Portland, Maine punches way above its weight. It's a small city — fewer than 70,000 people — with a big reputation for food, art, history, and one of the most walkable waterfronts on the East Coast. Lobster rolls, yes. But also world-class restaurants, microbreweries tucked into old warehouses, century-old lighthouses, island ferries, and cobblestone streets that make every stroll feel like you stumbled into a movie set.
