I have to be honest with you: I had never heard of Sjusjoen before this trip. My mate Dave mentioned it in passing, said something about "proper Norwegian wilderness" and "cabins with actual log fires," and before I knew it I had booked a week's stay at a little place in Hedmark. I did not check a map. I did not check the weather. I packed three pairs of shorts and a optimistic attitude.

The journey from Oslo started well enough. Train to Lillehammer, then a bus that wound through pine forests so dense and green they looked almost fake, like someone had cranked the saturation up too high. I felt smug, watching the scenery roll past, already imagining myself striding across mountain ridges like a Nordic god. Then the bus driver announced my stop, I stood up with too much enthusiasm, and promptly whacked my head on the luggage rack hard enough to make the entire vehicle wince in sympathy. I stumbled onto the pavement clutching my forehead, rucksack tangled round my legs, while an elderly Norwegian woman handed me my dropped water bottle with the sort of pitying smile usually reserved for toddlers and very old dogs.

The cabin sat about a mile from the bus stop, and I walked it with a lump already forming above my eyebrow. The road curved past a small lake, Sjusjoen itself I presumed, the water so still it held perfect reflections of the surrounding hills. My head throbbed but my spirits lifted with every step. The air smelled of pine resin and something else, something clean that I cannot properly describe. Cold and sharp and somehow green.

The cabin exceeded every modest expectation. Proper timber construction, a deck that caught the afternoon sun, and inside that glorious musty smell of woodsmoke and old wool blankets. I dumped my ridiculous shorts on the bed and immediately felt foolish. It was June, technically summer, but we were still over nine hundred metres up and the temperature had barely nudged fourteen degrees. The forecast I finally bothered to check showed rain moving in, then out, then in again with the indecisive energy of a cat at a door.

I had planned coastal walks. I say coastal - what I mean is lakeside, because Sjusjoen is inland, but in my ignorance I had somehow conflated Norwegian lakes with dramatic seascapes. The local trails followed the water's edge through birch woodland, then climbed into proper mountain terrain. I set out the first morning in my one pair of long trousers and a borrowed fleece I found in the cabin cupboard, feeling like a child wearing their parent's clothes.

The weather turned within an hour. Sunshine gave way to horizontal rain that somehow came from three directions simultaneously. I sheltered under a rock overhang, soaked despite my waterproof jacket's optimistic claims, and watched the lake transform from mirror to grey turmoil. My phone showed more of the same for the week ahead. I laughed, there on that mountainside, water dripping off my nose. All that planning, all that imagining myself as some rugged outdoorsman, undone by basic meteorology and my own refusal to research anything properly.

When the rain eased I walked back slowly, no longer rushing to conquer trails. The wet birch leaves shone silver. A pair of grouse exploded from the undergrowth and I yelped like a child, heart hammering, then laughed again at my own ridiculousness. That evening I sat on the cabin deck with a cup of something hot, watching mist roll across the lake, and felt something shift. The walk had been uncomfortable, briefly frightening, entirely unlike my imagined adventure. Yet here I was, present and alert and somehow more satisfied than if everything had gone to plan.

The week continued in this vein. I walked every day, adjusting routes according to weather that changed hourly. Some mornings dawned clear and cold, the lake surface glassy, and I would stride out with genuine confidence. By afternoon the clouds would gather, the temperature would drop ten degrees, and I would find myself hastily retreating or huddled in yet another improvised shelter. I learned to carry extra layers, to read the wind on the water, to abandon routes without the petulance that marked my first wet defeat.

One particular afternoon stands out. I had set out for a longer circuit, the sky promising enough blue to risk it. Three hours in, caught on an exposed ridge, a proper storm descended. Hail this time, stinging and relentless. I scrambled down to a small cabin marked on my map as emergency shelter, found it unlocked and stocked with firewood, and spent two hours drying my clothes and feeling absurdly grateful to strangers I would never meet. The storm passed. I walked the remaining distance in golden evening light, everything washed clean, my own mood similarly refreshed.

I never did have the warm-weather adventure I packed for. The shorts stayed folded, untouched, faintly embarrassing in their optimism. What I found instead was something better suited to me, though I resisted admitting this for several days. The uncertainty, the necessary adaptation, the small humiliations of poor preparation followed by the quiet pride of learning - this became the actual texture of the holiday.

On my final morning I walked one last time to the lake edge. The water lay perfectly still, dawn mist rising in thin columns. I stood there with my still-tender forehead, my borrowed fleece now feeling like my own, and understood that I would remember this trip less for any particular view achieved than for the slow, reluctant process of becoming someone who could exist comfortably within unpredictability.

The bus back to Lillehammer arrived on time. I boarded carefully, ducking the luggage rack with exaggerated caution, and caught the same elderly woman's eye. She smiled, recognition flickering, and I smiled back with the particular warmth of shared, unspoken understanding. We both knew what I was. The trick was that I no longer minded.
