ST. PAUL -- Campers will be able to make reservations at hundreds of previously "first come, first served" Minnesota state park campsites starting this week.

The Minnesota Department of Natural Resources says access to those additional sites will open not just for Memorial Day weekend but for the entire camping season at each park. Those sites typically make up 25 percent to 30 percent of the total sites at each campground.

The DNR said it will also start accepting same-day reservations with no reservation fee at most parks for travelers who show up spontaneously. Previously, campers had to reserve a site by midnight the night before arrival day.

Campers can check the DNR reservations site for availability and to make reservations.
