Grand Sable Dunes - National Parks Gallery

The Grand Sable Dunes west of Grand Marais are one of the major features of the park and are among the best examples of perched dune systems in the world. Rising more than 300 feet above the lake, the Grand Sable Dunes are the highest formation in the park. They comprise five square miles and contain uncommon plant species and communities, including the richest orchid flora in the Great Lakes and the federally endangered Pitcher's Thistle.
