Harrington Beach State Park is a 715-acre state park with over one mile of Lake Michigan shoreline near Belgium, Ozaukee County, Wisconsin, managed by Wisconsin DNR. The park features a family campground with electric and non-electric sites, walk-in tent sites, a group campsite, and an accessible cabin, a sandy Lake Michigan beach with seasonal lifeguards, a scenic limestone quarry lake — a flooded remnant of the area’s quarrying history, hiking trails through white cedar swamp, hardwood forest, and along the lakeshore bluff, the Jim and Gwen Plunkett Observatory with regular public astronomy programs, fishing from the breakwater and shoreline, picnic areas and shelters, and a nature center with interpretive programming.
Harrington Beach combines two dramatically different landscapes — the open Lake Michigan shoreline with sandy beach and limestone bluffs, and the interior white cedar swamp that feels like a portal to northern Wisconsin despite being only 30 miles north of Milwaukee.
The flooded quarry lake is a beautiful turquoise-green and a popular photography subject. The Plunkett Observatory hosts regular public stargazing events — unusual for a state park.
