Destination guide
Seattle: Coffee, mountains and Puget Sound
Seattle is the Pacific Northwest's gateway: Pike Place Market, the Space Needle and ferries across Puget Sound, with Mount Rainier and the Olympic Peninsula a couple of hours away. Sea-Tac is a Delta and Alaska hub with light rail downtown.
Best time to visit: July–September is dry, sunny and gorgeous — and the most expensive. May–June and late September are good compromises. October–April is gray and drizzly but cheap.
