End of the Line 3: Uxbridge to Rickmansworth
It’s easy to forget the dominant role water has played in forming the geography of the Thames Valley; this walk brings that role to the fore, highlighting the rivers, canals and wetlands of the capital. From Uxbridge station the route follows the London Loop/Colne Valley Trail, initially along the towpath of the Grand Union Canal. The Grand Junction Canal, as it was first named, was dug between 1793 and 1805 to connect the Midlands to London and, until the rise of rail and road, it carried huge volumes of goods and from the capital.
Once you pass under the M40 the land opens out, wet and expansive on either side, with a series nature reserves (most with bird hides to sit and view the large numbers of ducks and wildfowl that use the lakes) flanking the canal, and stretches of carr, alder and willow dominated wetland . It’s best to get on to the paths that run along the lakes, rather than following the towpath all the way, to get the best views of birds and water – the fortunate will be rewarded with the electric blue flash of a kingfisher.
A turn up the Hillingdon Trail avoids the valley bottom section of the Colne Valley Trail that goes past a sewage works (stay with the CVT though if you want to see staggering numbers of gulls), and opens up to views over the valley; a landscape formed by water.
Dropping back down to the CVT takes you to Stocker’s Lake, a drowned gravel pit, now home to the largest heronry in Hertfordshire, and just beyond the welcome café looking over Bury Lake. A good place to stop and reflect, with something liquid, on how water has formed our geography and our history, before walking the final short distance to Rickmansworth tube station.
Walk here: Head straight from the station up Bakers Road, then follow the High Street L until it crosses the Grand Union Canal. Head north along the canal, following the London Loop/Colne Valley Trail signs, all the way to where the Hillingdon Trail heads uphill right at the Coy Carp pub. Take the Hillingdon Trail uphill; where it splits, follow the L path to rejoin London Loop/Colne Valley Trail past sewage plant. Continue to Rickmansworth.
