Haven't camped there yet, but sailed in the area for several years and loved it. There is a ton of hiking in the area, we took a tour around Cadillac Mountain and some of the surrounding area out of Bar Harbor, the Asticou Gardens at Northeast Harbor are beautiful. IMO 5/6 days in the area is plenty.
