Hiking in Door County

• Difficulty Easy (Sentinel) to more difficult (Eagle)
• Miles ~20 mi of marked hiking trails
• Terrain Forest dirt, rocky bluff sections, some gravel
• Access Wisconsin state park admission required (day or annual sticker).

If you only pick one hiking day in Door County, make it Peninsula. The park sits on its own peninsula between Fish Creek and Ephraim: roughly 20 miles of marked hiking trail, eight miles of Green Bay shoreline, and the overlooks everyone photographs. From Fish Creek village you can be on trail in minutes.

Eagle Trail is the one people remember: a two-mile loop the DNR rates more difficult, rocky footing under 150-foot limestone cliffs, then a level stretch along Eagle Harbor. Pair it with Eagle Tower (wheelchair-accessible via a long ramp) when you want the wide bay view without the scramble.

Sentinel from Eagle Tower is the family loop: about two miles of packed dirt through maple, beech, and red pine, with about 0.6 mile graveled for universal access. Fall mushrooms along Sentinel if the kids will slow down. If Eagle’s lot is slammed, Skyline / Sven’s Bluff and Hemlock are the overflow.

Across Highway 42 from the park gate, Fish Creek Park is the village warm-up: roughly 150 acres after the Town of Gibraltar’s 2024 Redmann purchase, with a new crushed-gravel hike/bike path from the boat lot behind the library up the bluff behind the Settlement Shops. No state sticker. A Spring Road boardwalk has been studied; it is not an open trail yet.

• Difficulty Easy to moderate
• Miles 30+ mi of hiking trails (stack or shorten loops)
• Terrain Hardpack dirt, roots, shoreline rock and sand
• Access Wisconsin state park admission required.

Across the peninsula on the northeast tip, Newport is quieter and more remote than Peninsula’s Fish Creek gateway. Wisconsin’s only designated state wilderness park, it has over 30 miles of trail through boreal forest, meadows, and about 11 miles of Lake Michigan shoreline.

Our favorite day is the Europe Bay loop: 7 miles on old logging-road ridges, then the isthmus between Lake Michigan and Europe Lake near the north end. Pack a picnic. The park rewards a slow lunch as much as the miles.

That is not the same hike as the Fern / Europe Bay accessible loop (1.2 miles, wide and flat, interpretive signs). Use the short loop when you want an easy start with kids or mobility limits. Do not treat it as a shortened 7-miler. From Baileys Harbor, Newport is the natural hiking day.

• Difficulty Easy to moderate
• Miles 14.5 mi at Whitefish + ~0.5 mi Cave Point connector
• Terrain Sand, boardwalk, forest dirt, limestone shoreline
• Access Whitefish Dunes needs a Wisconsin state park sticker. Cave Point County Park does not.

On the lake side between Jacksonport and Sturgeon Bay, Whitefish Dunes is a different Door County hike: sand, forest, and shoreline instead of bay cliffs. The DNR lists 14.5 miles of trail through dune and woods, with Old Baldy (about 93 feet above the lake, the tallest dune in the park) as the headline overlook.

Treat Cave Point County Park as part of the same day. The county park’s half-mile forest trail links into Whitefish Dunes on three sides, and the limestone ledges where waves hit the rock are the photo stop everyone knows. Rocks are slick when wet or iced; stay back from edges.

Brachiopod Trail is the 1.5-mile interpretive loop near the picnic area and shore: fossils, dunes ecology, and a Leopold bench. The DNR intends it to be accessible, but weather and terrain can make some sections harder; people using mobility aids may need assistance. Red Trail is the main Old Baldy approach (1.2 miles out and back). Yellow Trail is the longest named loop at 3.7 miles. Black Trail covers more ground toward Cave Point. Stay on marked paths and stairs: dune plants and rare shoreline habitat recover slowly if you cut corners.

• Difficulty Easy (boardwalks) to easy-moderate (ridge paths)
• Miles Several miles of marked sanctuary trails + boardwalks
• Terrain Boardwalk, packed path through ridges and swales
• Access Private sanctuary day pass or membership (confirm current fees at the Nature Center). Kids hike free per current Ridges policy.

The Ridges is one of our favorite places on the lake side, especially with kids. Wisconsin’s first land trust protects about 1,600 acres of ridge-and-swale landscape built by Lake Michigan’s changing shoreline: boreal forest, wetlands, orchids, and boardwalks that let you walk where the ground would otherwise be too fragile.

Start at the Cook-Albert Fuller Nature Center on Hwy 57. The first stretch on Hidden Brook Boardwalk is wide and accessible, then connects toward the Baileys Harbor Range Lights. If that is all you cover, you will not be disappointed. With more time, take the offshoot paths deeper into the ridges.

Across Hwy 57, the Family Discovery Trail is built for kids: interactive stations, forts, dirt play, the hour that is not a quiet boardwalk. Open seasonally (typically May through October); confirm hours. This is a private nonprofit sanctuary, not a state park. Day passes support trail care and research; kids hike free per current Ridges policy. Stay on boardwalks and marked trail. Late spring into early summer is when visitors hope for lady’s slippers.

• Difficulty Easy (rocky and wet near the shore)
• Miles ~2 mi out-and-back
• Terrain Forest dirt, roots; rocky/wet cobble near Moonlight Bay
• Access Free public hiking. No state park sticker. Strict leave-no-trace rules; dogs not allowed.

Just past The Ridges on Ridges Road, Toft Point is the quiet walk when you want solitude without driving to Newport. The main trail runs roughly a mile through maple, hemlock, and boreal woods to the rocky dolomite shoreline on Moonlight Bay, about two miles round trip.

This is a State Natural Area managed by UW-Green Bay (about 743 acres; the DNR SNA listing is 732): National Natural Landmark, Ramsar wetland recognition, orchids, warblers, and a shoreline that feels farther from town than it is. Along the way you pass remnants of the old Toft resort cottages and one of Wisconsin’s best-preserved early circular lime kilns.

Treat it gently. Parking is tiny; if the lot is full, come back later or carpool from Baileys Harbor Ridges County Park or Town Hall. No dogs, no bikes, no camping or picnicking, and stay on the trail. The shore end gets rocky and wet; wear real shoes.

• Difficulty Easy
• Miles ~3 mi of public campus trails
• Terrain Dirt path, shoreline, woods and meadow
• Access Private campus trails open for respectful public walking. Confirm any posted rules before you go.

Unless you are staying at the Björklunden retreat center (Lawrence University), you might not hear about these trails. That is part of the appeal: secluded shoreline and mixed woods when Peninsula feels busy.

Lawrence describes about three miles of publicly accessible trail on the 441-acre north campus, including Lake Trail, Quarry Trail, and Turbine Pass. The shoreline stretch along Lake Michigan is the highlight; stack the inland loops if you want a longer easy walk.

Main campus address is 7590 Boynton Lane, just south of Baileys Harbor. Public walking on marked trails is welcomed; this is still a private campus and retreat landscape, not a state park. Stay on marked trail, keep groups small, and follow any posted access notes.

• Difficulty Easy
• Miles ~1.2 mi main trail
• Terrain Cliff-top path, stairs to observation deck
• Access Door County park; no state park sticker required.

We love Ellison Bluff less for a big trail system (there is essentially one main walk) and more for the setting. The park sits on the Niagara Escarpment: a path along the top of 100-plus-foot cliffs with westerly views over Green Bay.

A short stairway leads to an observation deck. The full loop is about 1.2 miles, which makes it perfect with kids, for birding, or as a sunset stop before dinner farther north (Wickman House in Ellison Bay is our usual pairing).

No state park sticker here; it is a Door County park. Bring a light layer. The bluff can feel windier than the woods even on warm days.

• Difficulty Easy to moderate
• Miles ~6 mi of hiking trails (stack or shorten loops)
• Terrain Forest dirt, bluff, Green Bay shoreline
• Access Wisconsin state park admission required (day or annual sticker).

Southwest of Sturgeon Bay, Potawatomi is southern Door’s trail park: 1,178 acres of woods and Green Bay shoreline, about six miles of hiking, and usually fewer people than Peninsula on a July Saturday.

This is the eastern terminus of the Ice Age National Scenic Trail. The marker sits near the old ski hill overlook. Walk the park’s 2.8-mile Ice Age segment, or just stand at the start of a thousand miles. Either way, it is the fact that makes this more than “the other state park.”

Tower Trail is the 3.6-mile loop to the old observation tower site on the highest bluff in the park. Hemlock (2.6 miles) starts at Picnic Lot 2 and works the shoreline and campground woods. Ancient Shores is the 0.5-mile interpretive loop from the Nature Center: three ancient lake levels, easy with kids. State sticker at the gate.
