Transportation from Greenwich to London

You have options. Train or Uber boat. It really just depends what type of experience you are looking for.

Or bus.

Where are the stops in London.

Maybe ir would be better to decide what you want to see first, then figure out how to get there. Here's a good place to start:

Greenwich is approximately 4 miles from the Tower of London. You can reach London by DLR which is Dockyard Light Railway, bus, ferry (various Thames boats), train, or by foot which is 7.6 miles and takes about 3 hours if you don't linger. But this can be your walking tour of the Isle of Dogs, Canary Wharf and Historic Riverside Pubs. Take a Taxi/Uber if you are carrying all your Luggage.

Use tfl.gov.uk to work out how to get from Greenwich to wherever you decide to go

and remember that Greenwich is quite a large place - it has more than one train station, and other transport links.

And there is actually quite a lot to do in and around Greenwich - people staying in London travel out for day trips.

When we visited London a decade ago, we took a ferry out to Greenwich to visit the Royal Observatory, then hopped onto the Tube (subway) at Greenwich Station to get back. That will let you get to whatever part of London you wish to see. (There's also a North Greenwich Station if that's closer for you.) Obviously we could have taken the Tube both ways, or the ferry both ways, no reservation needed.

There is no tube service to Greenwich- it is either the DLR (Docklands Light Railway) to Bank or Tower Gateway, or National Rail to London Cannon Street, or National Rail (Thameslink) to London Bridge, Blackfriars, City Thameslink (for St Paul's Cathedral), Farringdon, Kings Cross/St Pancras and beyond.

The DLR is the most fun, and the most scenic

My bad. I guess we took the train, not the Tube, back to London. Hard to remember the details after all that time, but I know we didn't reserve anything.

I think the main point is that Greenwich is pretty much what most would consider a part of greater London, so the transport options are mostly commuter runs. No reservations needed. You could get to Greenwich Station and take a train into London Bridge Station, get to one of the stops for the DLR, which will connect you with the Underground at several stations, or the Thameslink and Uber boats from Greenwich Pier. Less than 30 minutes will get you many places in London, and hour about anywhere. Taking the DLR and switching to the Underground is probably the most flexible for getting about anywhere, do not even need tickets, just tap in and out.

I took the ferry, nice views, glad I did. If you're a new tourist to London, take the ferry.

The best plan is to take a boat one way and the DLR the other - that gives you the best overall experience. Bear in mind, in case you're not aware, that the DLR is nearly all above ground and generally elevated.

Thank you for your responses. DLR sounds interesting. I live in Boston MA and part of our subway system was above ground many years ago. The sharp turns were always exciting when I was a kid.

To re-create your inner kid if you're lucky you can sit on the front seat of the driverless trains and pretend to drive!

For an additional dimension for the trip into London, you can walk through the tunnel that runs under the Thames from Greenwich to the Isle of Dogs - from there it's a short walk to the DLR station, or you can spend some time exploring the Docklands.

I stayed in Soho in 2024 and went to the National Maritime Museum in Greenwich (near where you'll be docked). The DLR (from the Cutty Stark station) is a good route, as it connects you to the Tube or the Elizabeth Line at Canary Wharf. The 188 bus (towards Tottenham Court Road) also runs towards central London, but does take longer accounting for traffic. No need to reserve tickets for public transport in London, you can tap your credit or debit card or purchase tickets from a machine (your choice). The fares are capped at a certain point, as long as you use the same card to tap in and out with (using 1 card per person).

Thank you for all the great ideas. Another option that I am considering is the hop-on-off Uber Boat and going as far as the Tate and then heading back stopping at various spots along the Thames. We are on a cruise and will only explore London on that day and then Greenwich the next.
Happy traveling!
