Duluth MN Loop. Circle the world's largest freshwater lake through three states and one Canadian province. From the North Shore waterfalls of Minnesota through the wild Ontario wilderness to the copper country of Michigan's Upper Peninsula.
Lake Superior is the largest freshwater lake on Earth by surface area. Circling it means driving 2,100 km through some of the most wild, unpopulated, and genuinely beautiful landscape in North America. This is not a curated tourist route. Much of it is raw wilderness with no cell service, no guardrails, and no crowds.
The circle tour takes you from the craft breweries and shipping port of Duluth, along Minnesota's waterfall-studded North Shore, across the Canadian border into the boreal forest of Ontario, through copper mining ghost towns on Michigan's Keweenaw Peninsula, and past the sea caves of the Apostle Islands before looping back to Duluth.
What makes this route special is the sheer scale and isolation. On the Ontario north shore, you can drive for two hours without seeing another car. The lake itself is so large it creates its own weather systems. You are circling an inland sea that holds 10% of the world's surface fresh water, and it shows in every kilometer.
7 days, 2,100 km, two countries, and enough stops to fill a lifetime of stories.
Watch freighters pass under the lift bridge from Canal Park. The Maritime Visitor Center is free and worth an hour. Best time for ship watching is mid-morning.
A stone observation tower with panoramic views of Duluth, the harbor, and Lake Superior. Short walk from the parking lot. Go at golden hour for the best light.
The oldest operating lighthouse on the North Shore, built in 1892. You can tour the inside and even stay overnight in the keeper's quarters. Book well in advance for summer.
Betty's Pies on Highway 61 is a North Shore institution. Get the five-layer chocolate pie. Arrive before noon to avoid the line.
Perched 40 meters above the lake on a cliff face. The most photographed lighthouse on the Great Lakes. The history center explains the 1905 storm that prompted its construction.
Five waterfalls within easy walking distance. The Upper Falls trail is 0.8 km round trip. Go in the morning when the light hits the falls through the trees.
An artist colony of 1,300 people on a natural harbor. Walk the breakwater to the lighthouse. Browse galleries on Wisconsin Street. The Gunflint Trail starts here for backcountry access.
The Angry Trout serves Lake Superior fish caught that day. World's Best Donuts opens at 7am and sells out by noon. Not an exaggeration on the name.
The last stop before the Canadian border. This was the center of the North American fur trade in the 1700s. The reconstructed depot and Great Hall are fascinating.
You will need a valid passport or enhanced driver's license. The Pigeon River border crossing is small and usually fast, but summer weekends can add 30-45 minutes. Have your documents ready.
Known as the Niagara of the North. A 40-meter waterfall on the Kaministiquia River. The boardwalk viewpoints give you multiple angles. The rock here contains some of the oldest fossils on Earth.
Thunder Bay claims to have invented the Persian, a cinnamon bun with pink icing. The Persian Man bakery is the original. Try a Finnish pancake at the Hoito Restaurant, open since 1918.
A massive mesa formation that looks like a sleeping giant from Thunder Bay. The Top of the Giant Trail is 22 km round trip and one of Ontario's best hikes. Shorter trails available near the campground.
The only river that drains into Lake Superior from the north. Stop at the Nipigon River Recreation Trail for a short boardwalk walk. Brook trout fishing is world-class here.
Claims to be the coldest spot in Ontario (hit -58C in 1935). More importantly, a black bear cub from here inspired Winnie the Pooh. There is a statue of Winnie in town.
Limited dining options. The Robin's Donuts in town is the social hub. Pack snacks and a cooler for this leg of the trip. Groceries are limited between Thunder Bay and Sault Ste. Marie.
Canada's wildest Great Lakes park. The Coastal Hiking Trail is 60 km of backcountry, but the Southern Headland Trail (2.2 km) gives you a taste of the rugged shoreline. Watch for caribou.
Agawa Rock Pictographs are 400-year-old Ojibwe rock paintings accessible via a steep trail to the water's edge. Only safe to visit in calm conditions. Check with the park office first.
Watch the Soo Locks raise and lower freighters between Lake Superior and Lake Huron. The viewing platform is free. A boat tour through the locks is one of the most unique experiences on the Great Lakes.
Cross to the Michigan side for a classic Upper Peninsula pasty. A pasty is a meat-and-potato hand pie brought by Cornish miners. Every restaurant claims theirs is the best.
The second-largest waterfall east of the Mississippi. Root beer colored water from tannins, not pollution. The Upper Falls are 60 meters wide. A boardwalk makes it wheelchair accessible.
The full experience requires a boat tour from Munising (3 hours), but Miners Castle overlook is a 10-minute walk from the parking lot and shows you the signature multicolored cliffs.
The northernmost point in Michigan, jutting 100 km into Lake Superior. Copper Harbor at the tip has a population of 86. The Brockway Mountain Drive is the highest paved road between the Rockies and the Alleghenies.

A 15 km drive to the highest point on the Keweenaw. On clear days you can see the shoreline of the Upper Peninsula stretching in both directions. Sunrise from the top is worth waking up early.
21 islands with sea caves, lighthouses, and pristine beaches. A boat tour from Bayfield WI is the best way to see the sea caves. In winter they freeze into ice caves, but summer kayaking through them is unforgettable.
Population 487 but packed with charm. Victorian architecture, orchards, and the ferry to Madeline Island. The annual Apple Festival in October draws 60,000 people to this tiny town.
Back in Duluth, celebrate the completed loop at Lake Avenue Restaurant for the best Lake Superior whitefish in the city. Fitger's Brewhouse is a great backup in a converted 1885 brewery.

This route crosses an international border and passes through genuine wilderness. Preparation matters.
You will need a valid passport or NEXUS card to cross into Canada at Grand Portage/Pigeon River and again when re-entering the US at Sault Ste. Marie. An enhanced driver's license works for some states. Check requirements well before your trip.
Cell service is extremely limited on the Ontario north shore between Thunder Bay and Sault Ste. Marie. Stretches of 100+ km with zero signal are common. Download offline maps and tell someone your itinerary.
Lake Superior's water temperature rarely exceeds 55F (13C) even in August. Hypothermia can set in within minutes. Never swim alone and always test conditions before wading in.
Moose are active at dawn and dusk along the Trans-Canada Highway in Ontario. A moose collision is often fatal for the driver. Slow down during these hours and watch for eye shine.
Gas stations are sparse on the Canadian north shore. Fill up at every opportunity between Thunder Bay and Sault Ste. Marie. Some stretches have no services for 150+ km.
Weather on Lake Superior can change within an hour. Pack layers even in July. Fog, wind, and cold rain can roll in without warning, especially on exposed headlands.

Answers to the most common questions about driving the Lake Superior circle tour.
Yes. The circle tour crosses into Canada at the Minnesota/Ontario border near Grand Portage and re-enters the US at Sault Ste. Marie. You need a valid passport, passport card, NEXUS card, or enhanced driver's license (available in some states). Standard driver's licenses are not accepted at the border.
Lake Superior's surface temperature rarely exceeds 55F (13C) even in late summer. Some shallow bays and beaches near Marquette or Bayfield can reach 60-65F in August, but open water stays cold year-round. Swimming is possible but brief. Wetsuits are recommended for anything beyond a quick dip. Hypothermia risk is real.
July and August are the best months. Roads are fully open, daylight lasts until 9pm, and all services and attractions are operating. June is beautiful but black flies are at their worst. September offers fall colors but some Canadian services start closing. The route is not recommended in winter due to extreme cold and road conditions on the Ontario north shore.
The full loop is about 2,100 km (1,305 miles) with roughly 22 hours of total driving. Most travelers take 7 days to complete it comfortably with stops. You could rush it in 4-5 days, but you would miss the best parts. The Ontario north shore alone takes a full day of driving with minimal stops.
Yes, but it requires preparation. The biggest risks are moose on the Trans-Canada Highway at dawn and dusk, limited cell service in Ontario, and long distances between gas stations. Keep your tank above half on the Canadian section. The roads are paved and well-maintained, but some stretches are two-lane with no shoulder. Drive defensively and avoid nighttime driving in Ontario.
