The run is class 2 moves, but approaches class 3 or higher for its continuity.
There are a few spots to note, about 2-3 miles from the end there is some concrete in the middle of the river, like a piece of road washed down, so that should be avoided on the right. It is visible from the road along the drive up There are a few slides, one set about a mile from the end and the other entering into the casselman. Take out at Harnedsville bridge or somewhere along the Middle Yough.
