About this tour

See London from its busy streets and from above on a six-hour London walking tour and O2 climb. With a local guide, explore Westminster and the Southbank, taking in more than 30 notable sights and hearing stories about the city’s history, culture, and legends.

The walk begins near Green Park and heads toward Westminster, with views of Buckingham Palace, Downing Street, Westminster Abbey, Big Ben, Parliament Square, and the Houses of Parliament. On select days, you may also see the Changing of the Guard; its schedule is set by the British Army and can change without notice. Continue to the London Bridge area for sights including Shakespeare’s Globe Theatre, The Shard, HMS Belfast, Tower Bridge, and London Bridge. After the guided walk, use your included entry ticket to climb over the O2 Arena. Your guide does not join you for the climb.

How this score is calculated

This score is based on one provider. Viator rates it 4.81 from 27 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 7.1.
