Unearth Hidden History: Exclusive Underground Journey
Go underground on a 1-hour walking history tour through Seattle's original neighborhood. Our experienced guides lead small groups above, and beneath, Pioneer Square to the street level that existed in the 1890s. Explore underground pathways that were built more than 120 years ago, learning details on early Seattle history, why these spaces were built, and how they have been used (and misused) over the years. Marvel at how this former tidal flat has since transformed into one of the 20 largest cities in the United States.

Very informative. I heard about this but seeing the remains is more telling. Bring good walking shoes.

Learned a lot of interesting facts. Even found some i had to do more research on because I wanted to know more. It's always good to learn some details and history about the place you are visiting.

Great experience!! Our tour guide was Dave and he explained everything so thoroughly, we couldn’t even think of extra questions to ask him! Lots of cool history to learn and unusual underground tunnels to see!! Loved it!

It was super engaging and adventurous. Cater, the guide, sounds knowledgeable and passionate. Learned tons about the city and how history should be appreciated.

It was a super awesome tour. Carter was very informative, and since we were all adults she gave a more detailed history about the prostitutes. SUPER enjoyable, 20/10, will heavily recommend Carter to anyone who visits Seattle!

Jennifer was truly an amazing tour guide. She is very knowledgable about all things Pioneer Square/Seattle. It was a great tour, I would highly recommend. We left the tour still thinking about the history of Seattle days afterwards!
