This park is easily accessed over a 7-mile paved causeway, or by boat and an abundance of flora and fauna, a bison herd, and numerous migrating birds are some of the things that await you. The visitor center offers information on the island's unique biology, geology and history, and some of the amenities include white sandy beaches, a sailboat marina, nearly 40 miles of hiking and multi-use trails, wildlife viewing, picnicking, and, because of the distance from the city and its lights, stargazing. Hours vary throughout the year. Camping is allowed in designated areas only, and they offer modern restrooms, showers, a food service area, and drinking water. Campers do not have to pay an additional day use fee for the park. There are no electric or water hookups at the campgrounds.
