Explore Seattle/Tacoma
Seattle is known as the Emerald City thanks to the vast evergreen forests that surround it. But it’s also sometimes called Jet City, thanks to its contributions to the aerospace industry. Both of these names are evocative of two of the area’s most popular attractions: the Space Needle and the pull of the great outdoors.
Who doesn’t think of the Space Needle when they imagine Seattle? If you’ve seen the landmark before, there’s still something new for you to explore—recent renovations offer iconic new views from amongst the Seattle skyline. The area also boasts plenty more to do. The Museum of Pop Culture is a can’t-miss attraction for anyone who loves Americana, television, kitsch, and entertainment. Lovers of the deep blue sea can get up close and personal with some of its inhabitants at the Seattle Aquarium. Science lovers can indulge their interests at both the Museum of Flight and the Pacific Science Center.
