Algonac

Algonac sits at the southern gateway of the Thumb Coast, on the St. Clair River where freighters pass close to shore.

Local character

A working river town with a long boating heritage and a walkable riverfront.

River frontage rather than open Lake Huron beach; swimming is limited and current-dependent.

Deep-water access to Lake St. Clair and the North Channel; multiple marinas and launches.

Algonac State Park, the riverfront boardwalk, and Harsens Island by ferry.

River cottages, canal homes, and small houses with dock access.

Boaters, freighter watchers, and travelers arriving from Metro Detroit.
