Au Sable River

An invasive alga known as didymo, or "rock snot," was discovered in Michigan's Au Sable River, raising concerns with environmentalists and the local fishing community.

This charming rustic Airbnb near Grayling not only offers a great view but is owned by the most hospitable host in Michigan.

Located in the Huron National Forest, just off the River Road Scenic Byway, Iargo Springs is where waters once-believed to be sacred flow to the Au Sable River.
