Old Mill Campground sits in Old Mill State Park, offering tent sites, primitive camping, and cabin lodging near Coon Lake and Pine Lake. Reservations are required for campsites. The park runs evening naturalist programs and moonlit walks during summer months.
Park offers tent/backpack sites and camper cabins (camping and backpacking opportunities reported).
Weather and SeasonsSummer brings daytime highs in the mid-70s to mid-80s°F, warm enough for comfortable swimming in Coon Lake and Pine Lake. Evenings cool down but stay pleasant for campfires. Mosquitoes are thick in July and August; reviewers consistently recommend bug spray. Fishing for bass and panfish peaks in summer, and the park schedules most programs during warm months. Expect busier weekends in July and August. Off-season visits dodge the bugs but may catch seasonal closures. Check ahead.
Natural Features and SceneryThe campground sits between Coon Lake and Pine Lake, with some sites perched above the water and accessible by stairs. Eskers. Glacial ridges. Rise near the shore, crossed by boardwalks and hiking trails. The Chase Point area overlooks the lakes from higher ground. Forests around camp support loons, songbirds, and dragonflies. Lake views open up from waterfront sites, though interior loops have less elbow room and thinner tree buffers. Wildflowers line trails in summer.
