Although the park does not offer cabin facilities, look into Grand Mere State Park cabins located adjacent to the park, and immerse yourself in the park's diverse nature trails.
This two-mile trail is set along the park's dunes, offering scenic views of Lake Michigan. The trail is moderately tricky owing to the steep climb up Baldtop Dune, the park's highest.
This is the park’s main trail. Stretching for half a mile, it is paved and is ADA accessible. At the end of the paved trail is a sandy trail that heads west into the Lake Michigan sand dunes.
The rest of the park's four miles of trails are not marked, so keep in mind that if you're ready for a longer hike, you'll need a GPS of some sort. One trail you can find fairly easily is a mile long, running from the parking lot by Wishart Road to the start of the Nature Trail.
Aside from hiking, visitors can enjoy a range of activities. Just remember to come prepared from Grand Mere State Park cabins, as this undeveloped park offers no concessions or facilities.
Grand Mere State Park is along a major migration flyway, and thus birders flock to the park in spring and fall. You can spot over 250 species of birds in the area, including hawks, common loons, waterfowl, warblers, and herons.
The park attracts Nordic skiers (with their own skis, as there are no rentals) in winter, who enjoy the park's undeveloped state.
The park is home to three inland natural lakes, North Lake, South Lake, and Middle Lake. Middle Lake has a public boat launch. Visitors can enjoy swimming, water skiing, and tubing. Middle Lake also contains bass and span fish, for those interested in fishing.
With about a mile of beach right along Lake Michigan, in warm weather you and the kids can enjoy a day of swimming and playing on this sandy shoreline. Keep in mind there are no lifeguards on duty. Dogs are welcome, as long as they are leashed.
