I hiked the majority of the trails in one day. The campsites are nice. Only saw a couple people. Besure to get a site on the bluffs just above the river, not above the creek :) There are a couple rock walls good for climbing on the north side of the bluffs. When I went in mid-may, it was very hot! So be prepared.
