    Seattle, the Romantic City on the Harbor

    Located in the northwestern part of the United States, near the border of the United States and Canada, Seattle is a beautiful city with abundant natural resources such as mountains, lakes, harbors, and rivers. The city experiences the perennial veil of rain, giving it a romantic and beautiful atmosphere, which also invites its residents to have a slow and relaxed pace of life. Additionally, titans of industry, such as Boeing, Microsoft, and Amazon have set up their headquarters here, making Seattle an important city in the global technology development.

    Exploring Seattle

    The Space Needle is an iconic landmark in Seattle. The observation deck and the rotating glass floor at the top provide a spectacular view of the cityscape of Seattle, where you can enjoy the view of Mount Rainier during the daytime, the sunset over the bay in the evening, and the sparkling lights of the city at night; and Pike Palace Market, a tapestry of delicious food, charming history, and traditions, is a great place for enjoying cuisines and shopping. The unique fish-throwing show by fishmongers makes the market livelier and more attractive. With its convenient location, Pike Palace Market is full of seafood restaurants, so you can always pick one to enjoy the fresh fish dishes. Pike Place Chowder is also a must-visit restaurant in Pike Place Market. The rich, creamy chowder is delicious either on its own or with sourdough bread. The Gum Wall is a special attraction created by locals and travelers from all over the world, with colorful chewing gum crumbs stuck to the wall, giving it a sense of historical significance and epoch. In addition, the original Starbucks store is located near Pike Place Market and retains its original logo, making it a worthwhile visit for coffee lovers and non-coffee drinkers alike!

    Seattle boasts an abundance of natural resources, having Mount Rainier, Olympic National Park, Twin Falls, and Snoqualmie Falls, with forests, mountains, waterfalls, and glaciers to satisfy all kinds of outdoor enthusiasts. The whale-watching season starts from March to October every year. The San Juan Islands and Lime Kiln Point State Park are popular whale-watching destinations. From April to October, many visitors take a cruise from Seattle to Alaska to see the stunning glaciers and explore the charming port city along the coastline.

    The best travel season

    Affected by the topography, Seattle has more rainy weather throughout the year. June to August is relatively popular travel season because of more sunny days and longer daytime, which is suitable for outdoor activities such as hiking, cycling and boating.

    City transportation

    Besides driving, Seattle's public transportation network is well-connected. Travelers can take MonoRail, Link Light Rail, Seattle Streetcar, and Sound Transit Express Bus to almost all destinations in Seattle. "ORCA Card" and day-passes also makes transportation easier.
