The Washington State Department of Transportation’s website (www.wsdot.wa.gov ) is a good one-stop place for links to the various auto, ferry, bus, air, bike, and train options around the state.
Washington’s two major airports are Seattle-Tacoma International (Sea-Tac) and Spokane International, served by nearly all the major carriers and a handful of smaller airlines. Horizon Air (a subsidiary of Alaska Airlines) (800/252-7522, www.horizonair.com ) is the big “little” airline, connecting many Washington cities including Seattle , Spokane , Bellingham , Lewiston, Pasco , Port Angeles , Pullman, Walla Walla , Wenatchee , and Yakima .
Amtrak (800/872-7245, www.amtrak.com ) serves Washington with two routes. The north–south route along the West Coast is aboard the Coast Starlight, which has service several times a day to Seattle , Tacoma , Olympia/Lacey, Centralia, Longview /Kelso , Vancouver , Portland, and south to Los Angeles. The modern and stylish Cascades provides daily train connections north to Vancouver, B.C., via Edmonds , Everett , Mount Vernon , and Bellingham . The east–west route to Chicago is on the Empire Builder, which has daily service to Spokane, then turns southwest to Portland with stops at Pasco , Wishram, Bingen/White Salmon , and Vancouver, or to Seattle via Ephrata, Wenatchee , Everett, and Edmonds.
Note that Amtrak requires advance reservations; you can’t just go down to the station and climb aboard.
Highways and roads are generally well maintained in Washington. The main approaches to Washington are I-5 from the north or south in the coastal area, I-90 from parts east, and I-84 from eastern Oregon.
