Hidden back in the foothills of the Sierra Nevada's is an old gold mine. There is lots of old equipment and some building to see and explore. Volunteers have come to the site and worked on signs and such to make it a nice place to walk around. There is a picnic around for having a meal while you are there. The hike to the mine is all up hill and the entrance has been mostly filled in. But the view from up there is beautiful. You are going to want a vehicle with some clearance. The road goes all the way back, so the only hiking is around the mine area. We have gone twice with family and both times my kids had a blast. It is a fun and interesting piece of history.
