>>2757969Hit Portland on the way up or back if you like good food and beer, so many great restaurants and breweries there. Portsmouth NH is also a great spot for seafood and has lots of colonial/federal architecture and history.
Acadia will probably be extremely busy, especially on weekends. I would hike/visit there on weekdays to cut down on the crowds. Pick up any supplies you need in Ellsworth on the way in. Definitely do a sunrise hike/drive up Cadillac Mountain as its the first place in America to see the sunrise this time of year. Jordan Pond is another beautiful but busy short hike worth doing. A loop on the Great Head trail is nice and will get you a good sense of the Maine coast. Also be sure to visit the "quiet" western side of the island where most locals and fishermen live. Bass Harbor light and Ship Harbor are very scenic and don't get the same level of crowd that Bar Harbor does.
Baxter State Park and Mount Katahdin are only about 2.5 hours away from Acadia. Great place to see wildlife, especially moose. Katahdin is (IMO) the best hike in New England, but be advised if you want to hike it you either need a reservation (which are tough to get) or you'll need to show up at 5AM at the gate and wait til 7AM when the rangers start letting folks take no-show's spots (pretty much always guaranteed). Baxter is also awesome for fishing and camping if you're into that.
