I had been dreaming of coastal walks and sunny afternoons in Groningen for weeks, so when my sat-nav cheerfully announced "you have reached your destination" while I was still very much in the middle of a field surrounded by sheep, I should have known the holiday gods were having a laugh at my expense. There I was, reversing down a narrow lane with a tractor looming in my rear-view mirror, convinced I had booked a charming cottage near the Wadden Sea, not an audition for Countryfile.

The mishap, as it turned out, was entirely my own doing. In my excitement, I had punched the postcode into my phone while sipping airport coffee and apparently transposed two digits, sending me twenty minutes in the wrong direction. The sheep, I must say, looked thoroughly unimpressed with my arrival. When I finally pulled up to the proper address in Vlagtwedde, my cheeks were still burning with that particular blend of embarrassment and relief that only a truly unnecessary detour can provide.

First impressions of the place, though, washed that awkwardness away almost immediately. The cottage sat quietly among greenery, with a tidy garden that practically begged for morning coffee outside. I had packed my walking boots with serious intent, you see. The plan was simple and rather smug: three days of brisk coastal hiking along the Wadden Sea, building up a healthy appetite for Dutch cheese and perhaps a beer or two. The weather forecast had promised sunshine. I had checked it obsessively, as though staring at my phone might bend the North Sea climate to my will.

I dropped my bags and set off that very afternoon, full of misplaced confidence. The path from Vlagtwedde toward the coast starts pleasantly enough, threading through flat farmland and occasional woodland. I was striding along, mentally composing my future boasts about Dutch hiking, when the sky began to do something I can only describe as theatrical. One moment, butter-yellow warmth; the next, clouds stacking up like grey pancakes. By the time I reached the edge of the Dollard estuary, a fine drizzle had settled in with the determination of someone who plans to stay for tea.

I stood there on the dyke path, waterproof jacket still triumphantly back at the cottage, watching my coastal ambitions dissolve into mist. The Wadden Sea, usually so dramatic at low tide with its exposed mudflats and wading birds, had retreated into a soft grey blur. A heron regarded me with what felt like sympathetic understanding. We were both damp and slightly defeated.

The thing about Groningen weather, I discovered, is that it does not apologise. It simply changes, sometimes within a single afternoon, sometimes within a single hour. I turned back, squelching slightly, and found myself taking a different route through the village of Bourtange. The drizzle lightened to something almost pleasant. The fortified star shape of the place, those remarkable earthworks from the Eighty Years' War, emerged through the haze like a watercolour painting. I would never have wandered there on my original plan, too busy charging toward the coast.

That evening, drying off with a cup of tea in the cottage garden, I laughed at myself properly for the first time. How quickly I had turned rigid about my own holiday, mapping every footstep in advance. The sat-nav mishap that morning should have been my warning. Some places simply refuse to be experienced through sheer willpower and a weather app.

The following days, I walked differently. Early mornings brought genuine warmth, and I covered good ground on the paths near Sellingen and along the Westerwoldse Aa river, where the water meadows looked almost Mediterranean in golden light. When clouds gathered by noon, I retreated to local cafes or explored the smaller paths through woodland near the German border, where the trees offered their own shelter. I stopped treating the changing weather as an obstacle and started treating it as the main character of the trip.

On my final morning, the sun returned with proper enthusiasm. I managed a proper stretch of the Wadden Sea coast near Nieuweschans, boots finally earning their keep on the salty dyke paths. It was glorious, honestly, but I think I preferred the humbler walks I had stumbled into by necessity. There is something about Groningen's quiet corners, the ones you find when plans dissolve, that feels more genuinely discovered.

I left my slightly scuffed boots by the door and packed my still-damp jacket with something like affection. The sheep, mercifully, were nowhere to be seen as I drove away.
