1. Seattle: Underground Walking Tour
Take this 1-hour journey back in time and allow your guide to take you below the streets of Seattle. Explore over four city blocks of historic Pioneer Square and wander through three underground passageways originally constructed in the 1890's. Learn the historical details leading to the birth of Seattle as it is knows today, and the decision to raise the city streets out of the swampy grounds. See where retaining walls were added alongside the streets and filled to make new roads several feet above where they originally stood.
