Reservations will be required for all campsites in Sleeping Bear Dunes National Lakeshore starting April 1.
Most of the sites at Platte River Campground already took reservations, but D.H. Day Campground was entirely first-come first-serve, leading to long lines overnight as people waited to nab a site. The National Park Service says the change to reservations will fix those long lines.
Park Superintendent Scott Tucker announced all campsites would move to a reservation system more than a year ago, but it was delayed in November after the contractor overseeing the switch said it needed more time.
Reservations can be made at recreation.gov. Both campgrounds open May 1.
