Ben Macdui is the second-highest mountain in Britain, standing at 1,309 metres (4,295 feet), and the highest in the Cairngorms National Park, that vast granite wilderness stretching across the heart of the Highlands. Today, we planned to stand on its summit. The forecast suggested a narrow window: calm and clear in the morning, storm by late afternoon. We packed for both. The plan was simple, start early(ish), summit and be safely down before the gales rolled in around 4pm.

Our route began at the Cairngorm Ski Centre, climbing out past the corries along the northern flank of the resort. Beyond that, the lifts and buildings fell away and we stepped onto the Cairngorm Plateau proper, a high, open expanse of rock, snow, and silence that feels closer to the Arctic than the rest of Britain.

It didn’t take long to lose the comfort of civilisation. As soon as we left the shelter of the ski area, the wind began to build, funnelling down through the Lairig Ghru, the great glacial trench that cuts clean through the Cairngorms. It’s eleven miles long and nearly 3,000 feet deep, carved by glacial ice over thousands of years.

The cloud base that was meant to lift simply didn’t. Within half an hour, the landscape disappeared into a white-out, horizon, sky, and ground blurring into the same shade of nothing. Despite the GPS and map, we were grateful for the old stone cairns that line the route, appearing out of the fog like a breadcrumb trail left by those who knew these mountains far better than us.

We reached the summit almost by surprise. The world was grey in every direction, the view a rumour rather than a reward. We found shelter on the leeward side of the summit cairn, pulled on extra layers, and ate quickly, the windchill made it feel like minus ten.

The return was meant to be straightforward, retracing our route back across the plateau. Usually, I find out-and-back walks dull, but today it felt more like a game of hide and seek with the mountains, glimpses of cliffs and corries flashing through gaps in the cloud before they vanished again.

Then the weather turned. Our window closed early. The wind came up with sudden and furious intent, making every step a negotiation. There’s something humbling about realising that air alone can shove you off balance, it felt so powerful like it could take me off my feet. By the time we dropped back below the cloud, we were tired, windburned, and exhilarated, exactly as the mountain intended.
