The valley arrived before I did. The train from Interlaken slips between two walls of rock, and the world narrows to a green floor, a thread of river, and cliffs so sheer they seem drawn rather than built. Somewhere above, a ribbon of water leaves the rim and falls so far it turns to mist before it lands. By the time we stepped down at Lauterbrunnen, the place had quietly rearranged what a landscape could be.
Seventy-two waterfalls, they say, come off these walls. I counted on the first afternoon and gave up somewhere in the teens, which is probably the honest number to arrive at. The famous one is the Staubbach, almost three hundred metres off a bare cliff in a single fall, thunderous in spring and, by August, barely there. Stand under it once, then stop looking at the named things and start noticing the rest: the small falls that only show after rain, the cowbells, the smell of cut grass and cold stone.
Lauterbrunnen makes the obvious base, and the first day belongs to the valley floor: flat, walkable and mostly free, which after the sticker shock of a Swiss coffee is its own kind of relief. The lane to Stechelberg runs past barns and meadows to the Trümmelbach, ten glacier-fed falls thundering through the rock itself, lit and laddered so you can climb up among them. Back out in the light, I did nothing in particular, which is the one thing the valley floor really asks of you.
There is only one sensible way out of the valley, and that is straight up. No road reaches the villages on the western shelf, so a cable car hauls you out of Lauterbrunnen and a small train trundles the rest of the way to Mürren, a single street of dark timber hung above the drop. Across the gulf of air stand the three everyone comes for, the Eiger, the Mönch and the Jungfrau, close enough to read the weather off their faces. The sky held, so I carried on up: the cableway to the Schilthorn ends at a revolving terrace where the panorama runs to the horizon, and it turned me through a full circle twice before I quite believed it.


The third day belongs to the railway, because here the railway is the point. From the other shoulder of the valley, a cogwheel train climbs through Wengen to Kleine Scheidegg, a windswept saddle laid right at the foot of the Eiger's north face. This is where the lines meet, and where the most improbable of them begins: the Jungfrau Railway, bored straight up through the mountain in the early years of the last century, climbing in the dark to the highest station in Europe.
I did not conquer these mountains. I was lent a morning on them, and sent back down before the cloud came in.
The train surfaces at the Jungfraujoch onto a different planet: thin air, hard light, and the long white tongue of the Aletsch, the largest glacier in the Alps, curving away below as if the whole range had been poured and frozen. Go early. The summit makes its own weather, and the clear nine o'clock I was given was a whiteout by noon. There is no rushing a place like this. You stand still, breathe the thin air slowly, and let the scale of it land.
The last evening belongs back down in the green. After the glare of the snow the valley feels almost tropical, loud with water and warm with hay. We ate early and walked the lane while the cliffs went gold and then violet, the Staubbach still falling somewhere in the dark. Five nights is enough to learn the shape of the place, and nowhere near enough to leave it willingly.
