Plumas County, about 5 miles (8 km) west of Blairsden on County Road A-14 and 60 miles (97 km) north of Lake Tahoe. The park protects the mid-19th-century Gold Rush mining area, including the Mohawk Stamp Mill, a five-stamp mill, stables, a blacksmith shop, the mine office, and the Moriarity House. A California Historical Landmark marker honors Jamison City, Eureka Mills, Johnstown, and the Eureka Mine.

The park preserves the mid-19th-century Gold Rush mining area of Eureka Mills and Jamison City. A California Historical Landmark marker commemorates these settlements and the Eureka Mine. Surviving structures include the Mohawk Stamp Mill, a Bushman five-stamp mill, stables, a blacksmith shop, the mine office, a miner's bunkhouse now serving as a museum, and the Moriarity House.

Gold Discovery Days, a living-history weekend held each July in the park, features mining-era demonstrations and hands-on activities. The event is staged among the surviving structures of the historic mining area, including the Mohawk Stamp Mill and the miner's bunkhouse that now serves as a museum.

The park offers camping accommodations for both tent and RV campers spread throughout the grounds. Visitors should expect seasonal variations in accessibility, as snow may affect higher elevation areas and roads during winter months.

Eureka Peak, once called Gold Mountain, hosted some of North America's first organized ski races. The National Longboard Championship has run at the Eureka Ski Bowl since 1993 and is described as the longest-running ski race since 1911.
