Muskrat Lake State Forest Campground sits 12 miles southeast of Mio in the Au Sable State Forest, offering 13 rustic sites along the shore of a warm-water lake. All sites are first-come, first-served. The campground has vault toilets, picnic tables, fire rings, and a hand pump for water, though several reviewers report the pump has reliability issues.
Rustic, small lakeside campground suited to tent campers and small trailers; first‑come, first‑served.
Weather and SeasonsSummer is the main season here. Daytime highs run from the mid-60s to mid-80s °F, with long daylight hours that suit paddling and fishing. Early-season bugs are common, so bring repellent. Weekends fill quickly despite the small site count; midweek arrivals or early mornings give you better odds at a lakeside spot. The campground and seasonal access roads aren't plowed in winter.
Natural Features and SceneryThe campground occupies mixed northern hardwoods and conifers at 1,178 feet elevation, with several sites directly on the lake and others set back in the trees. Muskrat Lake itself is shallow with weedy margins near shore, so most fishing happens by boat or kayak rather than from the bank. Recent logging near the campground has reduced forest cover in some areas and increased wind exposure. The lake offers quiet coves for paddling, and warm-water species like bass and panfish are common catches.
