It is in the Hiawatha National Forest (central UP of Michigan). I've done this once as a day trip.  All the lakes along the main NW to SE route can be paddled in one day.  No loops, just an in and out from the access. I entered from the west, though I think there is an access from the east side.  One large group was camped on the eastern most lake.  I remember that being the most "fishable" lake due to the perch population.  Some of the smaller lakes had appealing Quetico type campsites which were not overused.  Lots of maple & hardwood types so should be very colorful during October.  On Labor Day weekend, FH13 was closed at the US 2 junction.  So you may need to plan your access accordingly.
