    Explore Seattle/Tacoma

    The Pacific Northwest is calling. Trade the desert of the American Southwest for the shores of the Puget Sound, and get ready to take in the sights. The Seattle/Tacoma area is home to mountains, vast forests of evergreen trees, and, of course, the Pacific Ocean. Go for a hike, or a boat ride, or camp out amongst the stars. There’s no one way to take in the Seattle scenery, flora, and fauna. Consider a tour of Puget Sound, or guide yourself on an exploration of the bays and harbors from Seattle to Tacoma. Spend a day heading to Mount Rainier National Park and climb, hike, bike, or just picnic. Visit the Tacoma Narrows Bridge and Vashon Island at Point Defiance Park. Try to fit each of these locations in on your trip, or plan to come back time and time again.

    Hungry for more? You’ll certainly be hungry for food after all that hiking, biking, or climbing! Seattle is a great destination for foodies, thanks to its range of offerings from street food to haute cuisine. Fresh seafood abounds—and if you’re at some famous markets, they also fly! And who could forget the deep, rich coffee heritage of the Emerald City? Grab a cuppa from the landmark outposts of world-famous mud purveyors, or stop into a hole-in-the-wall coffee bar and discover something special.
