Seattle Attractions and Tour Tickets
Seattle’s big-name attractions are spread across Pioneer Square, the waterfront, Seattle Center and a few spots well outside downtown. Prices are in US dollars, exclude sales tax, and several change by date, so confirm on each official page before you commit.
Bill Speidel’s Underground Tour
The tour starts at 614 First Ave in Pioneer Square and runs about 75 minutes. It walks the below-street passages left from the rebuilding after the 1889 Great Fire. Tours leave on the hour from 10 a.m. to 6 p.m. daily, with extra half-hour departures in summer sold at the box office. The terrain is described as moderately rugged: stairs, uneven ground and patchy lighting. Tickets can be bought in advance up to two hours before the start, and the tour is closed on Thanksgiving and Christmas. Check the operator’s site for current ticket prices. Beneath the Streets, at 102 Cherry St, is a second operator with tours of about an hour, found mainly on booking sites.
Argosy harbor and locks cruises
The Harbor Cruise lasts one hour, leaves from Pier 55, returns to the same dock and runs daily. The Locks Cruise takes two hours and goes one way, between the waterfront and the Lake Union marina, so plan your trip back by land. Argosy sunset and happy-hour cruises finished for 2026 and come back in May 2027. See Argosy’s cruise comparison for the current line-up. Dress warmly, since wind off Elliott Bay is cold even in summer.
Boeing Future of Flight
The visitor center is at 8415 Paine Field Blvd in Mukilteo. It opens daily from 8:30 a.m. to 5:30 p.m. and closes on 26 November, 24 and 25 December, 31 December and 1 January. The gallery and Sky Deck are $14 for adults and $7 for ages 6 to 15, and children under 6 enter free. The factory tour, which includes general admission, runs about $42 to $46 for adults. Riders must be at least 48 inches (122 cm) tall. There are no cash payments, no food or water and no photos on the tour.
