London effectively began in A.D. 43, when Roman forces built the original London Bridge across the River Thames. Since then, the city has grown around the river, which was critical to its development as one of the most important ports in the world. Today, the Thames is as crucial to London as ever, and many of its most iconic sites are located along its banks. Several tour companies offer hop-on, hop-off Thames cruises that allow visitors to enjoy some of London’s loveliest attractions at their own pace. We prefer boat rides because they offer panoramic views, fresh river breezes, no traffic, and often offer onboard food, drinks, and informative tours in several different languages.

We recommend Uber Boat by Thames Clippers, which offers an east and westbound service between 24 different piers along the Thames from as early as 5:30 a.m. to as late as 11:42 p.m., 7 days a week, including holidays. Most other tour companies only travel between four far-apart piers. The one-day hop-on, hop-off option grants unlimited boat rides for a day and costs £22.10 per adult, £11.05 per child, and £44.20 for a family. An extra £11.05 buys concessions on the boat. An Uber Boat ticket will allow riders to enjoy London from the sky as well. For about £10 extra, any ticket comes with a ride along the IFS Cloud Cable Car, which glides 295 feet over breathtaking scenery.
