A path takes you east of residential streets until you get to an annoyingly busy roundabout (with safe crossings, photo #4), and a big wide road (photo #5) to get you across the Grand Union Canal. The Canal section is nice (photo #6), although you soon leave the main canal to follow the Paddington Branch (photo #7)....

You cross some roads, and then walk in a little curve to line up to cross under the A3113, where you will find concrete blocks blocking the way (photo #2). The walk through the biodiversity side is actually really pretty nice (photo #3), but it does have occasional planes flying over (photo #5)....

Not a fan of walking alongside busy trunk roads, not much to recommend with regards to beauty or interest....

I walked from Stanwell to Harlington with Bert and his troublesome wind. Then Harmondsworth Lane and Sipson Lane, long straight and featureless, unfortunately unavoidable, the airport restricts options....

Strider

Mini railway, ponies, wetland where a River Crane tributary rises, Harlington church (which I wandered around), views from the flyover and old buildings that have seen better days....

North of the M4 is a chance to drop off the A437 onto Bedwell Gardens, and a curvaceous concrete footpath will assist in this, but it is sadly in a neglected state and attracts broken glass and other debris, (photo) so some people may prefer to stay on the main pavement. There is a (mostly) pleasanter alternative, which passes directly the gorgeous old church at Harlington and gives a better idea of the community than the main road. I’ll add it to show the option is there....

At the steep Bulls Bridge you head west towards Hayes but soon turn off and go up a ramped walk way to join the A312 south (see photo), a busy duel carriageway, for a short distance before turning left at the junction and going into the northern section of Cranford Park. You walk south along the flat path into woodlands and then under the M4 to the main part of the park by St Dunstan’s Church and new park facilities that are soon to open, which will include toilets and café. You then join Cranford lane, a quite road, turning left and continue to Harlington....

I walked the Harlington to Hounslow route on a mild February....

After going through the little village of Harmondsworth (photo #2), the walk became actually pleasant (photo #3), even though it started through a graveyard. It was a little muddy going around Saxon Lake (photo #4, #6), but it was quiet and green with a white dusting of fallen blossom (photo #5). After leaving the canal, the walk into Iver is again along a main road (photo #14), as bridge across the canal had collapsed a few years ago....

After crossing the River Crane, the walk finally moved away (photo #5) from a busy road, first along Cranford Park (photo #6, #7) for a little, and then along a lane (with pavement) towards Harlington (photo #8, #9)....

This journey is Harlington to Stanwell Moor, which I walked in two stages. You go through the village of Sipson (222 bus) and at King William pub continue along Harmondsworth Lane to the village of Harmondsworth (U3 and 350 buses). I walked Harmondsworth to Stanwell Moor section on a sunny November day. Accommadation Lane, surprised follow the road and not go through the the park on the right or swan lake by the BA building on the left of the road....

Also, Hayes is a cosmopolitan mix of different food places if you are after refreshments as well as being a transport hub with buses and a train station on the Elizabeth line....

Aamwalk

You then follow the river through woodland, keeping left at each track junction before coming to Cricketfield Road (kissing gate). You then follow the road right (no pavement) until you turn left along Thorney Mill Road (U3 bus nearby) over Fray’s River. I walked around the left hand side of the golf course and followed the white rocks, to the right of the Colne Brook, that take you north through the golf course out to a tarmac lane through a gate (this is different to the route taken by the other reviewer (which is a bit further to the west)....

Aamwalk

I didn’t find the A4 section too annoying, the pavements are wide and road crossings safe, providing you follow the route as drawn and cross where indicated....

I feel I may be being a bit harsh with this review, but having walked it I found the route drawing was a bit rough and ready, which meant having reached the Grand Union canal, I had to guess whether to walk along the canal towpath or the road....

Soon I arrived at the entrance to Cranford Park, and a lovely green corridor, grass and woodland, with a good path, leads to an underpass beneath the M4. Then a little church, St Dunstans, by the Cranford Park visitor centre. Eventually the park runs out onto a small fairly quiet road which leads all the way to Harlington....

For a route that wraps around Heathrow it’s surprisingly quiet, taking full advantage of the Colne Valley between Stanwell Moor and Harmondsworth; and sticking with a fairly quiet road between Harmondsworth and Harlington. There is also a very tight access point to the Biodiversity site north of Stanwell Moor. The route goes straight across the site (this is the main difference between this option and Stahar One, as this is where the planes can get rowdy and the route benefits from directness at this point). The only exit point south from the biodiversity site is through an underpass (another spur off the M25), which is almost entirely blocked, with just a tiny space left for access (photo). After that it was straight along the river to Stanwell Moor and the pub at the end point...

Totally recommend - one star off for a couple of unavoidable busy road sections, otherwise everything a Slow Way should be. There’s a short stretch of busy road before plunging back into more green along a golf course. Under the M25 - celebrate leaving London - then up a steep slope to the road, turn left and walk north to Iver. At this point if you want the railway station don’t walk into Iver, turn right and walk south instead....

It’s not only a major road, it’s also under the final Heathrow approach, the planes are loud here. The route doesn’t go into the park, it would be possible to include it a little, which would break up the pavement pounding. I turned right into Park Lane, which later becomes Cranford Lane (another one), and leads all the way to the end point! Park Lane follows the southern boundary of Cranford Park. I did reccy options for using Cranford Park, but I don’t think it’s possible to bypass this part of the route (other than by rerouting alongside the A4). Another thing about this part of the route: there is lots of frustratingly inaccessible green space along Cranford Lane, the skylarks were loving life, and generally I felt the landowner could be a bit more generous about allowing public access to these spaces....
