Seattle is the primary international and domestic gateway to Washington State and the lush Pacific Northwest, as well as Canada and Alaska. At various points throughout the city, visitors can board the famous monorail to the Seattle Center, home of the Space Needle, the Pacific Science Center, the Seattle Repertory Theater, Pacific Northwest Ballet and the Opera House. The Waterfront area is full of unique maritime attractions and is a good place to enjoy the views and fresh air of Puget Sound from Waterfront Park or to board a Washington State Ferry to local islands. North of First Avenue is the Denny Regrade area or Belltown, the inner city’s entertainment quarter, full of art galleries and jazz clubs.
