No trip to London is complete without a Thames River cruise. Get the lay of the land on the first day of your trip and sail through Central London to experience a unique view of the London skyline. Different Thames cruises offer both one-way and roundtrip options on a variety of routes with commentary from an experienced skipper, with sights including the Houses of Parliament, Big Ben, St Paul's Cathedral, Shakespeare's Globe Theatre, HMS Belfast, Westminster Abbey, the Tower of London, and Tower Bridge. If you fancy capping off your stay in London and want to sum up your favorite sights over a pint with dinner (and more drinks), there's an option for that, too. Looking for more action than a leisurely Thames River cruise? Opt for a speedboat tour for an exciting, one-of-a-kind way to experience the lively city of London. Or, use the Thames River cruise as a main mode of transportation as you hop-on and hop-off all about this classic European city.

Cutty Sark was the last and fastest tea clippers to be built in Britain, and you can learn all about its journeys across the oceans on board the ship itself. It is now permanently docked in London's leafy Greenwich area. Cutty Sark, an award-winning visitor attraction, is easy to reach via the DLR – it has its very own stop!
