Check-in says 2pm, but we got there a few hours early and they let us pick a campsite and set up early. Quiet time is at 10pm, so if you're still up just keep the convo low. There is an upper loop, lower loop and riverside campground. I stayed at the upper loop and loved it! From our campsite we were able to walk to the trailhead and do the crags trail all the way to the top of the rocks. Would highly recommend this campground! Many of hikes around, close to a river and a short distance away from Mt Shasta veiws!
