I sat with an ice cream near the flower beds of soft grasses and watched the world go by for a while before setting off.
Sir Alexander Binnie's 1217ft foot tunnel was constructed in 1902 so that people living on the south side could get to work in the docks on the north side. It runs 50ft under the Thames and is accessed by a circular staircases around lifts (that's elevators to you guys across the pond!) within distinctive domed shafts.
And it's free.
Considering it was a Saturday and how busy Greenwich was that day (it was tourists a go go!) I'd assumed the tunnel would be rather busy. But as you can see by these pics it was fairly empty. I walked briskly through it, narrowly dodging a lunatic cyclist who either was unable to read all the No Cycling signs or was intent on flaunting the rules.
At the north side I met my friend Jen in Island Gardens and we admired the view as we waited for some other foragers to join us for the walk to Wapping.
The pic below is the view looking back at Greenwich just to the east of Island Gardens at the most southern point of the Isle of Dogs where the Thames Path restarts along the wall at the river's edge. I've just about managed to get all the key Greenwich landmarks into the shot...
L-R: The Old Royal Naval College, University of Greenwich, Naval College Gardens, the National Maritime Museum (hidden by trees), the entrance to the foot tunnel, The Cutty Sark, Greenwich Park and the Royal Observatory and Planetarium
Coming soon... another way to sub-navigate the Thames on foot...
