About Seven Lakes State Park
Seven Lakes State Park covers 1,434 acres near Holly in Oakland County, with a modern 70-site campground set along Sand Lake. It's a smaller, moderate-sized campground compared to the sprawling recreation areas nearby, making it a good pick for campers who want a straightforward lake stay without navigating a huge park.
Sites offer electrical service with 30- or 50-amp options, and the campground includes a designated swimming beach and playscape right along Sand Lake. A sanitation station and toilet and shower facilities round out the amenities, with ADA-accessible sites available. A Recreation Passport is required for vehicle entry.
Things to Do
The swim beach and playscape at the campground make this an easy family destination, and Sand Lake itself offers typical lake-day recreation — swimming, fishing, and casual paddling. The park's location near Holly also puts it a short drive from the town's historic downtown and the larger Holly State Recreation Area's mountain biking trails.
Best Time to Visit
Summer is peak season for the swim beach, while the campground's manageable size makes it a solid shoulder-season option too. It typically operates April through November.
Reservation Tips
Seven Lakes sees steady demand from the Detroit and Flint metro areas but is generally easier to book than the larger recreation areas nearby. Reserve through MiDNRReservations.com within the 6-month window for summer weekends.
Getting There
