[4] Directly north of the state park, the Kohler company has proposed to clear as much as 200 acres of forest, which may affect as much as 80 acres of protected wetlands, in order to construct an 18-hole golf course along the shore of Lake Michigan.

It is accessed north of the park on County Highway V. It passes through open fields, woodlands, and evergreen forests.

[11] Facilities at the park include a bath house, campgrounds, roads, and trails.

[12][needs update] The Sanderling Nature Center is located in the northern area of the park.

The center is open from May through October featuring park displays, an auditorium and an observation deck with a view of Lake Michigan.
