Union Bay Campground

About

Union Bay Campground serves as the modern camping hub within Michigan's largest state park, the 60,000-acre Porcupine Mountains Wilderness. The campground offers 100 sites arranged in three rows, all equipped with 20/30-amp electrical hookups, fire rings, and picnic tables. The most coveted sites are the 29 premium waterfront spots positioned directly on Lake Superior's rocky Union Bay shoreline, where campers fall asleep to the sound of waves. The campground provides full modern amenities including heated restrooms with flush toilets and hot showers, a sanitation station with two dump lanes and potable water, and a seasonal camp store offering supplies, gifts, and canoe/kayak rentals. A paved boat launch provides direct Lake Superior access, and an accessible fishing pier extends into the bay. The sandy Union Bay beach is a short walk away. From Union Bay, campers can access the park's 90+ miles of hiking trails, including routes to the iconic Lake of the Clouds overlook. The campground also hosts a disc golf course with rental discs available at the camp store.
