Harrison/Naples area is pretty - lots of lakes, lots of antique shops, a few camping areas. Big difference in population between tourist season (which , around here, is summer) and the rest of the year.
I'd caution that the area is good for someone who is content to be quite a distance from cultural hubs - there aren't a lot of options as far as restaurants/theatres/events. It's a remote area from Portland and from North Conway. But the area is beautiful, and if you're looking for the feeling of "getting away from it all," I think that would probably fit the bill.
