Van Buren Trail State Park, also known as Trail State Park, is an unimproved rail trail running along a former railroad right-of-way between Hartford, Michigan to just south of South Haven, Michigan in Van Buren County. It is 14 miles (23 km) long and mostly used by horse trail riders in the summer and snowmobilers in the winter. Terrain is flat with farmland and trees.
In 2004, Van Buren County took over operation of the state-owned trail after state budget problems. There is a trail pass system to pay for maintenance.
