Denham (Buckinghamshire). Denham Deep Lock is particularly impressive especially when you stand beside the huge lock gates - this is the deepest lock on the Grand Union Canal - changing the water level by 11 feet 1 inch.

Grand Union Canal - Bridge 192
Cowley Peachey Junction is where the five mile long Slough Canal Arm leaves the Grand Union Canal - the Slough Arm (perhaps obvously) ends at Slough and has no watery connections for narrowboats thereafter. However shortly where after the Slough Arm leaves the Grand Union you reach the junction with the Paddington Arm which starts it's journey from the Grand Union at Bull's Bridge and ends up by Paddington Station in West London. The Paddington Arm does offer cyclists, walkers and of course narrowboats options to continue elsewhere as there is a connection with the Regents Canal which in turn gives access to two river navigations i.e. the Lee Navigation and the Stort Navigation.

One of the best parts of this final run by the Grand Union Canal into London and the Thames are the 6 locks that comprise the Hanwell Locks Flight which are built through really nice countryside. The towpath is generally in good condition for walkers and cyclists however you should be aware that - especially between Bridges 192 and 196 - some idiots are using the towpath to race up and down on small and of course un-licenced/un-insured motorbikes. Whilst in this area from the towpath if you look between the hedgerow you can easily spot the huge Sikh Temple at Southall with it's dome glinting in the sunshine (photo on the above photo row).

Three Bridges (also known as Windmill Bridge). This particularly interesting bridge(s) was built in Victorian times (1856) by Isambard Kingdom Brunel. Windmill Lane - supported by huge girders - crosses over the Grand Union Canal and the canal in turn goes over a single track railway line. The canal is encased in an 8 foot deep cast iron trough and other parts of the bridge have really nice brick arches.
Hanwell's six locks drop the Grand Union Canal by around 53 feet - the whole area around Hanwell lock flight is really pleasant to walk or cycle through. As you pass Hanwell Lock (Lock no.92) you then walk for ages alongside a really nice wall on the left of the towpath - bordering the extensive grounds of what was once the County Asylum (known as Hanwell Asylum) and what is now Ealing Hospital. There is a bricked up entrance into the grounds via which at one time canal boats would deliver coal for the Asylum's boilers and take away vegetables, fruit and animal products produced in the asylum's huge market gardens. Many years ago when the Grand Union Canal was used commercially the boatmen called the dock Asylum Dock and the lock itself was known as Asylum Lock.

Muddy at Low Tide around The Thames - Brentford

The River Thames - Kew on the opposite bank
Towards the end of the Grand Union Canal Main Line starting from Brentford Gauging Locks and on down to the River Thames the canal is affected by tides and therefore boaters should consider the amount of headroom during a rising tide.
Thames Lock itself has a permanent Lock Keeper and the lock can only be used at certain times - these times do change from time to time but as of Mid September 2011
(but do check this for any change) the Lock was available either side of high tide 0800-1800 between 1st April and 30th of September and - subject to tide and pre-booking - 0800-1600 between 1st October and 31st March. The Grand Union Canal ends
it's long journey from Birmingham at Thames Locks - the remaining few hundred yards making the connection down to the Thames is on the River Brent.

We have picked out a few Books about England - concerning the waterways of England. The Nicholsons Waterways Guides are
a "must take" for anyone going on a Canal Barge or Narrowboat holiday (as well as anyone visiting the canals) as they are packed with really useful information.
(The relevant Nicholson Guide covering The Grand Union Canal is BOOK 1.)
If the development and history of our English and British Canals is of particular interest consider looking at the Anatomy of Canals series which are really good reading!.
