The Plumas-Eureka State Park is a state park and open air museum in Blairsden, California. It was created to tell the public more about the California Gold Rush period, which took place during the mid-19th century.

Established in 1959, the Plumas-Eureka State Park was designed to provide visitors a glimpse of the point in time that helped shape California to what it is today. It features a historic area, which was once a mining location. Visitors will find here a mining museum (housed in a miner?s bunkhouse), a blacksmith shop, mine office, stables, the Mohawk Stamp Mill, Bushman five-stamp mill, and a ?Moriarity House?.

Visitors of the Plumas-Eureka State Park can also enjoy camping, biking, hiking, picnicking, and fishing at the site.
