Seattle Tours: Underground, Boats and Boeing
Seattle’s ticketed attractions suit different travelers, so this page is organized by the question most visitors ask. Prices are US dollars before sales tax, and any figure marked “about” or “from” should be checked on the official page.
Which tour is best for history?
Bill Speidel’s Underground Tour at 614 First Ave in Pioneer Square walks through passages beneath the streets for about 75 minutes. Departures are on the hour from 10 a.m. to 6 p.m. each day, and it closes on Thanksgiving and Christmas. The route is moderately rugged, with stairs and uneven floors, so skip it if mobility is a concern. Current fares are on the operator’s website , and a second company, Beneath the Streets at 102 Cherry St, offers a roughly one-hour version.
Which tour is best on the water?
Argosy has two cruises worth knowing. The Harbor Cruise is one hour, departs from Pier 55 and comes back to the same pier. The Locks Cruise is a two-hour trip that ends at Lake Union, so it does not return you to the waterfront. Evening cruises are paused until May 2027. Fares are on Argosy’s site . Wear a windproof layer, because Elliott Bay breezes are cold.
Which tour is best for aircraft fans?
Two places, two experiences. The Boeing Future of Flight in Mukilteo (8415 Paine Field Blvd) offers a gallery and Sky Deck for $14 and a factory tour of roughly $42 to $46 that includes the gallery. Children must be at least 48 inches (122 cm) tall for the factory, and there are no photos, no food and no cash on site. Arrive 30 minutes early, since late arrivals lose their booking. The Future of Flight page shows the schedule.
The Museum of Flight (9404 East Marginal Way S) is a different kind of visit, with aircraft to explore at your own pace. Adults pay $29, seniors $25 and ages 5 to 17 $21. See the museum’s visit page .
Which attraction suits a rainy afternoon?
The Seattle Aquarium and MoPOP both open daily. The aquarium runs 9:30 a.m. to 6 p.m. and one ticket covers all three of its parts: Pier 59, Pier 60 and the Ocean Pavilion. One exhibit, the Puget Sound Fish habitat, is closed from 19 October 2026. MoPOP opens 10 a.m. to 5 p.m. at Seattle Center, uses date-based pricing and gives Washington residents 15 percent off with ID.
Is a pass worth buying?
Seattle CityPASS is $139 for adults and $119 for children 5 to 12. It includes the Space Needle and the Seattle Aquarium, plus three choices from Chihuly Garden and Glass, an Argosy Harbor Cruise, MoPOP, Woodland Park Zoo and Pacific Science Center. It lasts 9 days from first use and every venue requires a reservation, so book time slots as soon as you buy. The CityPASS page lists the current rules.
A note on the Space Needle
The Space Needle at 400 Broad St uses timed entry and general admission of $35 to $55. Do not plan around a restaurant at the top, because the tower has a glass floor and a walk-up bar instead.
