Underground Tour

A scheduled, 75-minute walking tour beneath Pioneer Square's rebuilt street level.

The useful answer

Should this fit your day?

Best for: Visitors who prefer local history and storytelling to a conventional observation deck or museum.
Time to protect: Protect about two hours around the 75-minute tour for check-in, finding the entrance, and returning to transportation.
Cruise-day fit: Pioneer Square can fit a longer Pier 66 day, but a fixed tour time is risky close to embarkation. Pier 91 requires an additional road leg.
From the terminals: It is south of Pier 66 and well south of Pier 91. Do not assume the waterfront is one continuous cruise-terminal walking zone.
Before a flight: A scheduled tour reduces flexibility. Use it only when the airport departure buffer remains intact after the stated finish time.
