Beautiful spot to camp by the upper Sacramento River.

Beautiful scenery... however... the Grounds Host ruined my family's experience by walking up my car at 9pm at night and began hitting the hood of my car with his cain/garbage graber and began yelling "You can't park here!" When I walked up to him asking him who he was, and why he was hitting my car, he yelled that he was going to call the cops and left...we waited for the cops to come and they never showed. He left 3 large scratches on my hood. We were not being loud, we were respectful, but most of all, we were shocked by the Grounds Host's actions. Im not sure if he was drunk or on drugs but I dont see how someone can get so mad about a parked car (in a spot that looks like a parking spot. See pics)! The next morning I was talking to other fellow campers and was told the the day prior, the Grounds Host was going to each campground demanding they give him the money for the camp site and not to put it in the green drop box! Little suspicious if you ask me!

Excellent small camp ground near Shasta lake on the American River. Trains from time to time and stunning views. Clean campsites and it was fairly inexpensive.

Sweet little spot for overnight camping on a road trip. One squatter in the back. Nice views on the historical trail. Good fishing! Train blows whistle every time it passes, day or night; otherwise I’d give it 4 ⭐️.
