Brimley State Park
Overview: The Warmest Waters on Lake Superior
Perched on the shores of Whitefish Bay at the far eastern end of Lake Superior—approximately 11 miles southwest of Sault Ste. Marie—Brimley State Park occupies a modest but strategically wonderful position: the one place on Lake Superior’s 2,726-mile shoreline where the water actually gets warm enough for comfortable swimming. The bay’s shallow, protected geography creates summer water temperatures that can reach the mid-60s to low-70s°F—practically tropical by Superior standards—making Brimley the unexpected answer to “Can you swim in Lake Superior?”
Established in 1923 when the Village of Brimley donated 38 acres to the state, the park has grown modestly over the decades but retained its essential character: a sandy beach on Superior, a modern campground in the pines, and the constant maritime spectacle of Great Lakes freighters passing through Whitefish Bay on their way to and from the Soo Locks.
2,000 Feet of Sandy Beach
The park’s 2,000-foot sandy beach fronts Whitefish Bay—a broad, shallow stretch of Lake Superior’s southeastern corner where the water warms substantially more than the main lake body. The sandy bottom, gentle slope, and comparatively warm temperatures create swimming conditions that families can actually enjoy, rather than merely endure.
- Water Temperature: Whitefish Bay can reach mid-60s to low-70s°F in summer—10–15 degrees warmer than the open lake
- Observation Platform: An accessible platform provides elevated views of the beach and passing freighters
- Pet Policy: Pets are not permitted on the beach
Freighter Watching
Whitefish Bay is the primary shipping channel connecting Lake Superior to the lower Great Lakes via the St. Marys River and Soo Locks. From Brimley’s beach, visitors can watch thousand-foot freighters—some of the largest vessels on the Great Lakes—gliding past in stately procession. The combination of sandy beach recreation and industrial maritime spectacle is unique to this stretch of shoreline.
200+ Modern Campsites
The campground offers over 200 modern sites with electric hookups, modern restrooms, showers, and mini-cabin rentals. The campground sits in a pine forest setting just behind the beach, providing shade, privacy, and the fragrance of sun-warmed pine needles.
