This is the rapid at the third bridge. There are many eddies upstream to catch before running this rapid. At lower levels there are two popular strategies for Troll Hole. The one that I like is to enter left of center angling right and go over the main drop clipping the right side of the hole or boofing into the eddy. The other line is to start right and after you clear the center rocks, paddle hard for the center. At that point you can turn sharply right to clip the hole or boof into the eddy or square up and punch the hole. . At higher levels, dig in and go through the hole or a nice tongue appears in place of the hole. Be careful of the bridge pilings at higher levels.
