One of a few lakes in southwestern Wisconsin, 450-acre Yellowstone Lake is a popular year-round recreation area that offers visitors ample space to enjoy camping, swimming, fishing, boating, hiking, biking and picnicking. In winter the park is open to ice fishing, snowmobiling and cross-country skiing. A large family campground and group camp are just a short walk from the beach and boat landing.
Is Yellowstone Lake 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 Yellowstone Lake State Park in Blanchardville, 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 Yellowstone Lake State Park for cancellations is the paid part.
