King County

King County is the largest county in Washington State by population, home to roughly 30% of the state's residents. It stretches from Puget Sound to the Cascade Range, encompassing the major cities of Seattle and Bellevue and their sprawling suburbs, as well as wide stretches of rural farmland and uninhabited mountain terrain.

Get in

By car

The major interstates are I-5, running north-south through Seattle to Snohomish County and Pierce County, and I-90, running east from Seattle through Bellevue and Issaquah to Snoqualmie Pass and Kittitas County. The notoriously congested I-405 splits off from I-5 at Tukwila in the south and Lynnwood in the north, serving Bellevue and the other cities of the Eastside. SR-167 is an alternate route from Tacoma to the south county, while SR-18 is a high speed bypass from north of Tacoma to I-90 east of Issaquah.

By plane

Seattle-Tacoma International Airport, (SEA ^IATA), called "SeaTac" by locals, connects Seattle to all regions of the world, with especially frequent transpacific routes. Competition is fierce and fares are low on service to the San Francisco Bay Area and Southern California.

By boat

• Washington State Ferries connect downtown Seattle to Bainbridge Island, to Bremerton, and to Vashon Island, and connects West Seattle to Vashon Island and to Southworth (Kitsap Peninsula). All ferries are for both vehicles and passenger except the ferry between downtown Seattle and Vashon Island.
• High Speed Catamaran Passenger ferries [1] connect Seattle to Victoria, British Columbia (Canada)

Sound Transit

Sound Transit, toll-free: +1-888-889-6368. Has regional public transit routes including Sounder trains, Link light rail, and express bus in King County (e.g. Bellevue, Federal Way, Kent, Renton, Seattle), Snohomish County (e.g. Everett, Lynnwood) and Pierce County (e.g. Puyallup, Tacoma). (updated Jun 2023)

• Link light rail operates in Seattle, traveling north to Northgate Mall and south to Angle Lake via Seattle-Tacoma International Airport.
• Sounder commuter rail service, operating weekday rush hours only, connects Seattle to Tacoma via Kent and Tukwila.

• Sound Transit has many convenient express bus routes that travel South (to Tacoma), East (Redmond, Bellevue), and North (Bothell, Lynnwood). Outside of the immediate Seattle-Bellevue area, many routes operate only during weekday rush hours. Check your schedules in advance, and beware of holiday service cutbacks. All Sound Transit routes have route numbers that are in the 500s.

By car

All but essential for reaching the outermost suburbs and mountains. In addition to the interstates, major routes include SR-520, linking Seattle's University District to Bellevue and Redmond; SR-18, a major freeway in the south county from Federal Way to Issaquah; and SR-509, the alternate route from the airport to Burien and Seattle.

Traffic congestion is a major problem in the Puget Sound area on all freeways and major roads. Avoid traveling during rush hour if you can, particularly along I-5 and across the Lake Washington bridges.

Lake Washington is crossed by two floating bridges: the I-90 bridge is free, but the SR-520 bridge charges a toll that varies by the time of day. There are no toll booths: unless you have a transponder, your license plate will be recorded and a bill will be mailed to you automatically in a few weeks. The long detour around the lake in either direction will usually waste far more time than you'll save in toll money.
