The Dune Succession Trail (Loop 1) highlights the four stages of dune development within its one-mile length. From the parking lot, follow the road north, toward the lake and look for the trail to pick up to the west of the bathhouse. This scenic, but strenuous, trail includes a climb up 270 stairs for a spectacular view of Lake Michigan and Chicago. Support the restoration effort in the fragile dunes and ponds by remaining on designated trails.
