The overnight a Michigan RV week is built around comes on the bluff at Straits State Park in St. Ignace, with the Mackinac Bridge's towers and cables strung across the Straits toward Mackinaw City. On the south shore, the Bridgeview pads at Mackinaw Mill Creek Camping look back at the same span, so whichever side you sleep on, the bridge is out the windshield at breakfast. Every rig bound for the Upper Peninsula crosses it, which makes the Straits the hinge of the whole trip.
With a second night booked, the island day is easy. Leave the motorhome plugged in on its pad, ride a passenger ferry across to Mackinac Island, and spend the day by bike and on foot on an island that keeps cars off its streets. The rig is waiting with the power on when the evening boat brings you back.
The crossing itself is slow by design. The Mackinac Bridge Authority holds traffic to 45 mph, with no stopping and no U-turns on the bridge, and it can restrict traffic further for weather or construction, as of October 2026. From the west side of the state, the road here runs through the up-north week the Grand Rapids RV page lays out, with Ludington State Park and Petoskey on the way up and US-131 home.
Straits State Park and Mackinaw Mill Creek, a base under the bridge
On the St. Ignace side, Straits State Park runs from sites on the water up to a loop on the bluff, and the upper loop is the one for a motorhome. It has 20/30-amp electric, some 50-amp sites and some pull-throughs, while the lower loops are smaller and suited to small trailers. The waterfront sites put you right on the Straits but run without electric, and the DNR doesn't allow generators or power cords there, so a waterfront night is a dry one.
Across the bridge in Mackinaw City, Mackinaw Mill Creek Camping is the full-hookup base, a big private campground that opens for the season in May. Its extra-large sites carry 50-amp full hookups and mostly measure at least 30 feet wide by 50 deep, some 40 by 70, with pull-throughs available, against roughly 25 by 50 for a standard full-hookup site.
Book the pad before the rig. A dry waterfront night at Straits, an electric site on the bluff and an extra-large pull-through at Mill Creek are three different trips, and the pad you land decides how much motorhome is worth renting. Straits sites reserve through midnrreservations.com or 800-447-2757.
Tahquamenon Falls and the Upper Peninsula week
North of the bridge, the road runs up into the Upper Peninsula's woods toward Tahquamenon Falls, the second base of the week. The Upper Falls pours amber, tannin-stained water over a drop more than 200 feet wide, with foam piling up on the river below it.
Rigs sleep at the state park's two modern campgrounds, Lower Falls and Rivermouth, usually for two nights. Lower Falls has 30-amp service at every site, with some 50-amp and pull-throughs, and Rivermouth runs electric with some 50-amp sites and pull-throughs of its own. Both book through the same DNR system as Straits, so lock them in before the rig too.
Each campground has its own sanitation station, and that sets the rhythm of the loop. Run the dry waterfront night at Straits, empty the tanks at the park's sanitation station on the way out, plug in at the falls, then dump again before heading west to Munising on Lake Superior for two or three nights near Pictured Rocks. Pictured Rocks from the tour boats, Tawas Point on Lake Huron and the Straits as a one-night stop are written up for two people in a smaller rig on the Michigan campervan page.
Interlochen, the Lake Michigan shore and Michigan's race weekends
Closer to home, the Traverse City RV page sleeps at Interlochen State Park between Duck and Green lakes and sends the day out to the dunes at Sleeping Bear. On the southwest shore, Holland State Park's campground on Lake Macatawa anchors the Holland RV page.
Inland, the Kalamazoo RV page keeps rigs in town at Markin Glen County Park, close to the Kal-Haven Trail. Michigan State home weekends lead the Lansing RV page, with Sleepy Hollow State Park on Lake Ovid as the quiet pad.
Michigan's loudest weekends compete with all of these for the same rigs and the same pads. NASCAR at Michigan International Speedway packs the Irish Hills around Brooklyn, and Electric Forest turns the woods at Rothbury into a festival city, so an up-north week that overlaps either one is chasing the same motorhomes as the crowd.
