After you get bored of the falls, a few class II-III boogie rapids follow. Keep an eye on the scenery ahead; when you see a sheer cliff face ahead on the right as the river bends left, Grotto Falls is coming up. Following a small slide, beach yourself on the large rock outcropping that divides the flow to scout Grotto. The main line is just a couple feet to the left of the rock you landed on, an easy 8-footer with big boof potential. At low water, keep your boat angled right to miss a piton rock on the left side of this drop. This can also be run further river left as a double drop, just stay away from the undercut bank.
