Well if your gunna be there during the weekend, then you can drive up into the gorge instead of having to walk, There maybe some summers up there. You should take a look at mill park, right in the town of siletz. Or the rope slide at ojalla bridge. Lower into tidewater theres strom park and morgan park. Go into coyote rock rv park in the lower siletz, they should be able to point you into some good water also.
