From Camden in London, west along Regent’s Canal path to Little Venice at Maida Vale. The path soon leads to Regent’s Park, where the canal cuts trough the zoo, and the back gardens of some stately homes side by side along its banks. Then there’s a tunnel, so one has to re enter London streets a while, before the busy but tranquil Lisson Grove moorings and Little Venice itself. After an unusual request, I walked a little way along the Grand Union Canal, to Paddington Station.
