Indiana Dunes National Park

IN
Lake Michigan's might has influenced Indiana Dunes for millennia. Wind and waves have shaped the land, leaving a rich mosaic of habitats along these 15 miles of Indiana coast. Over 50 miles of trails lead through shifting sand dunes, quiet woodlands, sunny prairies and lush wetlands. Known for its striking plant and bird diversity, it's easy to find inspiration throughout the park’s 16,000 acres.
