About this tour

See London’s celebrated landmarks on foot, then trade the city streets for a climb above the O2 arena. This six-hour experience pairs a three-hour guided Westminster walk with admission to Up at the O2, bringing classic sights and a memorable rooftop-style adventure together in one day.

Meet your local guide near Green Park and explore the heart of Westminster in a small group of 10–15 guests. Along the way, take in Buckingham Palace, Downing Street, Westminster Abbey, Big Ben, Parliament Square, and the London Eye, among more than 20 notable sights. On select days, you may also see the Changing of the Guard. After the walk, your guide provides your O2 tickets and directions to the arena. There, expert staff help you put on a safety harness before you climb to the summit and enjoy views across London.

With a local guide, a compact group, and two very different ways to experience the city, this London Westminster walking tour and Up at the O2 climb makes a rewarding day out. Book your place and see the capital from street level and above.

How this score is calculated

This tour has no TourTruth score yet: Viator doesn't show a usable rating for it. It gets a score as soon as a provider lists one.

How the score works
  • 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. Tours without a usable provider rating are not scored.
