Explore Seattle/Tacoma

Take an unforgettable trip to the Pacific Northwest and visit Seattle! Enjoy the scenery as you take in the sights of mountains, evergreen forests, the water, and so much more. Whether you choose to climb mountains or eat your way through the city, there’s no wrong way to do a visit to Seattle. Take a breath of fresh air, look over the city from the Space Needle, and make this a trip to remember.

Get your steps in by walking along some of the most scenic trails of the Pacific Northwest. You have several options when traveling to Seattle, but taking a tour of Puget Sound is an absolute must. Take in a variety of natural formations, from bays and harbors in Seattle and Tacoma, to other smaller islands. You’ll be astounded when you gaze at the crystalline waters. Take a day trip to Mount Rainier National Park for mountain climbing, biking, and hiking alike, or walk through Point Defiance Park. There you can enjoy views of Tacoma Narrows Bridge and Vashon Island. No matter where you go for the day, there are always plenty of stunning views and photo-ops for those interested in being with nature.

Of course, all of that hiking is sure to work up an appetite, which is why Seattle is also the perfect destination for seafood lovers and foodies in general. Make your way around the city and sip some of Seattle’s best coffee, or slurp some of the freshest oysters the West has to offer. Visit large farmer’s markets throughout the city, get a taste of different cultures by exploring various foods from world-famous dumplings to ramen, or chow on some chowder fries. Wherever your trip through Seattle takes you, be sure to put away your screens and take in the beauty this place has to offer.
