The price of the Recreation Passport needed to enter Michigan’s state parks, recreation areas and forest campgrounds is going up $1 effective next year, The Associated Press reported.

The state Department of Natural Resources announced Wednesday (Nov. 14) that starting Jan. 2 the price will be $11, up from the current $10. The DNR says the increase is based on a requirement built into legislation that created the program that says the annual price must keep pace with inflation.

The state began selling the passports in October 2010 as a way of paying for park operations and maintenance. Motorists can buy them when visiting a park or renewing their vehicle licenses.

A related “Passport Perks” program includes discounts on goods and services from 1,100 local businesses to those with a Recreation Passport.
