Along the Au Sable River is the Au Sable Special Area, a 10,628 acre area characterized by flat to gently rolling hills with some steep banks along the Au Sable River. This area is located in Iosco and Alcona counties. The Au Sable Special Area stretches the southern end of Alcona Dam Pond (Bamfield Road) to just before Cook Pond on either side of the river. The area is densely forested and inhabited by bald eagles, deer, bear, bobcat, porcupine and various songbirds. Campers and day-use visitors enjoy boating, tubing, rafting, canoeing and fishing on the Au Sable River. Other popular recreation activities include viewing the river and wildlife, hiking, swimming, picnicking, horseback riding, hunting, trapping and berry and mushroom gathering. The Forest Service requires camping permits from May 15 through September 30 at the 19 designated primitive campsites along the river in this area. Two developed campgrounds are located in this area, South Branch Trail Camp and Rollways Campground .
