A sandy footpath winds its way up a dune through oak savanna

Formerly Inland Marsh. A nice oak savanna with wet areas interspersed; trails pass over dunes formed millennia ago when the water level in Lake Michigan was much higher. Aside from the large paved parking lot and signage there are no facilities. A sandy trail heads south from the parking area, passing scattered trees and prickly pear cactus. After about a half mile, the trail turns west and climbs a short dune before connecting with a figure eight that winds its way over and between a series of dunes covered with oak savanna and intervening wetlands. Look for lupine, blue-eyed Mary, and wild columbine in May; bracken fern will be abundant later in the year. Highway, train, and aircraft noise can be annoying, but you’re not likely to encounter many pedestrian visitors.
