LANSING (AP) — An annual fee that allows unlimited access to Michigan’s state parks is rising by $1.

Starting March 1, it will cost $12 for the Recreation Passport when it’s bought with one’s license plate registration renewal. It’s the first fee increase in seven years.

The Michigan Department of Natural Resources said the fee change is due to a provision in the law that ensures the funding source keeps pace with inflation.

The fee will be $17 when a passport is purchased at state parks, DNR customer service centers or at a secretary of state branch outside the vehicle registration renewal process.

The fee provides access to more than 100 state parks and recreation areas, 140 state forest campgrounds, trails, historic sites and hundreds of boating access sites. About 94% of state park funding is from user fees and royalty revenues.

The fee for nonresidents rose to $34 this month.
