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.

Prefer terra firma to the air? Exploring the vast outdoor wonders surrounding Seattle may be more to your liking. The area is home to mountains, forests, and, of course, the Pacific Ocean. Go for a hike, or a boat ride, or camp under the stars. Consider touring Puget Sound, or spend a day at Mount Rainier National Park and climb, hike, bike, or just picnic. Visit the Tacoma Narrows Bridge and Vashon Island at Point Defiance Park.

When you deplane at Seattle-Tacoma International Airport, you’ll actually find yourself in the inner-ring suburb of SeaTac—the airport’s very own home. Grab a rental car, call a rideshare, or take advantage of the light rail or bus—it’s time to get going!
