The Teanaway River that is fed from the majestic Stuart Range.  It's a beautiful class II+ run w/ cool sandstone slides that create some great surf / playspots. 

 

This run has class II / II+ rapids, but it REQUIRES class III skills do avoid a LOT of wood, huge trees, with not the greatest of eddies throughout.  This is not a river for beginners!  You must be confident with boat handling and know you can put your boat where you want it.  There are also mandatory portages that will be made, it will be an adventure, but a beautiful one in the Teanaway River Valley.
