Downtown Portland offers all the features of a mid-sized downtown area, including restaurants, shops, theaters, concert halls, hotels, and a convenient bus and rail service. Specific highlights of the area include the Portland Art Museum, Tom McCall Waterfront Park on the Willamette River, and Pioneer Courthouse Square. Although it is the urban heart of Portland, the downtown area still has many unique and charming features which distinguish it from typical urban areas, such as parks, sculptures, plant life, and numerous fountains. These special touches, along with its cleanliness, help make Portland stand out as one of the nation's most livable cities.
