A car-free island stuck happily in time
Mackinac Island sits in Lake Huron between Michigan's lower and upper peninsulas, and its defining quirk is that motor vehicles have been banned since 1898. Travel here is by bike, on foot, or in a horse-drawn carriage, which makes it one of the most relaxing and kid-safe destinations in the Great Lakes. You reach it by a roughly 20-minute ferry from Mackinaw City or St. Ignace, and a single day is enough to hit the highlights. It is the most memorable stop on our Great Lakes family road trip.
Bike the 8-mile shore loop
The signature activity is pedaling M-185, the only state highway in America where cars are forbidden. The flat 8.2-mile loop hugs the shoreline the entire way, so even young riders can finish it, and you can stop whenever you like for a beach break or a snack. Rental shops cluster near the ferry docks and offer tandems, tag-alongs, and trailers for toddlers. Plan about 1.5 to 2 hours with stops, and ride clockwise to keep the water on your right.
- Distance: 8.2 flat miles around the island
- Rentals: available downtown by the hour or day
- Best stops: Arch Rock, British Landing, and Devils Kitchen sea caves
Hike to Arch Rock and the island interior
Most visitors only circle the shore, but the wooded interior is laced with quiet trails inside Mackinac Island State Park, which covers about 80 percent of the island. The must-see is Arch Rock, a natural limestone arch standing nearly 150 feet above the lake; you can bike to its base on the shore road or hike up through the woods to the top overlook. Other rewarding short walks lead to Sugar Loaf, a towering limestone stack, and Skull Cave, each with interpretive signs that keep kids engaged.
Fort Mackinac and the town
Fort Mackinac crowns the bluff above downtown and is worth the climb up the ramp from Marquette Park. Costumed interpreters fire the cannon and rifles on a schedule, and the fort cafe has one of the best lunch views in the state. Down in the village, Main Street is lined with historic fudge shops, the island's signature treat, where you can watch slabs being folded on marble tables. The Grand Hotel and its famous 660-foot porch are a short walk or carriage ride away.
Practical tips for families
Buy ferry tickets in advance during July and August, and check the last return departure so you do not get stranded. There are no chain stores or gas stations, so bring sunscreen and water with you. If you are staying overnight, your luggage is moved by horse-drawn dray rather than car. The island is open seasonally, with most services running from early May through late October; the fall color in early October over the Mackinac Bridge is stunning.
- Ferry from: Mackinaw City or St. Ignace, about 20 minutes
- Go early: first ferries beat the cruise-ship and day-trip crowds
- Allow a full day: bike the loop, climb to the fort, and save time for fudge
Pair it with the mainland parks
Because the ferry docks are right in Mackinaw City, the island slots perfectly between the Sleeping Bear Dunes to the south and Pictured Rocks to the north across the Upper Peninsula. A common rhythm is dunes and Traverse City first, a Mackinac Island day in the middle, then up into the U.P. for Lake Superior. See how it all connects with kid-friendly drive times in our 7-day Great Lakes itinerary.
