This cleverly conceived tour of Seattle's historic ‘underground’ – the part of the city that got buried by landfill in the 1890s – benefits from its guides, who are excellent, using wit and animation to relate Seattle's unusual early history.

The tour starts at Doc Maynard’s Public House with a lighthearted preamble and progresses through a series of subterranean walkways whose shabbiness adds to their authenticity. It is massively popular, especially in prime tourist season, so book ahead via the official website where possible.
