Half an hour of grass and old stone, a few minutes from the Bath Road

Parkland that outlived its house

Cranford Park was once the grounds of Cranford House, the country seat of the Berkeley family for around three centuries. The house itself was demolished soon after the Second World War, and the M4 was later laid along the northern edge of the old estate. What survived is the part worth walking: the stable block, the parish church, and open grass and trees running down to the River Crane.

It lies just east of Harlington, between the village and the river. For a guest staying at one of the big hotels where the Bath Road meets Harlington, it is the nearest piece of genuinely old England, and almost nobody in those hotels knows it is there.

Getting there from the hotel row

From the eastern hotels it is a short taxi ride, and the simplest instruction for a driver is the church at Cranford Park. On foot it is possible, twenty to thirty minutes along main roads, but the walk there is the least attractive part of the outing, and a car is worth taking both ways when the time is short.

Go in daylight. The park is not lit, the paths away from the buildings are grass and earth, and after rain the low ground by the river is soft. Flat shoes are the only equipment needed, and it is worth mentioning them to whoever is coming with you before she sets off from town.

Book the return car at the same time as the outward one. Taxis do not cruise past the edge of a park in west Middlesex looking for passengers, and ten minutes spent waiting at a gate in the dusk undoes most of the good the half hour did. A driver who waits, or one booked for a set time, is the simple answer.

The stable block and the church

The stable block is the grandest thing left of the estate, a long range of old brick that gives a sense of the size of the house it once served. Standing in front of it, with the traffic out of sight behind the trees, it is hard to believe the terminals are a few minutes' drive away.

St Dunstan's church stands close by, small and old, with a medieval tower and a churchyard under the trees. Inside are monuments to the families who owned the estate, and the seventeenth century churchman and historian Thomas Fuller, who was rector here late in his life, is buried in the chancel. Whether or not the door is open on the day, the churchyard alone is worth ten minutes of a long stay guest's evening.

Down to the river meadows

From the buildings the paths run east and down to the Crane, a small river with rough banks and meadows that are mown only now and then. A loop down to the water, along the bank and back up past the church is a gentle half hour, which is exactly the length of walk a tired body can manage and a restless mind needs.

The aircraft do not vanish. When the airport is landing towards the west they pass low on their final descent a short way to the south, lower than seems quite reasonable. Most long stay guests find that watching them from a meadow, rather than through a sealed hotel window, changes the way the whole week feels.

Why it matters by the fourth night

A single night at the airport needs nothing but a room. By the fourth or fifth night of a posting, the recycled air of the hotel, the same bar and the same breakfast have a cumulative effect, and the evening starts to feel like an extension of the working day. Half an hour of grass, old stone and moving water breaks that more reliably than a better restaurant.

It also makes for a different kind of conversation. People talk more easily walking side by side than sitting across a table, and a guest who has spent the week explaining a project finds he says something else entirely on the path by the river. For contractors staying in Hayes and along the row, this is the closest place where that happens. Hounslow has green spaces of its own further east, but Cranford is the one on the doorstep.

Fitting the walk into an evening

The girlfriend experience as this desk arranges it is conversation first and no performance, and a walk suits it better than almost anything else on offer out here. In summer, start at six and there is ample light for the loop, then back to the hotel for dinner and the rest of the evening. In deep winter the light has gone by half past four, and the walk only works as a weekend afternoon.

The walk counts inside the booked time, and so does the short ride to the park. Three hours at £700 holds a half hour loop comfortably. For the host left behind after a day of meetings, described in meeting rooms for a fly in, fly out day, it is the best way there is to close the working part of the day before the evening begins.

Who likes the walk

Three names suit it particularly well, two of them from the ten on the curvaceous list. Milena likes an evening with an outdoor beginning and will gladly walk before the light goes. Bianka is a regular on the Bath Road, warm and quick to laugh, the kind of company that turns a muddy path into a joke rather than a complaint. Tiffany knows Harlington's lane and churchyard well and likes to start an evening with something small and local. Every figure is printed on rates, and the way a booking is confirmed is on booking.

If none of those three is free on the night, mention the walk in your opening message so that the desk can put forward someone who genuinely enjoys one rather than someone who will merely tolerate it.
