We camped in Plymouth, CA at the 49er Campground and traveled daily to visit the Gold Country towns. This area is the foothills (west) of the Sierra Nevadas, where gold was discovered at Sutter Mill.
Our first visit was the cities of Amador and Sutter, with Sutter Creek running through town. The buildings were restored and the shopping was fun. We took an underground mine tour that was very interesting and chilly. Our tour guide was a real miner with lots of tails to tell.
