Airports & Airlines
Aside from the big national carriers, the small regional Cape Air (www.flycapeair.com) has daily flights connecting Boston with Augusta (65 minutes), Bar Harbor (80 minutes) and Rockland (65 minutes).
Departure tax is always included in the cost of a ticket.
Sharing a border with Canada, Maine has two dozen places to cross. Generally, crossing the US–Canadian border is straightforward, though the length of the lines can be a hassle. All travelers entering the USA are required to carry passports, including citizens of Canada and the USA.
Concord Coach Lines (www.concordcoachlines.com) operates daily buses between Boston (including Logan Airport) and Portland, continuing on to Midcoast Maine towns (Bath, Belfast, Brunswick, Camden, Damariscotta, Lincolnville, Rockland, Searsport and Waldoboro). There are also services connecting Boston, Portland and the inland towns of Augusta, Waterville and Bangor. Two services a day link Portland with New York City.
Greyhound (www.greyhound.com) stops in Bangor, Portland, Bath, Rockland and various other towns.
Car & Motorcycle
Except for the Maine Turnpike (I-95 and I-495) and part of I-295, Maine has no fast, limited-access highways. Roads along the coast flood with traffic during the summer tourist season. As a result, you must plan for more driving time when traveling in Maine.
Hitchhiking is never entirely safe, and we don't recommend it. Travelers who hitchhike should understand that they are taking a small but potentially serious risk.
Crossing the US–Canadian border can be a challenge for hitchhikers. Most drivers will not want to take the risk or endure the hassle of transporting a stranger across the border. It is possible to cross the border on foot, although border guards are likely to be suspicious: expect extensive interrogation. Non-US citizens will likely be requested to prove their means (ie access to money) and their plan to exit the country (ie a return ticket).
Hitchhiking is legal in Maine, as long as you stay off the traveled part of the road or on the shoulder. On interstate highways, hitchhiking is restricted to on-ramps.
According to Hitchwiki (www.hitchwiki.org), Maine ranks as 'easy' on the Ease of Hitchhiking map. Neighboring Vermont is cited as the easiest place to thumb a ride in the entire country.
The Downeaster, run by Amtrak (www.amtrak.com), makes five trips daily between Boston and Portland (2½ hours). A couple of these services extend to Freeport and Brunswick, too.
In summer, Bay Ferries (www.ferries.ca/thecat) operates the CAT service, sailing daily between Portland and Yarmouth, Nova Scotia (six hours). Discussions are underway to end the service in Portland and open a ferry line between Bar Harbor and Yarmouth instead.
