Arriving by rail from the airport to Seattle Center

After choosing a Seattle hotel that accepts 18-year-olds, you decide whether to use an airport rail route with two handoffs. The pedestrian connection from the Seattle-Tacoma International Airport terminal to SeaTac/Airport Station uses a parking-garage walkway, and you cross it before boarding light rail.

From SeaTac/Airport Station, take the northbound Sound Transit 1 Line light rail to Westlake Station. Use Exit A2 to reach the Westlake Center Monorail station on the third floor, a separate place from Westlake Station. Then take the Seattle Center Monorail to Seattle Center, and your rail arrival is complete.
