You’ll soon have to pay a fee to enter Indiana’s only national park. Indiana Dunes National Park will have an entrance fee beginning March 31. Entry to the park will cost $15 per person, $20 for a motorcycle, or $25 per family/carload. A $45 Indiana Dunes National Park Annual Pass will be available starting March 1. Holders of the following land passes will not be required to pay an entry fee: Annual Pass, Senior Pass, Veterans, Military and Gold Star Family Pass, 4th Grade Pass, Access Pass (for permanent disability), and the Volunteer Pass. The entry fee is only for the national park and does not change the fee the state collects for Indiana Dunes State Park.
