I should have known the holiday proper had begun the moment my sat-nav tried to drown me in a canal. There I was, trundling through the flatlands of Groningen, convinced I was being clever by ignoring the main road and following some "scenic route" I'd found on a forum. The voice calmly instructed me to "turn left now," which would have been splendid had there been anything resembling a road. Just reeds, water, and the distinct feeling I'd annoyed several very Dutch ducks.

Three-point turns in a Fiat Panda are not my forte. Neither, apparently, is reading maps. But eventually, after what felt like a pastoral odyssey through cabbage fields that stretched to infinity, I spotted the sign for Lauwersoog. Proper sign, proper tarmac. I nearly wept.

The property sat tucked near the harbour, that particular sort of northern Dutch architecture that looks modest until you notice how everything has been thought through. White-rendered, unassuming, with windows that seemed to wink at the grey sky. I'd booked it chiefly for the location - the Wadden Sea on one side, the Lauwersmeer on the other - but arrival day had already taught me that plans were merely suggestions.

Dumping my bags with the enthusiasm of someone who'd been driving in circles for two hours, I decided to "just stretch my legs." This is how the best discoveries happen, isn't it? The deliberate wanderers find museums. The lost find magic.

I walked without purpose along the harbour front, where fishing boats sat low in the water and a man in overalls was mending something with the concentration of a surgeon. A cat watched me from a windowsill with the undisguised contempt cats reserve for tourists. I turned left where I should have turned right, or perhaps it was the other way round. The point is, I had no idea where I was going.

The path became a track, then something looser, then I was standing on a dyke with the wind making my eyes water. Before me stretched the Lauwersmeer, that strange, still body of water where the sea once pushed through. The light was doing that flat northern thing, no shadows, everything slightly silvered. I'd stumbled onto a birdwatching spot, apparently, though I had neither binoculars nor the faintest idea what I was looking at. A heron, perhaps. Something that might have been an egret. To me they were all "birds, quite large," but the stillness was extraordinary. No one else about. Just me, the wind, and my own slightly ridiculous breathing after the climb up.

I stayed until my ears went numb, then wandered down the other side, finding a tiny beach where someone had built a driftwood shelter, all angles and optimism. Inside sat a plastic chair, weathered to the colour of old bone. I sat in it. Felt immediately, absurdly, like I'd discovered a secret clubhouse. The sort of thing you'd have killed for at ten, and at forty-something feels like an unexpected gift.

Hunger eventually drove me back, though I took a different route again, past a farm where geese honked in chorus, through a copse where the path simply stopped being a path and became squelch. I emerged somewhere I didn't recognise, laughed out loud at my own uselessness, and eventually found a road that seemed familiar if I squinted.

That evening, warming my hands on a mug of something in the property's compact kitchen, I watched the darkness come down over the water. No dramatic sunset, just a gradual dimming, the way northern evenings do. I'd done nothing remarkable by any objective measure. No ticked boxes, no photographed landmarks. Yet I felt peculiarly wealthy, as though I'd been let in on something.

The next day I would try to find that driftwood shelter again, armed with coffee and better boots. I failed, naturally. Took wrong turns, ended up at a completely different beach, found a dead-end road where an elderly woman explained, in Dutch I barely followed, that I'd missed the turning "obviously." Obviously.

I found other things instead. That's rather the point of Lauwersoog, I think. It doesn't present itself. You have to be willing to get slightly lost, to trust that the wrong path might be the right one, to accept that your sat-nav has limitations and so, more importantly, do you.

By day three I'd stopped trying to find anything at all. Just walked, turned where it looked interesting, ate where I found somewhere open. I discovered a tiny smokehouse selling fish so fresh it practically introduced itself, found a bench facing nothing in particular that became my morning ritual, stumbled into a conversation with a retired engineer who'd sailed these waters for forty years and had opinions about everything, shared slowly, between puffs on his pipe.

The mishap of arrival had set the tone. I'd been humbled by technology, by landscape, by my own overconfidence. And in that humility, I'd found something I didn't know I was looking for. Not peace exactly - I'm too restless for that. Something more like permission. To be uncertain, to wander, to find without seeking.

On my last morning I sat again on that first dyke, the one I'd found by mistake. The heron was there, or its cousin. The light did its silver trick. I thought about all the holidays I'd planned meticulously, all the sights I'd raced between, all the satisfaction of checking things off. This had been none of that. This had been better.

I drove home the long way round. Obviously got lost again. Obviously didn't mind terribly much.
