Trace London’s espionage stories on a private walk from Somerset House to sights near MI6, guided by clues from the public record.

About this tour

London’s spy story is built from fragments: declassified files, memoirs, and the occasional leak. On this private walking tour, follow those clues through a city where the most intriguing places can look entirely ordinary. Your guide shares what is known about the people and organizations working behind the scenes, separating public record from the mysteries that remain.

Begin in the central courtyard of Somerset House and explore discreet and infamous sights connected to espionage. The walk ends near MI6, tracing a route through the capital’s secretive side while offering context for curious newcomers and dedicated spy enthusiasts alike. Along the way, hear how intelligence work stays out of view and why London has become such a compelling setting for stories of spies.

This London Spies and Spying Walking Tour cannot reveal every secret, but it brings the known history into focus. Meet your guide at Somerset House and discover a different side of the city on foot.

How this score is calculated

This score is based on one provider. Viator rates it 5.00 from 7 reviews. We place that rating among all Viator ratings and weight it by its review count. If the tour is found on another provider later, both ratings are combined.

How the score works and rating distribution in London
  • Each provider rating is turned into a percentile: the share of that provider's ratings it beats, weighted by review counts.
  • Listings on different providers are combined in proportion to their review counts.
  • Tours with few reviews are pulled toward the average until more reviews come in, so a handful of perfect reviews can't top the list.
  • The result is shown from 0 to 10: this tour scores 7.5. Top 26% in London means it ranks in the top 26% of tours in London by this score.
