The Indiana Dunes is one of the most biodiverse areas in the United States, and we’ve made a self-guided tour for you to enjoy what mother nature has uniquely provided us. Welcome to the Discovery Trail.
Nestled in northwest Indiana, on the shores of the massive freshwater sea of Lake Michigan, is a remarkable place, a unique landscape carved by immense glaciers during the last ice age. As these frozen giants slowly advanced and receded, the ground beneath them shifted violently. And in their wake, they left behind a cornucopia of natural wonders, from sandy beaches and majestic dunes to sprawling wetlands and lush forests.
