Milliken State Park in Detroit

William G. Milliken State Park and Harbor is a 21-acre green oasis in the heart of Detroit providing opportunities for picnics, walks, and shore fishing along the Detroit River. There is a wetland area and trails that hook up to the Riverwalk and a replica lighthouse of the one in Tawas Point on Lake Huron. Established in 2004, this is Michigan's 97th state park and the only one set in an urban area. There are over 50 spots for boats to tie up, right next to Chene Park.
