Wisconsin’s most overlooked state park has ice age cliffs, a tower, and zero crowds

Potawatomi’s got more than you’d expect

Door County pulls most visitors straight up the peninsula to Peninsula State Park. That’s fair.

But about 10 minutes northwest of Sturgeon Bay, a 1,225-acre park sits quietly on the shore of Sawyer Harbor, and it runs the same dramatic Niagara Escarpment scenery with a fraction of the foot traffic.

Potawatomi State Park has limestone cliffs, a rebuilt observation tower, the end of a 1,200-mile hiking trail, and enough to fill a long weekend. The crowds haven’t caught on yet.

From limestone quarry to Wisconsin’s public land

The Bo-De-Wad-Me people, meaning “keeper of the fire,” lived along these shores long before anyone drew a state line.

The federal government started quarrying the limestone here in 1834, cutting stone used to build harbors across Lake Michigan.

Over the following decades, the land got considered for a military fort, a naval training center, and a national park before Wisconsin finally bought more than 1,000 acres from the federal government.

The state legislature created the park in 1928, and it opened to the public in the summer of 1930.

The 1931 tower that nearly didn’t survive

A local civic group called the Sawyer Commercial Club paid to build the park’s 75-foot wooden observation tower in 1931, making it the first purpose-built recreational observation tower in any Wisconsin state park.

It stood for 86 years before engineers found serious wood decay and closed it in December 2017. It took years of community pressure and about $1 million in state restoration funding to bring it back.

The tower reopened in spring 2025, rebuilt to preserve its historic look while making it safe again.

Two hundred and twenty-five feet above Sturgeon Bay

The tower sits on the park’s highest bluff along the Niagara Escarpment, and the viewing platform puts you about 225 feet above the bay.

On a clear day, the view stretches miles across Green Bay, with Sawyer Harbor directly below and the open waters of Sturgeon Bay beyond that.

A fully accessible overlook has been proposed as part of a state capital budget project, so visitors who can’t climb the stairs may eventually get the same view from the ground.

Where a 1,200-mile trail comes to an end

Potawatomi holds the eastern terminus of the Ice Age National Scenic Trail, one of only 11 National Scenic Trails in the country and now a unit of the National Park System as of 2023.

The trail runs 1,200 miles entirely within Wisconsin, tracing the edge of the last glacier to cover the state. A 2.8-mile segment winds through the park along the Niagara Escarpment with views of Sturgeon Bay.

The terminus marker, a large glacial boulder, sits at the Old Ski Hill Overlook. For long-distance hikers, that rock is the finish line.

Four trails ranging from a stroll to a solid half-day

The Ancient Shores Nature Trail gives you a quick 0.5-mile loop near the nature center, with signs explaining three ancient shorelines and what lives here.

The Hemlock Trail stretches 2.6 miles at an easy-to-moderate pace along the shoreline and through the woods. The Tower Trail loops 3.6 miles through forest and along the shore before climbing to the observation tower.

Stack the Ice Age Trail segment onto the Tower Trail and you’ve got about six miles of moderate hiking. Pick up a free paper map at the park office because the junctions can get confusing.

Paddle the rocky dolomite shore by kayak

About 2.5 miles of shoreline run along Sawyer Harbor and Sturgeon Bay, and you can rent a kayak, canoe, or paddleboard inside the park.

The limestone shoreline is dolomite, which makes for dramatic scenery from the water. That same rock means no swimming beach, so the appeal here is paddling, not wading.

A boat launch on Sawyer Harbor handles motorboats and sailboats as well. The harbor water tends to stay calm, which makes it a good stretch for anyone newer to paddling.

Some of Wisconsin’s best bass fishing is right here

Sturgeon Bay ranks among the top bass fishing spots in the state.

Beyond bass, you’re likely to pull walleye, northern pike, whitefish, or perch from the water depending on the season.

An accessible fishing pier runs along the southern shoreline, and a fish cleaning station sits near the boat launch. When winter locks up Sawyer Harbor, the ice fishing picks up.

Bring your gear or plan to rent locally, since the park doesn’t stock equipment.

Camp under the trees at Daisy Field

The Daisy Field Campground has 123 sites spread across two loops, with 40 electric hookups and four group sites that each hold up to 30 people.

Trees shade most of the campground through the summer months. Showers and a dump station run during the warm season.

The park also has an accessible cabin built with input from people with disabilities. If you’re planning a summer weekend, reservations fill early, so book as far ahead as the system allows.

Rare beech trees and 200 bird species in the canopy

Sugar maple, basswood, white pine, white birch, and white cedar cover most of the park. Then there are the beech trees.

Beech is rare in Wisconsin, found only within a few miles of Lake Michigan, and Potawatomi has them in numbers.

The bluffs are part of the Niagara Escarpment, the same limestone formation that runs all the way to Niagara Falls.

More than 200 bird species have passed through or taken up residence here, with at least 50 nesting in or near the park.

White-tailed deer, fox, and raccoon move through regularly, and wildflowers cover the ground from spring into fall.

Eight miles of ski trails when the snow arrives

The park grooms about 8.5 miles of cross-country ski trails across four one-way loops in winter, with difficulty levels spread across the system.

Three trails totaling about 2.5 miles stay open for snowshoers and winter hikers. Eight miles of snowmobile trails connect to the Door County system.

A small sledding hill near the campground shelter draws families with kids.

The park ran a downhill ski operation from 1941 until 1998, and the old ski hill overlook is now one of the better viewpoints in the park year-round.

Bikes, picnics and nature programs round out the season

From Memorial Day through Labor Day, the park’s nature center and amphitheater run naturalist programs covering the local ecology.

The Ancient Shores Nature Trail near the nature center works as a quick self-guided lesson in what makes this landscape tick.

Eight miles of off-road bike trails wind through the park, climbing gradually to about 120 feet above Sturgeon Bay.

Picnic areas with tables and grills line the shoreline, and shelter rentals are available for groups. The park stays open year-round, 6 a.m. to 11 p.m.
