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.

It can get confusing. Trails are awesone. Vistor center doesn't open till 10 a.m.

Lots to see along the trails.

Nice wide trail, best to walk on weekdays. It gets a bit busy on weekends.

Nice little hike if you're visiting the mine. Kid friendly.

Great trail to take the kids on! Many pieces of mining history along the trail to explore.

Great trail for walking. Watch out for horse droppings!

Great in-town hike with varied terrain and loop choices that ring the park grounds. Used by locals daily. You share the trail with fellow friendly hikers, bikers, horse riders, and dogs on leash. Return so you can experience the historic state park gold rush learning inside the gate.

Great place for a walk with the kids and dog. Or a trail run.

Love this place!

Nice morning hike.

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

What a great day. Hiked with good friends after enjoying a wonderful lunch at one of the many shaded picnic tables. I will definitely be doing this one again.
Has just enough traffic so a lone hiker will feel safe. Park has easy to follow signs and more than one trail to choose from.
A definite 5 rating!!!!

Great spot. Love being around Empire Mine.

Great for families and dogs that love to be leashed. Grateful they have preserved this piece of history and that it has geocaches here. I would call this a neighborhood park more than a place to hike.

This was a wonderful hike for our family. We will have to go again and see if there is another way to end the 5 mile loop. The last stretch was next to the busy road, which it why I only gave it a 4 instead of 5, but the rest of the trail was wonderful.

Very nice moderate walk

Beautiful loop. You can see the mine grounds, but can't enter without a fee - although the museum/visitors center is free. Some steep climbs.

Great ride with some good uphill climbs & some great technical riding from beginner to advanced riders

I took my over 50's ladies group up to hike a couple of the trails. We all made it okay but you I have to take into consideration you most definitely are hiking up and down a mountain. The paths are well used/maintained but there is a steep grade. The trails are used by lots of people so they are busy so not a whole lot of peace and quiet. It's nice that there are state maintained restrooms at the mine. Poison oak is on the sides of the trails so watch the kiddos and pets. We will do this trail again.

The Mansion and the grounds are very cool. Multiple loops for hiking as well.

I go there all of the time. There are a number of different length trails. The woods are quiet yet close to civilization. The mining museum and mansion are well worth seeing.

This is an awesome trail, they have done a lot of improvements, it's quiet and woodsy, feels like you're in the forest yet you're in the middle of town. The convenience to get to makes it a regular place for me to jog, bike, hike and stroll with my city visitors! I have logged as much as 6 miles or you can do as little as 1,your choice. Include union Hill and you can do even more. The hill climbing helps give great workout in short amount of time, or avoid the hills and just enjoy the flatter trails. Dogs love it, horses are enjoyable to pass along the way. If you go in summer, start early.

Nice short trails to take the dog when I don't have a lot of time. Some beautiful buildings and landscaping on the grounds. I had previously only hiked the trails but never visited the paid area, definitely worth the trip and so cool that its so dog friendly. You don't see that often in a state park
