William G. Milliken State Park and Harbor is Michigan’s first urban state park, a Detroit River waterfront park at 1900 Atwater St, Detroit, Michigan 48207, United States of America, in the Rivertown/East Riverfront district. Established in 2003 and named for former Michigan governor William G. Milliken, the park combines a working recreational harbor, a landmark lighthouse, riverfront paths, wetland habitat and shoreline fishing. Travelers come for close-up views across the Detroit River toward Windsor, Ontario, and direct access to the Detroit RiverWalk.
What to Expect at William G. Milliken State Park and Harbor
The park’s defining architectural feature is its 63-foot, white conical lighthouse, an automated structure built as a contemporary tribute to Great Lakes navigation lights. It stands beside the harbor basin and makes an easy visual marker from the RiverWalk. The seasonal harbor has 52 slips for recreational boaters, while land-based visitors can use the riverside promenade, fish from the pier and pause at benches and picnic tables facing the international waterway.
This is an active public landscape rather than an indoor museum: its interpretation focuses on the Detroit River, wetland ecology and the working waterfront. Paved paths connect the lighthouse, harbor and restored wetland area to the broader Detroit RiverWalk. Watch for freighters, pleasure boats and waterfowl; bring a Michigan fishing license if you plan to fish. The flat waterfront setting works especially well for a short walk between downtown attractions or as a calmer stop before continuing east or west along the river.

Visiting Tips, Getting There & Nearby Pairings
Arrive in the morning for quieter paths and softer light on the lighthouse, or come near sunset for long views over the river. There is no general-admission ticket to book. Drivers should confirm Recreation Passport requirements before parking, and boaters should contact the park office or Michigan DNR for current harbor-slip availability and seasonal procedures. The DDOT 9 Jefferson route is the most useful bus connection; from Jefferson Avenue, walk south toward Atwater Street and the river. Downtown visitors can also reach the park on foot or by bicycle via the RiverWalk.
The principal riverfront routes are paved and largely level, making them practical for wheelchairs, strollers and walkers who prefer minimal grade changes. Accessible parking and accessible restroom facilities are available at the park; conditions can be affected by weather, construction or riverfront events, so call ahead for specific needs. Pair a visit with the Dequindre Cut Greenway entrance near Orleans Street, the Aretha Franklin Amphitheatre just west along the river, or Valade Park to the east. Atwater Brewery’s Detroit Tap House, near Joseph Campau Avenue, is also an easy walk for food and drinks.
