We are planning a trip in Sept 2014 flying into Boston for a few days and then up to Arcadia NP with flying back home via Bangor. We think we might stay in Boston for 2-3 days and also stay in Arcadia for 2-3 days. We would like to see the key sites but also like to hike and do some kayaking. We are looking for suggestions of things to see and do but also some recommendations for places to stay.
Thanks

Welcome to Fodors!

It's Acadia...no r. We'll need to know what type of lodging you prefer, and an idea of how much you want to spend, in dollars.

Portland ME for great restaurants and city visit. You might want to take the mailboat trip to various islands in Casco Bay. IF you are lucky, (Sept might be too late) check lighthouse cruises available from the Maritime Museum in Bath ME.
Check out cruises from Portsmouth NH. Inland Rivers is fascinating.

Mid-coast Maine offers a lot of choices. Do not miss Mount Battie in Camden Maine. View from the top is incredible. You can also visit wineries in the area.

Hope you get some good recommendations for kayaking. It's very popular in New England. Saw a book on Maine Coastal Kayaking on Amazon you might like to read.

Some lobster shack type places might be open weekends only after Labor Day so be sure to schedule a visit. One of our favorites is Waterman's Beach near Rockland.

Sorry about the spelling. As for lodging my wife and I don't want to spend much because we prefer to be out and about. A nice hotel or a good B&B that is rustic would be nice. As for cost somewhere around $150/night. Are most recent trips have been to the NP's out west where we stayed at the historical lodges but we usually left around 8 AM and came back around 6. Hope this gives you an idea of the type of lodging we prefer.

Thanks

There usually isn't lots of info here about Acadia, but in case it helps, I've stayed here many times:

It's very rustic, and dog-friendly--not for everybody, but when you open the door in the morning you are looking at Cadillac Mountain across a big open field--priceless.

Liz, those cottages look great. Rustic is good. If you have basic kitchen facilities you can take advantage of some of the great farmers markets. Get a list from ME Dept of Ag. The one in Bath was great, also Brunswick.

Boston is a wonderful, smallish city to explore. You can walk the Freedom Trail, take a DUCK TOUR (lots of fun), visit Chinatown, and North End (Little Italy), the waterfront, maybe see a Red Sox game, take a harbor cruise. If you like art, don't miss the Museum of Fine ARts, and the Elizabeth STuart Gardner museum. Hotels are pricey, though, so I don't have suggestions for them.

Lots of places to stay in Acadia. Try: acadiamagic.com. We've stayed at many places, including the Black Bear campground.
Bar Harbor Regency, Wonderview, and some others. Not really, rustic though. We did stay in a log cabin in Bernard. The website is boathousewaycottages.com The Bar Harbor Inn is a luxury hotel, but for lunch or a drink it's wonderful. Right on the harbor. There is a nice waterfront terrace, and you can show up in shorts.

You will enjoy both places, and if you like the outdoors, you will wish you had more time in Acadia National Park.
