Muskallonge Lake State Park

Muskallonge Lake State Park occupies a narrow strip of land between two very different waters — warm, fishable Muskallonge Lake on one side and the cold, wild expanse of Lake Superior on the other — on the remote Lake Superior shore of Luce County, between Newberry and Grand Marais. This unusual setting gives visitors the best of both worlds in one quiet, scenic park.

Muskallonge Lake offers warm-water swimming, fishing and paddling, while the Lake Superior shore just across the park is famous for agate hunting, beachcombing and dramatic big-lake scenery. Once the site of the vanished logging town of Deer Park, the area is now wild and peaceful, ringed by forest and close to the legendary Two-Hearted River. With its two shorelines, agate beaches and remote, tranquil setting, Muskallonge Lake is a hidden gem of the eastern U.P.

The park’s two-shoreline setting offers warm-water swimming, fishing and paddling on Muskallonge Lake and agate hunting, beachcombing and big-lake scenery on the Lake Superior shore just across the park. A campground, trails and picnic areas serve visitors, and the nearby Two-Hearted River and Lake Superior shore add paddling and exploration. Quiet and remote, it rewards those seeking a peaceful base for swimming, fishing, rock hunting and exploring the wild eastern U.P. coast.

Summer brings warm Muskallonge Lake water for swimming, full use of the campground, and the best conditions for the beaches — reserve campsites early. Spring and fall are prime for agate hunting on the Lake Superior shore after storms churn the beach, with fall color through the forest. Winter is remote and snowy. Summer and fall are best, combining the warm lake, the wild Superior shore and the agate hunting in the quiet eastern U.P.

The park sits where the logging town of Deer Park once bustled in the 19th century, a busy lumber port on Lake Superior that vanished when the timber was gone, leaving the area to return to wild forest. Muskallonge Lake State Park was later developed on the narrow strip between the two lakes, preserving public access to both shorelines and the agate beaches, and the quiet, remote setting recalls the area’s vanished logging past.

Muskallonge Lake’s Lake Superior beaches are famous for agates and water-worn stones, eroded from the ancient bedrock of the Superior basin and tumbled smooth by the waves. The narrow strip of land separating warm Muskallonge Lake from cold Lake Superior, the sandy and cobble shores, and the surrounding forest were shaped by the lake’s waves and the Ice Age glaciers. The contrast of the two waters and the agate-rich Superior beach define the park’s geology.

The two lakes, their shores and the surrounding forest host white-tailed deer, black bear, beaver and a variety of birds, with loons and waterfowl on Muskallonge Lake, gulls and migrating birds along the Lake Superior shore, and bald eagles overhead. The Lake Superior coast is a migratory route, and the quiet, wild setting makes for excellent birding and wildlife watching at this remote eastern-U.P. park.

The park protects a distinctive setting where warm Muskallonge Lake and cold Lake Superior meet across a narrow strip of forested land, each supporting different aquatic life. The Lake Superior shore, dunes and beach are fragile, agate-rich habitat, while Muskallonge Lake’s warmer water supports a different fishery. The surrounding forest and the nearby Two-Hearted River add to a rich, quiet eastern-U.P. ecosystem preserved within the park.

Muskallonge Lake State Park, with its two shorelines, agate beaches and quiet, remote setting on the site of the vanished logging town of Deer Park, is a beloved hidden gem of the eastern Upper Peninsula. Close to the legendary Two-Hearted River of Hemingway fame, it anchors the wild, peaceful character of this stretch of the Lake Superior shore, cherished by anglers, rock hounds and those seeking solitude.

Muskallonge Lake State Park is on County Road 407 on the remote Lake Superior shore in Luce County, between Newberry to the south and Grand Marais to the west — reached by paved and gravel roads through the forest. A Michigan Recreation Passport is required. The campground, beaches on both lakes, trails and picnic areas are within the park. The area is remote, so come prepared; the town of Newberry provides the nearest services. Check the DNR for current access.

The DNR manages Muskallonge Lake to protect its two shorelines, the agate-rich Lake Superior beach, the dunes and the surrounding forest while supporting recreation. Visitors help by staying on trails and beaches to protect the dunes and shoreline, hunting agates responsibly within state limits, keeping the beaches clean, and respecting the remote, quiet setting. Protecting the shorelines and forest preserves both the scenery and the agate-hunting tradition.

Lake Superior is frigid and can build dangerous waves and currents — swim only in warm Muskallonge Lake, not the cold open lake, and supervise children on both shores. Watch footing on the cobble Superior beach. The park is remote, so come prepared with supplies, as services are far. Bring layers for the cool Lake Superior air, insect protection for the forest, and take care exploring the wild, quiet shore.

A Recreation Passport is required. Follow Michigan DNR fishing regulations on Muskallonge Lake. Agate and stone hunting on the Lake Superior beach is popular — follow state collecting limits and posted guidance. Stay on trails and beaches to protect the dunes and shore. Pets must be leashed. Camp only in reserved, designated sites. Check the DNR for current access and conditions before visiting this remote park.

The legendary Two-Hearted River, made famous by Hemingway, lies nearby, with the remote Lake Superior shore, the town of Newberry, Tahquamenon Falls State Park, and Grand Marais and the eastern Pictured Rocks all within reach. The wild forests, rivers and Lake Superior coast of the eastern U.P. surround the park, making it a quiet base for exploring some of Michigan’s most remote and scenic country.

Enjoy warm Muskallonge Lake for swimming and fishing, then walk across to the Lake Superior shore to hunt agates — best after a storm churns the beach — within collecting limits. Reserve campsites early, come prepared for the remote setting, and bring layers for the cool Superior air. Swim only in the warm lake, not the cold open Superior, and pair a visit with the nearby Two-Hearted River and Tahquamenon Falls.
