Denham represents perhaps the last outpost of Shire England to the west of London before the capital's sprawl takes over. Appropriately, this circular walk describes a ring around the intersection of the M40 with the M25, but don't let that put you off, as the route provides an excellent way to enjoy a protected area, with remnants of market gardens and nurseries providing a reminder of how the villages around here once supplied fresh fruit and flowers to the capital. Its waterways also provided a means for city dwellers to reconnect with nature, and the walk links with both the River Colne and the Grand Union Canal in its early stages. Allow a good two hours to complete the walk. There's a useful Visitors Centre at the start providing refreshments as well as a canalside pub about a third of the way in. Although the path is good most of the way, some sections of fields can get muddy, so boots are recommended. Some of the latter parts of the route can be heavily overgrown and can even become impassible in later summer. There are a number of stiles in the latter part of the walk. Whilst most of the major road crossings are via underpasses or bridges, you will need to cross the A40 at one point (you will be aided by a central island, but no traffic lights or other traffic control).

Definitely not a winter walk. Trail was overgrown to the point of inaccessibility in some areas. Despite no rain for a few days some paths resembled a creek/bog with no alternative route other than turning back or wading on. Occasional parts through a group of farm buildings where track is unclear and it feels like trespassing. Road noise in incredibly obvious, but shouldnt be unexpected. Trash EVERYWHERE, makes you rather disappointed really.

It’s a nice walk along the canal, but between 4 & 5 it’s overgrown & we had to cut through a farm but got back on track easily. It was 30c when we did this so maybe a cooler day is better. Nice cafe & river spot at the start/end.

Unfortunately the first not very nice walk from this App. Very noisy due to proximity to the M40, busy roads and roundabout to cross and large parts are littered with fly tipping rubbish
