High Cliff State Park
October 2026
About
Situated above and below the limestone cliffs of the Niagara Escarpment, this park is the only state-owned recreation area on Lake Winnebago, Wisconsin's largest inland lake. The park offers a marina, campgrounds, picnic areas, observation tower, and important geological and cultural features including effigy mounds, a quarry, and lime kiln ruins.
Family and group campsites, picnic shelters, a large gathering space, and an accessible cabin for people with disabilities are all reservable.
Is High Cliff State Park fully booked?
A campground showing no availability is almost never full for good. People cancel — plans change, weather turns, someone books three weekends and keeps one — and the site goes straight back into the booking system, usually without warning and often at odd hours. The reason sold-out campgrounds feel impossible is not that sites never free up; it is that nobody is watching at the moment they do.
CampHawk watches High Cliff State Park in Sherwood, WI for you. We recheck it every 15 seconds, around the clock, and the moment a site opens we send a text, an email and a push notification, with a link straight to the booking page.
Searching is free and needs no account — the calendar above is live right now. Watching High Cliff State Park for cancellations is the paid part.
