The name says it all.  Will surfed this for 14 minutes once, and the only reason he stopped is because he was getting lonely out there.  This is a great place to teach beginners how to surf because the eddy access is great, it's only in a class II rapid, there's a big recovery pool below it, it's roadside, and the surfing is easy. Couch Wave is wide, you can stack several surfers on there at once.

This wave actually has two optimal flows, depending on what you're looking for.  At low and high flows you can actually do a spin or two and backsurf.  At "optimal" flows it's pretty much front surfing only.  But hey, what's so bad about that?  The access eddy is on river right.

To get there, turn in Riggins onto the Main Salmon River Road and drive about 17 miles.  You'll see a cable crossing the river to a house: this is the only way for these folks to get home so please don't park in their parking spots.  Instead, park on the hill in the pullout and walk down to the river.
