These enormous dunes left by glacial action are located at the eastern end of the park. Access via the 1/3 mile (one-way) Dune Trail beginning at the Sable Falls parking area, one mile west of Grand Marais along Alger County Road H-58. Be prepared to walk partly uphill in soft sand. Please do not step on any vegetation. No pets, and no sledding or skiing on the dunes.
Five square miles of Grand Sable Dunes are perched atop the 300-foot high Grand Sable Banks. A portion of the Grand Sable Dunes is set aside as a Research Natural Area.
