free State park passes
Have fun in the great outdoors of the Great Lake State!
MI Big Green Gym passes allow one vehicle into a state park for one day, for free. The passes may be used June 1 to October 1. The MI Big Green Gym program is designed to promote outdoor fitness and demonstrate just how easy it is to get out, get active and get healthy. The MI Big Green Gym initiative is a partnership between the Michigan Recreation and Park Association, Blue Cross Blue Shield of Michigan, and the Michigan Department of Natural Resources. MI Big Green Gym is as close as your nearest state park and is available for free thanks to more than 400 Michigan public libraries participating in the program.
