We stayed a Friday night in late July. Got a FF site at 3 PM and the place never filled. There are two campgrounds (east & west). The eastern one seemed nicer with more access to River.

Loads of trees and shade - hard to get solar power going. One water spigot near host and nice vault toilets throughout.

Overall very quiet and natural. There is a train across the River that come thru several times a day for a few minutes each pass but not at night. Some nice folks and hosts were great.
