We pulled in around 1am. Saw the signs for "no overnight parking", but got out and read the signs near the bathroom. They state that you can stay up to 8 hours in a 24 hour period. We got settled and had no issues. In fact, in the morning, the attendant, Mike, told us about the six iron wells up river causing the red colour in the stream and other facts about the area. He was very informative and nice. Highly recommend this spot if you need a rest on 101.
