About this swimming hole

The M-28 bridge over the Au Train River is a beloved UP ritual: leap from the bridge into the river, then float downstream to the sand beach where the river meets Lake Superior. The jump-float-beach loop makes for a full mini-adventure without leaving the roadside. Depth under the bridge changes with the season, so swimmers always check before leaping.
