A truly unique Seattle experience! Go underground on our guided tours of historic Pioneer Square and it’s below-the-sidewalk passageways. Seasoned guides, small groups and great reviews set us apart from our competitors. We operate 7 days a week, rain or shine. Group rates and private tours also available. Hear about, see, and touch 1890’s Seattle while touring underground spaces that have never before been part of public tours.
