It's fun. It's definitely not the most remote 100-mile stretch in Maine, but it is fun. There are a number of logging roads that make access easier then you would think. The southern section-Barren-Chairback and White Cap-are the difficult pieces, but with some really great views and remote ponds down off the trail. After that the trail starts winding around these massive ponds and the hiking is fairly easy. The ponds all seemed to have lovely beaches, so don't be afraid to sit back and enjoy yourself. Antlers Campsite, which is north of the Jo-Mary Road, was one of the nicest campsites on the entire Appalachian Trail, and I unfortanately hit it at about ten in the morning and hiked on. Make sure you bring something for bugs. And have fun, because it's a great section.
General advice-if you want to peakbag White Cap, drive in from the west, park at the gate and walk in on the logging road until you reach the trail crossing. If takes hours to find the road from the east.
