Challenge your calves and climb three separate dunes in the Indiana Dunes State Park: Mount Tom, Mount Holden, and Mont Jackson. Stop by the visitor center to get your completion prize.
See five buildings, all from the Homes of Tomorrow Exhibition of the 1933 Century of Progress World's Fair which took place in Chicago. They were originally intended to display the future of housing, and today are private residences with nearby plaques.
The name of the park's highest dune, and given the height of the dunes around the beach, this beach is the most strenuous to reach. The views from the top of the "mountain" are quite nice, and reward the heavy breathing you'll do on the trail to the top. Don't let the fear-mongering signage dissuade you, though, the trek really is not too hard, as it is a gentle incline heading up. Walking in sand even on a slight incline, though, is a good deal harder than on solid ground. The drop from Mt Baldy to the beach is extreme, and goofing around on the steep slope is a bad idea—sand is soft, but you could pick up enough speed rolling down to seriously injure yourself. There is an alternate path further back along the Mount Baldy trail that will take you to the beach without the sharp incline. Mount Baldy is suffering from increasing erosion, in part due to off-trail hiking. Please only hike the main trail on Mount Baldy.
