The Empire Mine was the richest hard-rock mine in the State of California producing 5.8 million ounces of gold in its operating history of 106 years (1850-1956).

George Roberts, the original discoverer of the gold soon sold his interest and by 1869 William Bourn Sr. owned controlling interest. The Bourn family maintained control of the mine until 1929 when it was sold to Newmont Mining. It ceased operation in 1956.

In 1975 the State purchased the surface property as the Empire Mine State Historic Park. The Park continues to draw thousands of worldwide visitors each year and is noted for its historical tours of the Bourn Cottage, the mineyard and "living history" events.

The park consists of over 800 acres and has eight miles of trails.

• Dogs on leash are allowed in the park and on the trails.
