Mount Jackson, Mount Holden, and Mount Tom loop

This loop is famously known as the "3 Dune Challenge" and is considered difficult due to its terrain. It involves hiking over deep, loose sand, which makes ascents strenuous, often described as "two steps forward, one step back." While relatively short, it's a significant leg workout.

The terrain is predominantly deep, loose sand, especially on the dune ascents. However, the trail also winds through forested areas, offering a unique contrast of woods on sand dunes. The ascent of Mount Tom, the tallest dune, features a well-maintained staircase, which can make that section slightly easier.

From the summits of the dunes, you'll be treated to expansive views of Lake Michigan. On clear days, the skyline of Chicago can also be seen in the distance. The route itself offers diverse landscapes, including distinctive dune forests and views from Mount Jackson, Mount Holden, and Mount Tom Viewpoint.
