Choose a ticket for 1 day, 24 hours, 48 hours, or 72 hours, then board at any stop and hop off whenever a landmark catches your eye. Your ticket remains valid for unlimited boarding and alighting during its validity period.

How this score is calculated
This score is based on one provider. Viator rates it 3.25 from 55 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 4.9.
