2 Best Sights in Door County, Wisconsin

Spanning 3,776 wooded acres along Green Bay, Peninsula State Park is a half-mile north of Fish Creek off Highway 42. Nearby bicycle-rental facilities make it easy to schedule an afternoon ride. A variety of activities within the park keep the most restless of outdoors enthusiasts happy, including an 18-hole golf course, bicycling and hiking trails, a beach, a lighthouse, White Cedar Nature Center, and Peninsula Players Theater. Spots at the 468-site campground book up quickly during the summer.

Life on the 912-acre, car-free Rock Island, home to this state park, is simple and rustic. Ferries depart daily from Jackson Harbor on the northeast tip of Washington Island. Only hike-in and backpack camping is permitted, although day trips are encouraged. Pottawatomie Lighthouse, on the island's far-northern tip, is Wisconsin's oldest lighthouse, fully restored to how it might have operated around 1910. Daily tours are led by live-in volunteer docents.
