The Regent's Canal dates from 1820 and is part of the Grand Union Canal, which links London to various other canal systems across Britain. Previously the Grand Union Canal had reached as far as Paddington and so the Regent's Canal was added in order to extend it all the way to Limehouse in the London Docklands
Also known as the North Metropolitan Canal, the Regent's Canal runs from Little Venice in the west, past Regents Park and the London Zoo to [Camden Lock]?, where the famous Camden Market is held, through a tunnel under Islington, onwards past pretty Victoria Park and its junction with the Hertford Union Canal, alongside Mile End Park and on all the way to the Docklands.
Along the way there are numerous waterside pubs and restaurants, which make up a very pretty route right through the centre of London. You can also go on various narrowboat cruises along the canal, which is a lovely way to see a hidden part of London.
On New Wharf Road, near King's Cross Station, there is a Canal Museum where you can find out more about London's canals.
The Regent's Canal is an excellent cycling route across East London. Cyclists and pedestrians usually co-exist fairly well, but you should ting your bell twice as you come up behind people. Read London's Towpath Code of Conduct for more information.
