What are your interests? Along the coast we like to go to Eastport, Camden Hills/Rockport, York, Sacaborough, Bar Harbor. When visiting away from the coast we like the Moose Head Lake area and Sabago Lake Region. If you go to Eastport, bring your passports so you can visit Campabello Island, Canada. We decide on where we are camping depending on if the grand kids come along. Check out whale/puffin watches and ride a schooner. Plenty of great moose watching areas in the Moose Head area.
Great outlet shopping in the Kittery area. LL Bean is in Freeport.
