Things to do
Seattle sits between Puget Sound and Lake Washington on hills that open onto Mount Rainier on clear days. The centre is compact but steep, so the light rail and buses save energy on the climbs between the waterfront and Capitol Hill.
Pike Place Market
Reach Pike Place Market at opening, when fishmongers lay out the catch and bakeries have not yet built a queue. Walk down to the waterfront, pass the Ferris wheel and continue to Pioneer Square.
Seattle Center
Go up the Space Needle, then look at the Chihuly glass sculptures in the garden beside it. From there cross the park to MoPOP and ride the monorail back into the centre.
The Bainbridge ferry
The ferry from Pier 52 crosses to Bainbridge Island in about half an hour. Walk from the landing along the main street to the bakeries and wine rooms, and leave the return crossing for the evening.
Where to stay
Capitol Hill
Capitol Hill suits bars, bookshops and coffee rooms away from the tourist centre. Pike Place Market is within walking distance, but the slopes are steep and the streets stay loud at night.
Ballard
Ballard is an old fishing district with breweries, a market and workshops. It offers calm rooms away from downtown, though museums are half an hour away by bus. The locks are worth a separate stop.
Pioneer Square
Pioneer Square is built of nineteenth-century brick and stands next to the stadiums. The location works for the station and the waterfront, but few cafés stay open in the evening.
Getting to and around Seattle
Seattle-Tacoma airport connects to the centre on the Link light rail, about forty minutes to Westlake station. Buses and the same Link line cover the city, and a short monorail links downtown with Seattle Center. Streets climb over hills, so use transit for longer hops and walk the downtown blocks.
Three days in Seattle
Pike Place and the waterfront
Start at Pike Place Market, drop to the water and walk past the Ferris wheel to Pioneer Square. Return downtown in the afternoon and visit the art museum. The museum has rooms of modern art.
Seattle Center and Queen Anne
Give the morning to the Space Needle and the Chihuly garden, then look through MoPOP. In the evening climb Queen Anne to Kerry Park for the skyline and Mount Rainier.
Ballard and the ferry
Ride to Ballard, walk the market and breweries, then take the ferry to Bainbridge. Hire a bike on the island to reach the beach, and come back for dinner and a stroll along the Elliott Bay waterfront.
