Further down the gorge, the colours multiplied. Poplars and willows, turned mustard and tan by the arrival of autumn, spread along the banks of a stream. Fluttering flocksof sparrows exploded up from fields of sun-blasted wheat and barley. Grumpy-looking yaks turned to stare, like nosy neighbours.

We lunched in an orchard near the village of Stok before jumping into a Jeep and taking the winding road southeastwards into the hills at Hemis. “Better be Mr Late than a late Mr,” a sign cautioned, as we sped past in a whirl of sand.

The monastery we found had none of the carefree whoopee of Thiksey. While there had been a festivalrecently, its centrepiece had been something that translated as “the dance of death” and involved monks dressed as demons waving mummified human hands. Let your mobile ring out of turn there and you were likely to fall foul of a fearsome deity named Gyalpo Pager, a booze-loving 400-year-old harridan who would haunt you for ever if you dared take so much as a pebble from her temple.

Worse was on offer in the caves high in the cliffs above the building.

At a spot charmingly known as “the vultures’ place”, Hemis’s monks brave daytime temperatures as low as -35C to meditate alone for three months, three days and three hours — a brutal privation familiar to anyone who’s ever waited for a train at Ely station during the Christmas holidays.

It was almost enough to make me feel guilty about my own luxurious circumstances. Later, while I was lying toasty in the lantern-lit dining room of a tastefully modernised village house, there were monks up there with nothing but a wraparound yak-hair coat for company.

It used to be that the only way to see Ladakh was to rough it. Not any more. As those monks sipped freezing water from a silty mountain stream,I warmed my cockles with a peaty Laphroaig by a wood-burning bukhara stove. While they were reliant on occasional food parcels left by locals,I was sitting down to a four-course gourmet feast, served on starched tablecloths and copper plates, andfeeling a deep sense of spiritual achievement for merely being able to chew without getting out of breath.

Fuelled by a breakfast of strawberry porridge and fresh coffee, I headed somewhere even colder than their meditation perch. At 17,582ft, Khardung La is said to be the highest motorable pass in the world, two hours of terrifying uphill from the busy little town of Ley.

“Check your nerves on my curves,” ordered the sign on this one, withthe spangled wreckage of trucks in the ravines far below a trashed testament. It was via this pass that the caravans of the Silk Route used to bring in their costly cargos from China, although these days it’s all bellowing army trucks and frozen soldiers rather than opium, cloth and spices.

Both the colours and altitude knocked us sideways. Primary-dyed strips of prayer flags fluttered furiously in the freezing wind against a sharp background of white snow and blue sky. “KIKI SOSO!” roared Sidd. “LYARGYALO!” we roared back, completing the auspicious chant with chest-clutching effort.

The lack of oxygen was sending us all a little loopy. One of the party had collapsed in giggles, like a caned Californian. Another was pretending to talk to an invisible butler called Smithers. I became obsessed with slight variations on the same ­tedious joke. “This is the highest pee I’ve ever had!” I chortled, staggering through the snow to the world’s highest motorable lavatory block. “And that’s my highest wheeze! And my highest intense shortness of breath!”

“Drive like Hell and you will be there,” warned a sign on the way down, but all we could do was hoot with laughter.

Calm was only restored in theaptly named village of Chilling. Apt for two opposing reasons: for the bucolic atmosphere and warm, dappled light under the willow trees; and for the huge lumps of rock that kept crashing down the valley sides from the cliffs on either side.

From there, we clambered into a bobbing raft to paddle our way down the Zanskar Gorge to Nimoo, a prosperous village stretched along the Indus. Finding Nimoo wasn’t a problem, despite what the film might have you believe — the river took us straight there.

What was harder was taking your eyes off the spectacular rock form­ations on either side. There were teetering slices of dark red, maroon and khaki, pale bluffs that looked like giant sponge fingers, angular boulders perched so precariously on ledges, they seemed a sparrow’s sneeze away from tumbling down on top of us.

The swim in the river was probably ill advised. Sidd had warned against it, but, not having experienced glacial meltwater before, we were convinced any water that sparkled turquoise had to be inviting.

“Kiki soso?” offered Sidd as we sprang out the same shade of blue as the sky. “Very so-so,” I shivered, reaching for every layer of clothing within earshot.

Later that evening, recovering with a pot of darjeeling on the house’s roof, feeling a crinkly tightness across my sunburnt nose and cheeks, I watched fat grey snow clouds gathering further up the valley. Winter was coming. High above, a kestrel rode on the last of the day’s thermals.

A car braked and slowed on the road far below. I knew the spot well — it was where a sign read: “Don’t gossip — let him drive.”
