Night on the Door County peninsula comes in over Green Bay, the water going dark below the Niagara Escarpment and the campfires starting up along the loops at Peninsula State Park. The park holds eight miles of that shoreline, and its campgrounds run back into the hardwoods between the bluffs and the water. Families tend to keep one site for the whole week and spend the days up and down Highway 42, past cherry orchards and wineries and into the harbor towns along the shore.
Tennison Bay is the campground to aim a rig at. It's the park's biggest, with 188 sites and 97 of them electric (Wisconsin DNR), and South Nicolet Bay and the small Weborg Point campground have electric sites too. North Nicolet Bay and Welcker's Point have no electric at all, and the state park sites stop at electricity, so the rig comes in with fresh water aboard and uses the dump station on Shore Road, east of Tennison Bay.
When Peninsula is full, Egg Harbor, down the shore, has the full-hookup parks. HTR Door County has back-in sites with full hookups, and Rustic Timbers lists electric, water and sewer plus its own dump station, both as of October 2026. Lower on the peninsula, Potawatomi State Park's Daisy Field campground is the fallback for a family that rolls in late, with two loops of 123 sites, 40 of them electric, and a dump station open in season (Wisconsin DNR).
Book the site before the motorhome, since the site you land decides how long a rig makes sense. Both state parks take reservations through Wisconsin's state park booking system, and they're worth booking as early as you can. The DNR publishes no length limit for either park, so call with your rig's length before you commit.
The Wisconsin Dells waterparks and Devil's Lake
The Wisconsin Dells bills itself as the Waterpark Capital of the World, and the family week there is slides all day and a resort campsite with the hookups running when everyone gets back. It's a parked week, with the rig set up on one site from the first night to the last. Wisconsin Dells KOA Holiday has pull-thru and back-in sites, several of them full hookup with a patio and the rest water and electric, as of October 2026. Noah's Ark Waterpark is nearby, and Jellystone Park is the other resort campground families book in town.
Devil's Lake State Park is a short drive south, and its campgrounds, electric loops and reservation rules are on the Devil's Lake State Park RV page. Farther south, Madison's lakes have an RV page of their own, and so does Janesville, down toward the Illinois line.
AirVenture week at Oshkosh
Every July the EAA fly-in at Oshkosh brings 10,000 airplanes onto one field, and Camp Scholler, the show's campground, fills with rigs for the week. AirVenture ties up rigs and pads across the Fox Valley, and it lands in the same summer stretch families are booking Door County and the Dells, so the motorhome you want for July is wanted by both crowds. Lock the campsite first and the rig second. Hookups, generator rules and arrival at Camp Scholler are on the Oshkosh RV page.
Lake resorts around Minocqua and Woodruff
Minocqua sits in the Northwoods chain of lakes, and a rig week there is a parked one at a lake resort, with full hookups and the water out past the trees. Fox Fire Campground, near Minocqua and Woodruff, is mostly full-hookup sites, with a wooded road that runs along the lake. As of October 2026 the park's maximum trailer length is 40 feet, with a waiver beyond that, and 33 feet on the lakeside road. Generators aren't allowed, which full hookups make easy to live with.
For two people, or for a spot on that lakeside road, a smaller rig fits better, and the Wisconsin campervan page covers the Northwoods from its forest campgrounds. That page also has the Lake Superior sea caves of the Apostle Islands, Copper Falls, Wyalusing and Perrot along the Mississippi, and the Kettle Moraine lakes. South and west of the Northwoods, Eau Claire's festival weeks have their own RV page, and Chippewa Falls next door has one too.
