One Hill, Four Seasons: What I Learned From Climbing the Same Mountain Again and Again

There's a particular itch that every peak-bagger knows well. It's the one that says the list matters more than the walking, that a day on a new trig point is somehow worth more than a day on an old friend. I spent years scratching that itch — Wainwrights, Marilyns, the odd Munro when the fuel budget allowed. Then, somewhat accidentally, I broke the rule. I climbed the same hill twice in a month. Then twice more that year. And it changed how I think about the whole game.

The hill in question was Pen y Fan. Yes, that one — the busiest summit in the Brecon Beacons, the one with a motorway of a path up from the Storey Arms. Hardly a wilderness pilgrimage. But that's rather the point. The two mountains rule doesn't require remoteness or rarity. It requires repetition.

January: The Hill in Ice

My first deliberate return visit was a January dawn start, headtorch on from the car park, breath freezing on the buff pulled over my face. The path I knew so well had vanished under a crust of ice, and what's normally a forty-minute jaunt became a careful, crampon-assisted two hours. The summit tor, usually mobbed by mid-morning, was empty and silent, rimed white like something out of a Scottish winter.

Here's what struck me: I'd been up this hill perhaps a dozen times and never really looked at it. Familiarity, it turns out, is a kind of blindness. When you're chasing a new summit, your brain is busy cataloguing — the gradient, the terrain, the views. When you revisit, all that processing is done, and something else opens up. You notice the hill itself.

April: The Hill in Flow

Spring brought a different lesson. A April return, after days of rain, turned the usually docile streams off the main path into roaring brown torrents. The Nant Sere crossing — a rock-hop I'd never given a second thought — demanded actual decision-making. The hill I thought I knew had rearranged itself.

This is the quiet argument of the two mountains rule: a mountain is not a fixed object. It's a weather system, a season, a water table. Fifty different hills in fair conditions will show you fifty versions of the same day. One hill in foul conditions will show you something no new summit can.

August: The Hill at its Worst (Sort Of)

Come August, I went at dusk, partly to test myself against the season's true enemy: the midge. Anyone who's stood still too long on a warm Welsh evening knows this battle. I reached the summit sweaty, bitten and mildly furious, just as the light went gold across the Beacons.

And I'll be honest — I sat up there longer than I meant to. No list to tick, no new height to log, no pressure to move on to the next thing. Just a hill I knew intimately, wearing its best clothes. There's a version of summit-bagging that's essentially consumption: collect, tick, next. Revisiting is something closer to a relationship.

November: The Hill in My Head

The fourth visit was the strangest. Grey, low cloud, nothing to see, a bit of a drizzle. Objectively the worst of the four days. But I'd arrived at the car park with a head full of noise — work, family, the general grind — and somewhere on that boggy, featureless pull I realised the noise had stopped.

The hill hadn't changed at all. I had.

The Case for Going Back

I'm not suggesting you abandon your lists. Targets are brilliant — they get us out the door in the rain and give structure to a hobby that could otherwise drift. But I'd wager there's a hill within an hour of you that you've climbed once, filed away, and never returned to.

Try it again in a different season. Go at dawn instead of midday, or in the rain instead of the sun. Take someone who's never been, and see it through their eyes. Or go alone, with no agenda at all.

You'll learn the hill's moods, its secret lines, its quiet corners. More to the point, you'll learn what you're actually doing out there — because a repeated summit is a mirror, and a new one is just a photograph.

One hill, four times a year. That's the two mountains rule. Chase your summits, by all means. But make sure at least one of them is a repeat.
