Not much else to see on the South side maybe, but on the North side of
the river is Thames Barrier Park, a really beautiful place and a fine
view of the Thames Barrier. Easy to get to - just take the DLR to
Pontoon Dock. Everyone I have taken there has said its one of the best
places in London. You can also walk back to Custom House DLR via the
bridge over Royal Victoria Dock which has some stunning views over the
Docklands area.
