Wisconsin has 22 wild islands most Americans don’t know exist and they’re extraordinary

There’s a whole archipelago up here

Twenty-two islands sit off the northern tip of Wisconsin’s Bayfield Peninsula, right where Lake Superior gets wide and cold and wild. The National Lakeshore protects 21 of them, plus a 12-mile stretch of mainland shore.

This is Ojibwe homeland, and the connection goes back thousands of years. Only one island has year-round residents.

The rest belong to sandstone, lighthouses, black bears and whoever paddles out far enough to find them. The caves alone are worth the trip, but they’re just the start.

The Ojibwe called Madeline Island home first

Long before French explorers showed up, the Ojibwe built their main village on Madeline Island and called it Moningwunakauning, meaning “Home of the yellow-breasted woodpecker.”

They fished year-round, gathered wild rice each fall, tapped maple trees in late winter and picked berries through the summer.

In the late 1660s, Jesuit priests Claude Allouez and Jacques Marquette set up a mission on the island, making it one of Wisconsin’s oldest European settlements. The French named the chain Les Isles des Apotres.

Fur traders, loggers and quarry workers followed over the next two centuries.

Billion-year-old sandstone carved into cathedral chambers

The rock here started forming about 1.2 billion years ago.

Waves, wind and centuries of freeze-thaw cycles have cut the soft sandstone into tunnels, arches and hollow chambers tall enough to paddle through. Three main cave areas draw visitors.

Devils Island has the most intricate formations. Sand Island stands out for its mottled coloring.

The mainland caves near Meyers Beach run about 2.5 miles along the tallest cliffs. Inside, red sandstone meets blue water while green moss and blue minerals streak the walls.

Eight lighthouses spread across six islands

No other national park site in the country holds more historic lighthouses than the Apostle Islands.

Eight towers stand on six different islands, and six of them earned a group listing on the National Register of Historic Places in 1977.

The lights went up starting in the mid-1800s after the Soo Locks opened in 1855 and connected Lake Superior to the St. Lawrence Seaway.

Raspberry Island Lighthouse, built in 1862, has been fully restored with early 1900s furnishings. Devils Island Light was the last manned station, automated in 1978.

Paddle straight into the caves by kayak

Sea kayaking puts you inside the caves, not just looking at them from a boat.

You glide through narrow openings, pass under natural arches and drift into chambers that glow with reflected light off the water. The mainland caves near Meyers Beach are the easiest to reach.

Devils Island takes a longer paddle but rewards you with the most elaborate formations. Local outfitters run half-day trips, multi-day camping expeditions and even nighttime tours.

Lake Superior can turn rough fast, so guided trips make sense if you’re new to the water.

Fifty miles of trails cross 14 different islands

The Lakeshore Trail at Meyers Beach runs along high sandstone cliffs right above the mainland sea caves, and it’s the most popular hike in the park.

Stockton Island, the largest in the Lakeshore, has about 14.5 miles of trails winding through bogs, dunes, lagoons, pine forests and an old brownstone quarry.

Julian Bay on Stockton has “singing sands,” a beach where the sand squeaks under your feet. Over on Oak Island, you can follow 11.5 miles of trail to a lookout point roughly 200 feet above the lake.

Take the ferry to Madeline Island’s sandy shore

A 25-minute car ferry from Bayfield drops you in the town of La Pointe, where you’ll find local shops, art galleries and the Madeline Island Museum.

Big Bay State Park covers 2,350 acres on the island’s eastern side, with 1.5 miles of sandy beach, a one-mile accessible boardwalk and over seven miles of hiking trails.

Tom’s Burned Down Cafe, rebuilt from driftwood and found objects after a 1992 fire, draws crowds with live music and an open-air setup. The Wilderness Preserve on the north end keeps things quieter.

The ice caves open once a decade if you’re lucky

When winter temperatures drop hard enough and Lake Superior’s ice coverage tops 90 percent, the mainland sea caves turn into something else entirely. Frozen waterfalls hang from the ceilings.

Needle-like icicles fill the chambers. You walk 1.5 to three miles across the frozen lake from Meyers Beach to reach them.

They opened in 2014 and 2015, then stayed closed for over a decade until Feb. 16, 2026, when a single day of access drew visitors before a storm shut everything down again.

Climate change is shrinking the ice season, and the long-term average maximum ice coverage on Lake Superior sits at only about 60 percent.

Dive 25 feet down to a 373-foot shipwreck

More than 100 shipwrecks have happened in these waters, and over two dozen known sites sit within reach of divers.

Many rest in shallow water, between 25 and 50 feet deep, so you don’t need advanced certification to explore them.

The Sevona, a 373-foot bulk freighter that went down in 1905, lies at about 25 feet on the Sand Island Shoals with iron ore still visible in its stern.

Lake Superior’s cold, clear freshwater keeps the wreck structures well preserved. You’ll need a National Park Service diving permit to go down inside park boundaries.

Camp on 18 islands with black bears nearby

You can pitch a tent on 18 of the 21 islands in the Lakeshore. Sites range from rustic backcountry spots to more traditional campgrounds.

Island shuttles run by Apostle Islands Cruises drop you at popular spots like Stockton and Oak. Stockton’s campground sits right along the southern shoreline with views across to Madeline Island.

Private boats, kayaks and water taxis can get you to the more remote sites.

Fair warning: Stockton Island has historically carried one of the highest black bear densities in the region, so store your food right.

Bayfield packs a 900-person tent theater and apple pie

The small harbor town of Bayfield is where every island trip starts.

Big Top Chautauqua, a 900-person canvas tent near town, has hosted live music and original productions for over three decades.

Every October, the Bayfield Apple Festival pulls in more than 50,000 visitors for orchard tours, food vendors, live music and the Grand Parade down Rittenhouse Avenue.

South of nearby Washburn, the Northern Great Lakes Visitor Center covers the area’s natural and cultural history.

Four miles north of Bayfield, Frog Bay Tribal National Park on Red Cliff Band of Lake Superior Chippewa land is the first tribal national park in the country, with 1.7 miles of trail through boreal forest and undeveloped beach.

Narrated boat tours cover 55 miles of archipelago

Apostle Islands Cruises runs narrated sightseeing tours straight out of Bayfield as an authorized National Park Service concessioner.

The Grand Tour loops roughly 55 miles through the heart of the island chain, passing sea caves, lighthouses and sandstone formations over about 2.5 to three hours.

Guided lighthouse tours bring you onto Raspberry Island and Michigan Island, where park staff walk you through the restored towers and grounds.

Sailing charters with licensed captains head out for day trips or multi-day voyages. Glass-bottom boat rides let you see underwater formations and shallow wrecks without getting wet.

Explore the Apostle Islands in Wisconsin

You can reach the Apostle Islands by driving about five hours north from Madison or roughly six hours from Milwaukee or the Twin Cities.

The National Park Service visitor center sits at 415 Washington Ave. in Bayfield, where you can grab maps, permits and current conditions.

The Madeline Island Ferry runs multiple trips daily from Bayfield to La Pointe and carries cars, bikes and pedestrians. Ice cave access, when it happens, costs $5 per person.

Camping permits are available through Recreation. gov.

Lake Superior stays cold all year, so dress in layers and bring waterproof gear for anything on the water.
