I've never seen a launch on the No. Shore road of the Quinault. There is a launch just below the bridge on So. Shore road. The only takeout I can think of is at the lake. You would have to row over to the Rain Forest resort. They don't have a ramp from what I could tell. I saw three guys dragging their boat over the grass at waters edge to their trailer.
The Quinault can have some nasty water. It changes after every high water. Scout it out before you commit. Tons of wood in the river.
