O'Neil Creek's creek-fed beach on Lake Wissota is where the kids come down off the jumping pillow and the mini-golf course for one last swim. The rig waits back at the site, and it isn't going anywhere until the end of the week. Over at Pine Harbor the same week happens under the trees, and both private campgrounds sit on the Chippewa River impoundment just outside Chippewa Falls.
Days off the water head back into town. The Leinenkugel's brewery tour is the obvious afternoon, and downtown Chippewa Falls handles dinner after it. For a bigger outing, the Chippewa Moraine near New Auburn is glacier country, ridges and hollows the last ice sheet left behind, and you're back at the lake by dark.
O'Neil Creek or Pine Harbor on Lake Wissota
O'Neil Creek is the bigger of the two and the one built around kids, four miles north of Chippewa Falls where Lake Wissota meets the Chippewa River. The same listing counts 87 RV sites with water and electric, and the ones worth booking early are the 19 with 50-amp service, the 25 with sewer, and the 10 pull-throughs.
Pine Harbor is smaller and shadier, with 21 RV sites on water and 20/30/50-amp electric back in the woods by the lake. It has a dump station on site, as O'Neil Creek does, so a week on water and power means one run to the dump partway through and another on the way out.
Lock the campsite before you book the rig, since summer weekends are the crowded stretch on the lake. Give the campground your rig's length when you reserve, and let the site you land decide how big a motorhome or trailer to rent. Lake Wissota State Park on the same water runs its own campground, and the Eau Claire campervan page covers that trip.
Fair Hill Campground, a walk from downtown
Fair Hill takes its name from the ski-slide hill on the Northern Wisconsin State Fair grounds, and a weekend there trades the lake for town. Downtown and the Leinenkugel's brewery are within walking distance of the campground, and so are Irvine Park and its zoo, which makes it an easy base for a weekend with nothing to drive. A couple doing the brewery and the park for two nights could do it in a smaller Wisconsin campervan instead.
The grounds hold 34 full-service sites with electric, sewer and water, plus electric-only and dry sites, open to the public from early May through the end of September on a first-come basis as of October 2026. Event weekends close the campground to the public, among them the swap meet, the dog show, Picks and Pours, and Oktoberfest.
The biggest closure is the Northern Wisconsin State Fair itself in mid-July, when the grandstand fills and public camping on the hill shuts from late June into mid-July. Fair week brings RV demand of its own, so it competes with Lake Wissota for the same rental motorhomes and the same lakeside sites. Book both early and plan to sleep at O'Neil Creek or Pine Harbor that week.
