It was ok.
We camped out at Jenkinson at Sly Park Recreation area. As hikers (not boaters), this wasn't a very impressive area or very impressive campsite. The campsites were shallow (relatively close to the road) and pretty close together (we had some kind of college party across the way, and we could hear pretty much all of it). It was a pretty, tree-covered area that we enjoyed spending time in, and it had all of the basics covered (decent bathrooms, bear boxes, adequate room for cars and tents).
