I reserved a site fairly last minute after seeing the unusually nice April weather forecast. The check in was seamless and firewood is readily available ($6/bundle when I went). Each site has a picnic table and fire pit with a cooking grate. I ended up selecting a site next to the river and had a cool access point directly from my site to sit on a rock riverside. There didn’t seem to be any obvious access point into the river itself but it was too cold to go in anyways. The sites next to the river don’t have much for shade but other sites seemed to have better coverage. The sites are quite close to one another and if the campground was fully reserved you wouldn’t have much privacy at your sites.
The main park hiking trail starts a mile ish away from the campground. Beware there is NO SHADE on the trail. The quarry is worth the adventure!
