Visit Greenwich, the historical home of the observatory and origin of Greenwich Mean Time. From Tower Pier in central London, take a 30-minute boat cruise along the Thames, reaching Greenwich just in time for a tasty pub lunch (included). Then head off to explore this characteristic little town dominated by great examples of Georgian and Victorian architecture. Walk to Greenwich Park where you'll admire a breath-taking view of London's skyline. At the top of the park are situated the Royal Observatory and the world-famous Greenwich Meridian, the point where East meets West!
