Perfect Duluth Day

Favorite Duluth Area Swimming Holes

I have a simple question. Seeing as summer is about to draw to a close, what is your favorite Duluth area swimming hole? The deeps, the shallows, the Lester River train bridge, Lester Park, Twin Ponds and the spot beneath the bridge crossing the St. Louis river on the Willard Munger trail all come to mind. Does anyone have any other favorites aside from spots along Lake Superior?
