The Dune Succession Trail is a fantastic one-mile loop that transitions from bare dunes to oak woodlands, with 250 stairs leading to stunning views of Lake Michigan and the Chicago skyline. Climbing the stairs to the top can be relatively challenging for some, but the incredible vistas make it well worth the trek!

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. Spot the skyline of Chicago 28 miles across Lake Michigan from the lookout point! https://www.nps.gov/indu/planyourvisit/wb16.htm
