Natural Features
Known for its spectacular waterfalls, idyllic beaches, scenic hiking trails and tranquil campground, the Black River Harbor Recreation Area is a popular destination throughout the year. Originating in Wisconsin, the Black River flows through forested areas of large pine, hemlock and hardwood trees. The River has a series of scenic waterfalls as it drops in elevation to meet Lake Superior. Tannin (tannic acids) from hemlock trees is what gives it its unique color.
Nearby Attractions
A historic pavilion built by the Civilian Conservation Corps is located in the recreation area next to the campground. The recreation area includes a large picnic area and Black River Harbor that has fishing charters available and in itself is a scenic area to explore. Trails run adjacent to the Black River and lead to several waterfalls. A foot bridge and short walk will take you across the Black River to Lake Superior and the sand beach swimming areas.
