Stage 41 – A Spring of Pure Water

One of the fantastic things about Scotland is you can step outside and you’re not far from a mountain stream of clear, clean water (Yes mum, I’ve checked there’s no dead sheep at the top!)

Who would’ve thought the same was possible in London?

But a train to Bromley then a bus to Keston will bring you to the source of the river Ravensbourne, a pure crystal stream rising from the chalk acquifer below, in a setting of some geographical and historical interest.

For starters there is an iron age encampment – which is to say the trace of the deep ditches dug to encircle a camp and protect those within; the place is now called Caesar’s Camp because the roman soldiers either took the site or found it abandoned, an ideal place to pitch tent on their march from the coast to the north: high up, already fortified, surrounded by game and supplied by fresh water; no surprise they wanted to come back to this country with a bigger force.

It stands on what is now the property of Holwood House, one time residence of William Pitt the Younger, so called because he became Prime Minister at age 24, which is like looking at my son and saying you’ll be Prime Minister in four years’ time

It was here that Wilberforce came to the course of action that arose from his conviction that all people are created equal.

And just down the road is Charles Darwin’s house, from where he was able to connect the flora and fauna of this area with all that he had encountered on his travels, and through the mechanism of natural selection was able to see into deep time.

Keston (name derived probably from Roman word for town Chester-ton, though another theory in is Kes’s boundary stone) is a little to the north of the path of the London Spiral, but in this part of London public transport is sparse, so the walk is a connector back on to the spiral.

We have walked alongside the Ravensbourne already on the inner circles of the spiral, both below Hilly Fields at walk 14 – Honor Oak to Millennium Peninsula, and at 25 – Beckenham to Eltham Palace, (which started at Ravensbourne station, and on crossing the stream we passed a raven standing in the bourne)

Exploring the North Downs

The London Spiral is a 250 mile walk circulating around the metropolis to the Thames at Gravesend (more), which began in summer 2015 and is now in its outermost sweep, heading across the countryside, south of Croydon. The spiral crosses the North Downs, an extensive, rolling series of hills, taking in the high ground, woods and farm land, then dropping down to the valleys, across arterial roads and railway lines. For the traveler, whichever route south or north is chosen, highways and railways hug the valley floor: everything is hemmed in, everyone is in transit. But for the walker the landscape offers open views, undulating terrain, tree cover, fields, quiet old villages, and a sense of a rural past.

Approximate Route: This walk is at the onset of winter, starting at Upper Warlingham station, climbing to Farleigh, and on to New Addington, a fully planned town built from the 1930s to the 1960s like Sim City, which from the vantage of the Google Maps ‘satellite’, looks like an airbrushed animation, a piece of Pixar: new addington We had a couple of readings from John Grindrod’s book Outskirts, as John’s experience of growing up in New Addington has shaped his knowledge of the greenbelt, and the new buildings of Britain. A bit like John Grindrod I grew up on the last street of a housing scheme in Edinburgh, so this book has been like a family photo album of a life lived, both familiar and bizarre, as well as a historic account of how and why these places came about.

Stage 39 – Happy Valley

Sunday 11th November 2018, 1pm.

The next stage of the London Spiral should cut across Coulsdon and on to Kenley, but that would miss out on the joy of a climb to Farthing Down and descent into Happy Valley.

So we will follow the London Loop for this stage.

rainbow above rowan priest hill ewell

On this walk from Ewell West station we pass across Priest Hill, until recently a grubby suburban playing field of no great loveliness, which was bought by Surrey Wildlife Trust, who tore down the buildings, ripped up the paving, shipped the waste off to some unspecified place, then just left the site to re-wild.

It’s all scrub right now, and seems empty of animals, except an occasional dog and walker, but some early adopter trees are making the most of it. In a few years it will be woodland, managed meadow, heath. It’s not like a park, it’s not roamable; the sky stretches wide across it, and birds swoop into bushes and tall grass clumps.

We’ve seen a few reclamations like this on the spiral walk; there was the semi-suburban house knocked down and turned into a tiny park in stage 13 Palace Road Nature Garden, south London, a little oasis; there’s the greening going on in east London along the Lee Valley and Mile End Park; a whole array of housing in Barking alongside the Abbey was bought back by the council to recreate the Abbey gardens, re-establishing an appropriate space around the ancient building; and often where developers start to put up blocks of flats, they are creating show-garden green corridors in the urban space, publicly accessible and sometimes inspirational, like in Battersea by the Thames.

Perhaps a charitable organisation could be set up whose job was to accept property bequeathed by people passing on, along with a fund to pay the cost of demolishing, and legal fees, and planting costs, until slowly but surely green gaps would appear in the housing belt and some of those would join up to make gardens, and community spaces, and parks. Some property couldn’t be turned into land, like an apartment, but it could be sold to raise funds for the other spaces.

And the value of these spaces would be huge, because you could immediately envisage a property in the space on the market for thousands of pounds.

But will these greening efforts last a hundred years? Trees live into deep time. When it comes to nature man moves too fast, too acquisitive, too rapacious, too uncaring. Best of luck Priest Hill.

The London Spiral, a walk around London from the inside out, has reached its home straight along the south of the city, and over the next few stages will be crossing those parts of Surrey and Kent that melt into the edge of the metropolis, en route to Gravesend. We’ve reached Coulsdon, south of London, and will soon be home.

Stage 37 – Horse Country

When you get to the outskirts of London and reach the first fields, what do you find?


hinchley wood horses

Like a saddle belt strapped around the city  it seems every spare field is given over to the accommodation of horses. There’s not really space for them in those paddocks, not for an animal built to roam an open plain, but we keep them in their hundreds.

The equine life reaches a crescendo here in West London – we already passed Kempton Park race ground on the previous stage of the walk, and crossed the Thames at Hampton Ferry to Hurst Park, now a suburb but until the 1960s the home of Hurst Park race track (Racecourse of the past – BBC archive), which drew tens of thousands of spectators on a bank holiday. Now we begin this walk at Sandown Park race course and continue south to Epsom Downs, domicile of the Derby.

Epsom Racecourse is situated on the chalk ridges known as the North Downs, which cross the county of Surrey in southern England. The Epsom Derby course is a mile, four furlongs, and 10 yards in extent, and curved like a horseshoe.

Rosie said there are 22 yards in a chain; 10 chains in a furlong; 8 furlongs in a mile.

For a sense of the excitement of the Derby, search for Epsom Derby on Google images:

One of the most infamous incidents in the history of the Derby took place at Tattenham Corner in 1913, when militant suffragette Emily Wilding Davison climbed beneath the running rail and threw herself under Anmer, owned by King George V. She never regained consciousness and died a few days later from internal injuries … read more

Stage 36 – Feltham to Hampton Ferry

Fire and Water – a walk from Feltham to the Thames

In this hot weather southern England resembles Tuscany, yellow and scorched, as dry as concrete. The parkland at Hanworth has been burnt, most likely by local lads trying their pyrotechnic skills; you can smell the carbon, and birds flit in amongst the seedlings.

hanworth park scorched

Although it’s hot the rivers are not all dried up, there’s been rain. Just as well for it’s here that Thames Water pumps water out of the Thames, filters it, purifies it, and sends it coursing through a network of pipes to our kitchens and bathrooms.

At Hampton you can see the waterworks from the pavement, but it’s more impressive from the air – see this picture from Black & Veatch (PDF source):

I often say the London Spiral is defined by the crossings of the Thames, you can only continue where there’s a crossing (read more about this and other crossings Here), but the truth is that in west London the route was shaped more by where Heathrow airport is – I wanted to walk past it and not a trajectory half a mile inside – so the Hampton ferry is a little to the east of the spiral line.

Walk the flight path to Heathrow’s third runway

Go see something that will soon be gone – the countryside around Heathrow.

flight pathFuture flight path, how it looks today

This walk starts off a bit like last month‘s Hillingdon Trail, across marsh lands and meadows along the River Crane. But there’s a difference – the planes: they’re getting bigger and closer. This land will soon be gone, beneath Heathrow’s Third Runway.

In June 2018 the UK government announced its support for a new runway on the land to the north of the current site –

This walk is an opportunity to gaze into the future, seeing what is there now, and what is coming, as the quiet countryside and flat grassy fields give way to modernism and engineering on a colossal scale. If you’re interested in infrastructure, join the walk.
