Portland Hillside
Fore Street, Old Port, and Congress Street Walk

Portland is so dense with elegant 19th-century urban architecture and waterfront views that any walk through the city is a scenic stroll. A couple of the standout areas are Fore Street along the waterfront, famous for its progressive food culture; the Old Port waterfront; and Congress Street, including the city's Museum of Art, City Hall, and other monumental buildings. These routes all pass waterfront and urban parks, with neat public sculpture and busy social scenes. See the attached map for points of interest.
