Grand Mere State Park
Geography
The 985-acre (3.99 km) park is mostly wooded and has three geologically ancient inland lakes, left behind as the glaciers receded during the last ice age. At one time there were five such lakes, but two of the lakes have disappeared as a result of aquatic succession, and the remaining three can be seen to be slowly disappearing today.
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.
Activities and amenities
The park offers swimming, hiking, picnicking, boat launch, and cross-country skiing.
The park has almost two miles of sandy beach, which can be reached only on foot by climbing over steep sand dunes. There are many trails for hiking and cross-country skiing, but most are neither posted nor maintained. (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.
