The city of Ferrysburg is south of the township bordering Lake Michigan, the Grand River and Spring Lake. On the south side of the Grand River is the city of Grand Haven and Grand Haven Charter Township. Crockery Township is to the east and Muskegon County is to the north. It was established in 1855.
Spring Lake separates the township into two sections: one to the north of Ferrysburg and west of Spring Lake and the other to the east of Spring Lake and north of the Grand River (and area including the village of Spring Lake). There is only one bridge across the lake, M-104, which connects the village of Spring Lake with Ferrysburg. The only other way around the lake requires going north into Muskegon County. There is also a small peninsula in the Grand River, which is part of the Grand Haven State Game Area, where the only road access involves going through Crockery Township.
