The park was nice. We stayed at one of the campsites (#7) designated for those without horses. The condition of the site was fair; it is not particularly large and there is no dedicated tent pad, but the ground was relatively flat and level. The picnic table was in rough shape, as was the fire ring, but both were functional. The bathrooms were standard, with running water. The playground in the middle of the area was nice.
The easy access to the trails along the south shore of the Lake was fantastic. The trails themselves are great; they're rocky, but fun and offer a lot of variety; with easy access to the lake shore.
The campground was not quiet; there were a couple of groups that were a bit rowdy into the overnight hours and one group had a dog that barked for long periods several times through the night. As far as I could tell, there was not a campsite 'host' that stayed on site to reign in such activity.
For $12/night, overall, it was a fair experience, though if returning to that area, we'd probably scout out a different campground.
