Where do you rent a boat for lime island Michigan state park?

You might try Karens Rustic Cabins in Raber. I know she used to rent small boats out but am not sure if she still does. There were several cabin owners that also used to rent boats north of the town of raber on the point. Karens is the first place to try she is very helpful and will know if anyone around has boats for rent. I lived a great deal of my life on Lime Island and I'm sure you will have a great time. Also you can try searching http://www.rentalboatcharters.com - the boat rentals directory.
