The Au Sable River in Michigan runs 140 miles through the northern Lower Peninsula, through the towns of Grayling, Mio and Oscoda. It is a designated trout stream and a portion is a designated National Wild and Scenic River. Many canoe liveries exists along the river and offer canoe trips as much as a week long.

The Au Sable River is also the site of a yearly 120-mile pro-am canoe race, the Au Sable Canoe Marathon, which begins at 9:00 PM and runs through the night into the next day. Winning times have ranged from 14 to 21 hours. The race was first run in 1947.
