Things to Do in Seattle

Pike Place Market

The Pike Place Market is a public market in the heart of the city. This downtown public market has been in business since 1907. It’s a year-round farmers market and a visual riot of vegetable, seafood, cheese and flower stalls along with handicrafts and tourist-friendly knick-knacks. And, of course, the flying fish. For less crowd, take the stairs to “Down Under,” a wood-floored maze of small shops beneath the main-level market. And walk into the shops and stalls across the street from the main market, including “the original” Starbucks (moved here after nearly five years of its opening in 1971, but retains its vintage look).

Olympic Sculpture Park

At the Olympic Sculpture Park, visitors can capture wonderful views of the city, harbor, and mountains. And it’s free. This outdoor sculpture garden is spreads over approximately 9 acres of area. Here one can see various artwork including Alexander Calder’s “Eagle,” and six tons of red-painted steel that looks like an abstract soaring bird. For a longer lovely walk, stroll along the 1.2-miles of waterfront path in the nearby Myrtle Edwards Park.

Seattle Ballooning

Get a birds-eye view of downtown Seattle and Mt. Rainier from aboard one of Seattle Ballooning’s beautiful hot air balloons. Book a semi-private or private flight depending upon the occasion and indulge in one of the most memorable experience. End of the flight is celebrated in a traditional French style: with a champagne toast, fresh-baked croissants, triple-cream brie, and organic strawberries.
