Full description
Explore London at your own pace with a combined hop-on and hop-off river cruise, and entrance to the Royal Observatory in Greenwich Park. Admire the city's most famous monuments, including St. Paul’s Cathedral, the Houses of Parliament, and Tate Modern.

You can board the boat at Westminster Pier, London Eye Pier, Tower Pier, or Greenwich Pier. Hop on and off at leisure as you sail past sights such as City Hall, the Tower of London, the O2 Arena, and Cutty Sark. The all-weather boat is wheelchair-accessible, and most vessels include an open-air deck for those once-in-a-lifetime photo opportunities. All boats have toilets, bars to buy refreshments (own expense), confectionery, snacks, and an upper viewing deck for photo opportunities. Alight at your leisure at Greenwich Pier and stroll up to the Greenwich Royal Observatory for sweeping views over Greenwich Park and the Thames River.

Then, explore the past, present, and future wonders of astronomy at the Royal Observatory, Greenwich. Learn how great scientists mapped the seas and stars, and stand astride 2 hemispheres at the Greenwich Mean Time Meridian Line. Touch a 4.5-billion-year-old meteorite, watch how the universe was formed, guide a space mission, or unravel the mysteries of the cosmos.
