Empire Mine State Historic Park in Grass Valley is the site of one of the oldest, largest, deepest, longest and richest gold mines in California. In existence for more than 100 years, the mine produced 5.6 million ounces of gold before it closed in 1956. (5.6 million ounces of gold is equivalent to a box seven feet long, seven feet high, and seven feet deep filled with gold.) The park contains many of the mines buildings, the owner's home and restored gardens, as well as the entrance to 367 miles of abandoned and flooded mine shafts. The park consists of forested backcountry and eight miles of trails.

Good morning hike. Easy to navigate. Worked up a nice sweat.

My whole family loved it. Our little army ranges in age from 8 to 40 years old. Easy and fun for all.

Right next to my house and one of my regular hike/walks. Lot's of little off shoots. My doggie Chloe always loved it. ♡

Hardrock trail started out nice but the last mile is along the main road, no bueno.

It's was fun lot of people using the trail, not to hard of a walk
