Nestled in the Sierra Nevada foothills of Grass Valley, Empire Mine State Historic Park preserves one of California’s oldest, largest, and richest hard-rock gold mines. Operating from 1850 to 1956, this 853-acre historic park offers visitors a fascinating window into the Gold Rush era and the industrial mining that followed.

What Makes It Special

The Empire Mine produced an astounding 5.8 million ounces of gold over its century of operation. Today, visitors can peer down the original mine shaft—which plunges nearly a mile deep—and explore 367 miles of underground tunnels through exhibits and guided tours. The beautifully restored Bourn Cottage, an English manor-style home built for mine owner William Bourn Jr., showcases the wealth generated by California’s gold industry.

Key Activities

Guided mine yard tours reveal the massive headframe, stamp mills, and machine shops that powered operations. Miles of forested trails wind through the property, perfect for hiking, mountain biking, and horseback riding. The restored gardens surrounding Bourn Cottage bloom spectacularly in spring.

Best Time to Visit

Spring (April-May) brings wildflowers and mild temperatures ideal for hiking. Fall offers golden foliage and fewer crowds. Summer weekends feature living history programs with costumed interpreters.

With a stellar 4.8-star rating from over 2,000 visitors, Empire Mine delivers an authentic, educational experience. Plan 2-3 hours to fully explore the grounds, buildings, and trails. The visitor center provides excellent context before you begin.
