The intention is to have a pub lunch on this walk so packed lunches should not be required. Car shares, however, will be required.

Drive to The Chimes car park, Chippendale Waye, Uxbridge, UB8 1TP - https://maps.app.goo.gl/RM8gQS1YUHu6ZaHV7
arriving at 10:00 am latest.  This car park costs £6.75 for up to 6 hours or £9.35 for up to 8 hours.  6 hours is a bit marginal for this walk so it’s best to bite the bullet and pay for 8 hours.

Exit the car park by turning left on to Chippendale Waye / York Road and walk to Bus Stop W (https://maps.app.goo.gl/Ub5tjGz7bzQmFXHV9)  in York Road.
Catch 725 bus at 10:22 am to Rickmansworth Station, Stop C, 
(https://maps.app.goo.gl/gzRhjYgWGGhWw6zDA) arriving at 10:56.  Note that this service only runs hourly so it’s essential to catch the 10:22 bus.

From the bus stop in Rickmansworth, walk down Station Road to Rickmansworth High Street.
Stop on High Street for coffee/tea/toilets at Costa, Starbucks, Caffe Nero or Wetherspoons.
Leave coffee stop and start walk at around 11:30 am, continuing along the Hight Street before turning right down Church Street to the Batchworth roundabout.

Exit the roundabout, still on Church Street.  After walking across the River Colne, cross Church Street and go down some steps to a path between the River Colne and The Grand Union Canal.  Follow this path for several miles along the Grand Union Canal which more or less follows the route of the River Colne.

At Moorhall Road, at just under 5 miles, go into The River Garden pub for lunch at around 13:30.
This pub has extensive menus which can be viewed at https://www.therivergardenpub.com/menus.

Leave the River Garden at around 14:30 and walk a further 3.2 miles back to The Chimes Car Park in Uxbridge, arriving at around 16:00.

There are several café and pub options in Uxbridge for further refreshments and toilets before returning to the cars.
