The builder, General Peleg Wadsworth, was a hero in the Revolutionary War, and a grandfather to poet Henry Wadsworth Longfellow. The two lived in the house together, and it remains one of New England’s more famous architectural artefacts. Reopened in 2002, the home is part of the Maine Historic Society and is open year-round for travellers.  Harbor side: A mile in length, the Harbor side begins at Casco Bay Lines ferry terminal (at the corner of Commercial and Franklin Streets). For fitness freaks the paved paths allow convenient room for walking, running, and biking with views of the islands. With a 68-acre hillside span of greenery that extends to the water, the Harbor side is your perfect outdoor daytime destination to get the best of the land and the sea.  Portland Sea Dogs: Take in America’s pastime after your flight to Portland lands. The Portland Sea Dogs are a Double A baseball team, affiliated with the World Series Champion Boston Red Sox. Spend an afternoon at the Sea Dogs game for a perfect summertime activity. Park your family on one of Hadlock Field’s aluminium benches, get some game-time grub, and watch as young hopefuls swing their way toward the pros.
