The Greenwich Foot Tunnel
I’ve always said that any visitor to London should take a Boat trip from Westminster to Greenwich
as it gives a fantastic view of the city from the river and ends up at one of my favourite areas of London. That said, there is an alternative way to get to Greenwich, and that is by way of the automated Docklands Light Railway which travels through Canary Wharf
to Island Gardens, where you can use the foot tunnel to walk underneath the Thames to reach Greenwich on the other side.
