Mackinac Island State Harbor
The public marina in Haldimand Bay below Fort Mackinac, steps from downtown Mackinac Island, with mostly transient slips booked through the DNR.
Mackinac Island State Harbor is the island’s public marina, set in Haldimand Bay across from Marquette Park at the foot of Fort Mackinac. Main Street and Market Street, with the island’s shops and restaurants, are a short walk from the docks, and the car-free island is explored on foot, by bike or by carriage.
The harbor is also a working port, shared with ferries and other commercial traffic. Most of its 80 slips are for transient boats, and demand peaks in July around the Chicago and Port Huron races to Mackinac, so boaters are urged to reserve through the DNR well ahead.
Slips, fuel and services
Reservations
Reservations through the Michigan DNR (MiDNRReservations.com) are strongly advised. Slips are hardest to get during the Chicago and Port Huron sailboat races, and the state tourism listing notes limited availability from mid-June to late July.
Transient slips
Most of the harbor's 80 slips are for transient boats by the day or overnight, with a few seasonal slips. The island's tourism bureau lists a maximum boat length of 74 feet.
Services
Electricity, water, restrooms, showers, picnic tables, grills and Wi-Fi are listed. The harbor is across from Marquette Park and a short walk from Main and Market streets.
Anything not listed here is unverified. Contact the harbor before arriving. Not for navigation: use current NOAA charts and the NWS marine forecast.
