The park, established in 1963, has picnic areas with tables, grills, water and toilets; a campground with drinking water, showers and toilets; an indoor camp for nonprofit groups; an outdoor group camp; and more than 9 miles (14 km) of trails, including nature trails. The park is open year-round, though winter visitation is mostly limited to hunters, snowshoers, and cross-country skiers.[2]
All vehicles are required to purchase an admission pass, though pedestrians and bicyclists may enter free. To reach the park, visitors must take a 20-minute ferry ride from Bayfield, then travel approximately 5 miles (8.0 km) east on Highway H.[2] Big Bay State Park is 1 of 3 Wisconsin State Parks that one would have the best view the Milky Way from, in regards to available Wisconsin State Parks.[3]
