Uber Boat by Thames Clippers (river ride) is a real time commitment — fit it in only if it's a priority.
Allow 40 min–2 hrs.
The genuinely good move on the river isn't a narrated tourist cruise — it's the commuter Uber Boat by Thames Clippers, which passes the same icons for a standard fare. Grab a seat at the back, tap in with contactless, and ride it down to Greenwich for a half-day with a destination at the end.
