Plan your visit to Underground Tour in Seattle: what to see, practical tips, how to get there and nearby highlights.

Underground Tour

Beneath the bustling streets of Seattle lies a hidden world waiting to be explored. Bill Speidel's Underground Tour offers a fascinating, humorous, and sometimes spooky journey into the city's buried past.

What to expect

This guided walking tour takes you through the remarkably preserved storefronts and sidewalks of Seattle's original Skid Road, now several feet below the current street level. Descend into dimly lit underground passages, where costumed guides recount tales of the Great Seattle Fire of 1889 and the subsequent rebuilding effort that literally elevated the city. You'll see remnants of old businesses, including a former saloon and a doctor's office, and learn about the daily lives of Seattleites in the late 19th century. The tour is approximately 75 minutes long and involves a fair amount of walking, with some uneven surfaces and stairs.

History & significance

Seattle's original downtown was built on pilings over tidelands. After the devastating Great Seattle Fire in 1889 destroyed most of the wooden structures, city leaders decided to rebuild using concrete and brick. To improve sanitation and drainage, and to protect against future floods, the streets were raised by an average of 10 to 26 feet. This meant the original ground floor of many buildings became basements, and new ground floors were constructed above them. These buried levels, largely forgotten for decades, are now accessible through the Underground Tour, providing an unparalleled glimpse into the city's formative years and its resilience in the face of disaster. The tour highlights the ingenious engineering and the social dynamics that shaped early Seattle.

Practical tips

Book tickets in advance, especially during peak season, as tours often sell out. The underground environment can be cooler than the surface, so bring a light jacket. Comfortable walking shoes are essential. Tours run rain or shine, so be prepared for Seattle's unpredictable weather. Restrooms are available at the starting point but not during the tour itself. Photography is generally allowed, but be mindful of your surroundings and the tour guide's instructions. The tour is not fully wheelchair accessible due to stairs and narrow passages.

Getting there

The tour departs from the Seattle Underground Tour Welcome Center, located at 608 First Avenue in Pioneer Square. Pioneer Square is easily accessible by public transportation, including numerous bus lines. If driving, several parking garages are available in the vicinity, though parking can be expensive.
