If you are local to MI you've probably found many places with beautiful sand dunes. These dunes are still able to blow anyone's mind! This hike is 3.6 mile hard hike. The climb is the hardest part. You can just do the climb and still get the benefit of the beautiful views (which is more like .50 up straight up).
Health Tip: Be sure you are hydrated and physically fit to do this. The reward is great but the climb is hard!
