It is a nice 70 mile loop. There is a nice topo map and guidebook available from the Pigeon River Country Association. In the past there have been problems with loosing the trail where they have done some clearcuts and some confusion with horse trails in the area. Water is a little scarce in some areas. Lots of trip reports available with a Google search. It is not too strenuous but do not expect to have a blaze in view at all times. I have hiked it at least twice in four days.
