Headlands International Dark Sky Park

The Headlands Dark Sky Park in northern Michigan was one of the first places in the United States to receive International Dark-Sky Association certification in 2011. The 600-acre property on the Lake Michigan shore near Mackinaw City is run by Emmet County and admission is free. On a clear moonless night, the Milky Way is visible as a band of distinguishable structure overhead, dark-adapted eyes can resolve the Andromeda Galaxy as a faint smudge, and the Perseids in August produce visible meteors every few minutes from the beach.

The Viewing

Three things determine the quality of a dark sky visit: clear sky, minimal moon, and dark-adapted eyes. The new moon period gives the darkest conditions; the lunar calendar is the primary scheduling factor. Dark adaptation takes 20 to 30 minutes; arrive before complete darkness and avoid all white light during that period. Red-filtered headlamps preserve dark adaptation while allowing navigation and are the required courtesy here.

The Milky Way core is visible in the south from about 10pm through 3am in summer. The Perseid meteor shower peaks annually around August 11 to 13 and the Headlands holds ranger-led events during the Perseids. The beach access at the western end provides an unobstructed water horizon over Lake Michigan and the Straits of Mackinac, which eliminates ground-level light from the western sky.

Summer Milky Way, autumn Orion and Pleiades, and the Geminid shower in December (the most productive shower of the year, up to 120 per hour, also the coldest) are the main seasonal targets.

The Park

600 acres of shoreline, forest, and wetland. Three miles of Lake Michigan frontage. The Beach Barn visitor centre has astronomy exhibits, restrooms, and covered observation space. The park is open year-round; the primary visiting season is May through October.

Mackinac Island and the Straits

Five kilometres from the park, Mackinaw City is the ferry departure for Mackinac Island. The island has no cars; you arrive by ferry (USD 30 to 35 return from Shepler’s or Star Line) and get around by bicycle or horse carriage. The Victorian resort character, Grand Hotel (1887), and the 13-kilometre perimeter bicycle loop are the main activities. Fort Mackinac (open for tours, USD 14 per adult) covers the military history of the Straits with more depth than most small fort museums.

Where to Stay and Eat

No accommodation within the Headlands. Mackinaw City (five minutes) has motels at USD 90 to 150 in summer. Wilderness State Park, 13 kilometres west, has camping from USD 25 per night and is itself in a relatively dark area. Scalawag’s Whitefish & Chips in Mackinaw City is the recommended local seafood option; Lake Michigan whitefish is what to order.
