About this swimming hole
The 23-mile National Scenic River stretch of the Au Sable, from Mio to Alcona Pond, is one of the Midwest's classic lazy-river floats. Tubers and paddlers drift a clear, sandy-bottomed river through the Huron-Manistee National Forests. Multiple campgrounds and day-use areas offer river access, beaches, and put-in points.
