I don't recommend the inside sites in the north loop - sites are super duper close together with only sparse trees in between. It was a noisy night with dogs from a couple different sites barking back and forth at each other into the wee hours, and my campsite neighbors getting in late and bickering as they set up their tent, their headlights facing my tent. 

The map was misleading as to the location of the toilets. I don't like to be immediately adjacent to the bathrooms, and I picked site 97 with this in mind. Unfortunately, there were two buildings with vault toilets (only one indicated on map), one of which I'd estimate was under 50 feet from my tent pad. Luckily, smell wasn't an issue, but it did mean a lot of foot traffic nearby.

The park itself was nice - lovely view of the water from the trails, maps at most trail intersections and the trails were not too busy.
