My favorite place to visit in Maine is Bar Habor/Acadia National Park. It's a great place to camp also, with free bus rides from the camp area to the town. The free bus service also loops around Acadia Nat'l Park, so you really don't need your car to get around, if you stay in one of the many hotels or inns near the town. Lots of beaches, hiking, boat rides and lobster boat trips, light houses, shopping, lobsters and great ice cream. Shops are open at night in summer.
Porcupine Islands, viewed atop Cadillac Moutain.
Lots of hiking available in Mt. Acadia National Park.
Bed and breakfast inn.
Atlantic Ocean, just as beautiful as the Pacific Ocean on the west coast, but much colder water.
Most of the restaurants in Maine serve lobsters.
There are some really good ice cream shops in Bar Habor. Here's a red lobster holding a triple cone. (BTW, you have to try their blueberry ice cream. Maine is famous for lobsters and wild blueberries.)
Lots of tiny fish in the shallow water, but alas, also some leeches!
OGUNQUIT, Maine
Photos below are at Ogunquit, a coastal town 4-5 hours south of Bar Harbor.
At Perkin's Cove.
On Marginal Way, a one-mile trail connecting Perkin's Cove to downtown, Ogunquit.
Advertising on the stairs.
Shops on stilts, probably covered with water during high tide.
Really good clam chowder and spicy haddock soup at Perkin's Cove.
Dinner in Ogunquit at Mike's Clam Shack - it was super crowded despite being a large restaurant.
Typical New England fried seafood, covered with fried onion rings.
Scallops, whole clams, shrimp and fish - in order of my taste preference.
