Excellent choice! It is arguably the most beautiful state east of the Mississippi. Bar Harbor, Acadia National Park, and Camden make the short list. Portland is a great foodie town if restaurants are your thing. They also probably have more craft breweries per capita than anywhere I’ve been. Lots of history there, too. Take a tour of Casco Bay. Hit as many lighthouses as you can. They’re all different. Take in as much of the rugged coastline as you can as well. Camden is an absolutely beautiful quintessential New England harbor town. You can easily spend a day there just strolling the streets, hitting the shops, eating and walking around the harbor. Acadia is just as impressive as many of the national parks out west and spills into the Atlantic. Do a couple hikes and take in the views. Whatever you decide to do while you’re there, I doubt you’ll be disappointed. Enjoy!
