In the latest of my Chiltern Rivers Cycle Rides I explored the River Ash at the Southern end of the Colne Valley Regional Park. The Ash splits off from the River Colne next to the A30 Staines bypass North of the town and follows a South-Easterly direction to meet the Thames at Walton-on-Thames. Much of the route is hidden from public access so a cycle or walking trip of the Ash is one for the completists only. That definitely describes me so I had to do it. The reward for tackling it is the return route to Staines via the Thames Path.

The best place to start (if you’re driving there) is some free parking space on Moor Lane opposite the path to Staines Moor. Following this path you’ll pass over the Wraysbury River, the Staines Rivers Aqueduct and the rail line. You’ll need to use the A30 bridge to cross over the River Colne where you’ll find the point where the Ash splits on the Eastern bank. From here you can follow the Ash on a footpath for ~300 into a housing estate. For the next 4 km you won’t see the river as it keeps close to the A308 and cycling options zig-zag through residential areas of North Staines. You could cycle on the A308 to stay closer to the river and shave off some distance, but it’s a very busy road and you won’t see the river anyway.

The Ash, the A308 and the cycle route all come together at the Fordbridge Roundabout. Here the Ash takes a sharp turn right to the South and curves round the Queen Mary Reservoir through Laleham. The best cycle option is to follow the B377 Ashford Road then the B376 Shepperton Road. At Shepperton you have the choice of continuing along the B376 or taking a meandering route through Littleton, Shepperton and Upper Haliford to stay closer to the river.

The confluence with the Thames is tucked away behind a small island. You can get there by taking a private residential road called The Creek off Fordingbridge Road. A rickety wooden bridge stands over the confluence marking the end of the Ash part of the trip.

To return to Staines, go back to Fordingbridge Road and follow it West to the A244 and follow that onto Walton Bridge. Cross over the bridge and take the Thames Path back to Staines. I added an extra 1 km to the trip by taking a diversion along the perimeter paths of Desborough Island. One of the highlights of the trip is taking the small Hammertons ferry to the North side of the Thames. Check that it’s running before you go though as you’ll add a few extra km to the trip to find the nearest alternative crossing by bridge.

When you arrive back at Staines take the B376 heading North away from Staines Bridge. Take a right onto Moor Lane and continue for ~500m back to the parking spot.
