In addition, large portions of this area are covered by the Manistee National Forest and the Huron National Forest. In the former, a unique environment is present at the Nordhouse Dunes Wilderness. This relatively small area of , on Lake Michigan's east shore, is one of few wilderness areas in the U.S. with an extensive lake shore dunes ecosystem. The dunes are 3500 to 4000 years old, and rise to nearly higher than the lake. The Nordhouse Dunes are interspersed with woody vegetation such as jack pine, juniper and hemlock. Many small water holes and marshes dot the landscape, and dune grass covers some of the dunes. The wide and sandy beach is ideal for walks and sunset viewing.
