Grand Mere State Park is a public recreation and nature preservation area in the southwestern part of theU.S. state ofMichigan nearStevensville. Thestate park is located adjacent toInterstate 94. Protected fromLake Michigan by the dunes to the west, the park has many natural features not found throughout the rest of the state.[3] In 1968 it was designated aNational Natural Landmark.[4]
The 1,100-acre (4.5 km2) park is mostly wooded and has three geologically ancient inland lakes, left behind as the glaciers receded during the lastice age.[5] At one time there were five such lakes, but two of the lakes have disappeared as a result ofaquatic succession, and the remaining three can be seen to be slowly disappearing today.[6]
The dunes protecting the park also create a relatively cool environment that supports plants not normally seen in southern Michigan, some of which are classified as rare, threatened or endangered.[6]
The park offers swimming, hiking, picnicking, boat launch, and cross-country skiing.[3]
The park has almost two miles of sandy beach, which can be reached only on foot by climbing over steepsand dunes. There are many trails for hiking and cross-country skiing, but most are neither posted nor maintained.[6] (Biking on the trails is prohibited.) The trail conditions vary from loose sand to hard packed dirt. There are many hills including a large sand dune that was once used for off-road vehicles. Access to the dune by large, four-wheeled vehicles has been blocked with guard rails.
