The Ahnapee rises in southern Door County and flows generally southeastwardly into northeastern Kewaunee County, past the village of
Forestville, where it is
dammed. Downstream of Forestville the river becomes a
freshwater estuary of Lake Michigan and is paralleled by a
rail trail called the
Ahnapee State Trail.[2] It joins Lake Michigan at the city of Algoma.[3] The length of the river from Forestville to Algoma has ten public access points.[4]
