A fantastic experience that I do every time I'm in the area. There's a long line during the summer, but it moves fast. You don your blue plastic poncho (can everybody say "free souvenir"?), board the specialized boat, and head off to the base of the falls. The boat pounds through the eddies and whirlpools at the base of the falls, and holds against the base of the falls for a few minutes with the engine pounding at full power just to stay in place.
