The Red trail in Whitfish Bay State Park is 2.8 miles long, but also has a shorter loop available. The trail takes hikers to "Old Baldy", the tallest dune in the park, which rises 93 feet above lake level. Old Baldy has an observation platform, for views of Lake Michigan and Clark Lake. A boardwalk and stairs lead to the top. A vehicle admission sticker is required on all motor vehicles stopping in state park, forest, recreation area and trail parking areas. Buy your sticker when you get to the park or in advance. Annual stickers offer admission to all state parks and forests for the calendar year.
