This review is of the Greenwich Cruise Pier where our Viking ship docked while in London. It is surprisingly hard to find information about this location, so I'm writing this to help the next TripAdvisor traveler.
Our ship anchored in the middle of the Thames, right between Canary Wharf and Greenwich. To get to shore, Uber boats (similar to a Viking tender) shuttled passengers to/from the ship and the Pier. The ride is very short - maybe 4 minutes, but the process to get on the Uber boat, wait, and then drive made it a 20-30 minute all-in process. The Pier is right at the Cutty Sark if you are looking for a map reference point.
So Greenwich is very easy to access if your cruise ship stops here. Canary Wharf, by contrast, is much more difficult to access if you are thinking of going to a restaurant on that side of the river.
Cruise ships that stop at the Greenwich Cruise Pier provide a huge advantage to travelers going to London versus ships that go to Southampton and call it "London" even though it's quite a distance away.
