Detroit River

The Detroit River is big-water paddling on an international boundary — a 28-mile strait connecting Lake St. Clair to Lake Erie, with downtown Detroit on one shore and Windsor, Ontario on the other. This is not a beginner float: the current runs 3–4 knots south of Belle Isle, and the open river brings commercial freighter traffic, large wakes, reflective waves off seawalls, serious wind exposure, and border-security considerations.

That said, it is one of the most memorable urban paddles in the Midwest. Belle Isle is the classic U.S. put-in, and a roughly 10-kilometer route loops through the Fleming Channel with skyline views, the Ambassador Bridge, and passing lake freighters. For a calmer first taste, a 3-mile guided-style route through the Jefferson Chalmers canals offers sheltered paddling, including some upstream stretches, without the open-water exposure.

Treat this river with expedition-level respect: paddle with experienced partners, stay out of the shipping channels, carry a phone in a dry case or a marine radio, always wear your PFD, and check wind and weather obsessively. This guide covers day-trip sections only — not a through-paddle of the whole strait.

Paddling Sections

Belle Isle loop via Fleming Channel (about 10 km): Launch at Belle Isle and paddle the Fleming Channel around the island’s south side, where the current runs 3–4 knots, then return via calmer water past Reaume Park and Goose Bay Park. Keep well clear of the main shipping channel and give freighters enormous berth.

Belle Isle to Grosse Ile (about 21 miles one way): A documented long-haul route down the U.S. side to a Grosse Ile boat launch. This is an expert-level undertaking — shuttle required, and the lower river’s industrial shoreline offers few bailouts.

Jefferson Chalmers canals (about 3 miles): A sheltered, beginner-friendlier paddle through residential canals off the river, including some upstream paddling. A good first taste of the Detroit River system.

Hazards & Portages

• Commercial traffic and wakes: Freighters cannot stop or turn quickly. Never cross the shipping channel in front of one, and expect large wakes plus reflective waves off seawalls.
• Current and wind: A 3–4 knot current south of Belle Isle combined with open-water wind can exhaust paddlers fast — plan a conservative route.
• International border: The middle of the river is the U.S.–Canada boundary. Carry ID and know the rules for cross-border paddling before you go.
• Cold water: Even in summer the river can be dangerously cold — dress for immersion, not the air temperature.

Access & Parking

Belle Isle: The most common U.S. access, with multiple launch spots around the island. State park entry rules apply (Recreation Passport).

Belanger Park Boat Launch: Downriver U.S. access for the lower river and longer routes.

Jefferson Chalmers: Street-side access for the canal route — scout parking in advance.
