Plan a trip to Seattle

Seattle is a city that blends bold innovation with the beautiful natural surroundings under the watchful eye of Mt. Rainier. Founded in 1851 as a lumber town, it has grown into a hub for tech, art, and culinary creativity. It is now home to global tech giants like Microsoft, indie musicians, and visionary chefs alike. But what truly sets Seattle apart is how seamlessly the outdoors flow into urban life. You can kayak on Lake Union by morning, sip fresh-roasted coffee downtown by afternoon, and watch the sun set behind the Olympic Mountains by evening. It’s a city of contrasts and connections—and there’s no place quite like it.


Things to do in Seattle

  • Wander through Pike Place Market, where fresh fish, flowers, and handmade goods fill the air with color and scent.
  • Take in sweeping views of the skyline, Mount Rainier, and the Space Needle from Kerry Park on Queen Anne Hill.
  • Paddleboard or kayak across Lake Union for a fresh perspective on the city.
  • Join the rowdy fans at a Seattle Seahawks or Mariners homegame
  • Explore the Seattle Art Museum and its waterfront Olympic Sculpture Park with views of Elliott Bay.
  • Ride a ferry across Puget Sound to the San Juan Islands for whale watching, biking, and local cider tasting.
  • Stroll around Green Lake or hike one of the nearby trails for a dose of urban-accessible nature.

Best time to travel to Seattle

The best time to visit Seattle is from late spring through early fall (May to September), when the weather is mild, skies are clearer, and the city’s parks, festivals, and waterfront shine. Summer days are long and perfect for hiking or ferry rides, while fall brings crisp air and vibrant foliage. Winters tend to be rainy, but they’re also cozy—perfect for exploring museums, coffee shops, and indoor markets.
