| The entrance to the Greenwich foot tunnel at Greenwich. |
Of the roughly 40 tunnels beneath the River Thames, the majority of which carry utilities, railway lines and motor vehicles, only three allow pedestrians to use them: The Greenwich Foot tunnel, the Woolwich Foot tunnel and the Rotherhithe tunnel, although the latter is not advisable, unless you want to look like a chimney sweep and breathe in noxious fumes.
The Greenwich foot tunnel, which I have traversed on numerous occasions, is the oldest pedestrian foot tunnel in London, linking Greenwich with Island Gardens on the Isle of Dogs.
The south entrance is located in front of the Cutty Sark, while the north entrance is situated in Island Gardens.
You have the option of descending the stairs or wait for the lift to be free. I always take the stairs, which spiral down to the white-tiled tunnel.
Running in a straight line, it takes roughly 8 minutes to traverse.

The northern end has some thick concrete and steel lining, which covers bomb damage from World War II, that does narrow the interior of the tunnel for a short distance.
