I really enjoyed camping at Shotwell. To get there, you have to drive about 2 miles down a road away from the welcome center. This is nice because it is quiet from traffic from cars. Each campsite is fairly big and far enough away from each other so you feel like you have your own space. Some of the sites had a platform to set up your tent on which is nice, especially if you are going after it recently rained. Our site had a picnic table and fire ring. There was a communal bathroom which was fairly well maintained and a large dumpster near the front of the site to drop off your trash. They did have a cabin-like option but I did not stay in it and do not know much about renting those.
Roads are a bit rocky but the site itself is quiet.
