How the Michigan DNR Booking Window Works

1
Pick your arrival date. The booking window opens exactly 6 calendar months before your arrival date. A July 15th arrival date opens on January 15th.
2
Note the day of the week. If your booking date falls Monday through Friday, the window opens at 8:00 AM Eastern. If it falls on Saturday or Sunday, it opens at 9:00 AM Eastern.
3
Prepare in advance. Create your MiDNRReservations.com account and save your payment information at least a week before your booking date. Know which sites you want before the window opens.
4
Be ready at opening time. At popular parks like Ludington or Wilderness State Park, sites sell out within seconds. Have the search pre-loaded and be ready to click at exactly the right time.
5
Missed the window? Set a CampDrop alert. People cancel Michigan state park reservations every day. MittenCamper watches MiDNRReservations.com around the clock and texts you the moment a matching cancellation appears.
