The Sat Nav had other ideas about how to reach our cabin near Treungen. Instead of following the sensible road through Gautefall, it decided we absolutely needed a detour down what I can only describe as a farm track masquerading as a through road. Three miles in, we met a very unimpressed sheep standing in a puddle that turned out to be rather deeper than it looked. I waded out to move the poor creature along, discovered my wellies had a hole, and spent the rest of the journey with one sodden foot pressed against the heater vent. My partner found this hilarious until we realised the track was a dead end and had to reverse the entire way back past the same sheep, who now looked deeply smug about the whole affair.

By the time we found the actual turning for our NOVASOL cabin, the October afternoon was already fading into that particular Norwegian half-light that makes everything feel slightly magical and slightly ominous all at once. The trees, heavy with autumn colour, seemed to lean in to inspect us as we crunched up the gravel drive. Birch and aspen glowed yellow against the dark spruce, and the air carried that clean, cold smell of approaching winter - woodsmoke, damp earth, and something indefinably mountainous.

The cabin sat perfectly in its clearing, windows warm against the gathering dark. I hobbled out with my ruined boot squelching embarrassingly, and immediately noticed how the season had prepared the place for us. A stack of birch logs waited under a lean-to, their pale bark almost luminous in the dusk. The grass was stiff with frost in the shadows, though the afternoon sun had kept the south-facing deck clear. Someone, presumably the owners, had hung a string of solar lights along the railing - not the tacky sort, but small warm globes that looked like they'd been left there since summer and simply refused to acknowledge autumn's arrival.

Inside, the cabin breathed warmth and that particular stillness of mountain places. The pine walls had darkened with age and woodsmoke to a honeyed amber. I made straight for the wood-burning stove while my partner investigated the kitchen, and we both independently discovered how thoroughly the season had shaped the place. The stove dominated the living area not as decoration but as genuine necessity; even now, in early October, the temperature dropped sharply after sunset. I found matches and kindling in a tin marked with faded Norwegian script, and felt unreasonably proud when the first flames caught.

The kitchen window framed a view that stopped my partner mid-sentence. The lake below, Nisser I later confirmed, lay perfectly still, reflecting the last salmon-pink of sunset and the first prick stars. Around it, the forest rose in tiers of colour - the green-black of spruce, the copper of birch, the occasional startling red of rowan berries. Autumn here was not gentle decline but vigorous, almost aggressive display, the landscape throwing everything it had at the coming dark.

I stood there with my damp sock, watching a single leaf spiral down from somewhere above, and felt that particular melancholy-hopeful feeling that autumn always brings. The cabin, I realised, was built for this exact transition - the deep overhangs that would soon shed snow, the storage for skis and poles in the entrance, the drying rack above the stove where tomorrow our walking boots would steam companionably. Summer visitors would have lived differently here, eating outside, swimming perhaps in that cold lake. We were inheriting a different place entirely, one preparing for retreat and endurance.

The wood stove crackled, settling into its rhythm. My partner produced coffee and something cinnamon-scented from the provisions we'd brought from Kragero. We sat with the darkness pressing against the windows, warm and enclosed and slightly stunned by the quiet. Somewhere outside, an owl began its questioning call. The sheep, I imagined, was still standing in its puddle, laughing at tourists.

That first evening set the pattern. We walked the forest trails as the leaves fell around us in soft flurries, each day's route slightly different as the undergrowth thinned and new views opened. The lake, when we ventured down, grew daily more forbidding, its clear summer shallows giving way to grey depths that promised cold without mercy. We gathered mushrooms one morning after rain, slightly terrified by our own daring, and fried them with butter and nothing else because the cabin kitchen encouraged simplicity.

The weather shifted constantly, autumn's indecision written in fog one morning, brilliant sunshine the next, once a brief snow shower that whitened the deck and vanished by noon. Each change reshaped the landscape entirely. The same view from the kitchen window became six different paintings in as many days. I found myself checking the forecast less for planning than for curiosity, surrendering to whatever the season offered.

By our final morning, proper frost had arrived, silvering the deck and making the gravel drive crunch with new authority. The rowan berries had mostly fallen, leaving bare architectural branches against a sky that seemed higher, more distant than before. I packed the car with the particular sadness of leaving a place that has started to feel like shelter, while my partner took one last photograph of the cabin with its solar lights still glowing faintly against the pale morning.

The sheep, mercifully, was nowhere to be seen as we navigated correctly back to the main road. But I checked the mirror anyway, half-expecting to find it watching from some gatepost, shaking its head at our incompetence. The trees closed behind us, and Treungen retreated into its autumn stillness, waiting for winter's proper arrival and whoever would next come to borrow its transitional beauty.
