About Seattle

Seattle, Washington sits at one of the most beautiful spots in the United States. Occupying a narrow isthmus between the Puget Sound and Lake Washington, it is the biggest city in the Pacific Northwest, with 780,000 people in Seattle and over four million people in the metro area. Seen from above, carpets of evergreen trees, pristine blue waters, and snowy white mountains surround the downtown's metallic skyscrapers, earning the city its nickname The Emerald City. On the ground, you will find a vibrant and cosmopolitan city.
