There is no shortage of fun things to do in Seattle, whether your tastes run to the educational, natural, or quirky. Within walking distance of the convention center, check out Pike Place Market, one of the country's oldest continuously operating farmers' markets, for a variety of produce, food, art, and crafts. Also close at hand are the Seattle Art Museum, the Museum of Pop Culture (MoPOP), which includes the Science Fiction Hall of Fame, the award-winning Seattle Public Library, and the Olympic Sculpture Park. A little farther afield, you'll find Elliott Bay Bookstore, the Museum of Flight, the Pacific Science Center and much more.
From the Seattle waterfront, you can take a variety of tours on the water, including boat rides through the Ballard Locks, tours of Elliot Bay, and day trips to Blake Island.
A bit farther afield but still in Seattle, you’ll find the Museum of History and Industry (MOHAI), the Woodland Park Zoo, the Museum of Flight, and the Burke Natural History Museum. Local neighborhoods add personality, fun shopping, and more great restaurants &emdash; check out Fremont, the University District, or Ballard.
For people with a few extra days, Olympic National Park, Mount Rainier National Park, and Mount St. Helens National Volcanic Monument are all in day-trip range from downtown. The Hoh Rain Forest is stunning, as is the Olympic Hot Springs Resort, a wine trail, several cideries, and again, plenty of opportunities for amazing natural views.
