I have never been so relieved to see a set of keys left under a terracotta pot in my entire life. The journey from Jerez Airport to our Rota holiday home had been straightforward enough, a hire car humming along the A-49 with the windows down and that particular Andalusian warmth already pressing through. My partner had insisted on navigating, which should have been my first warning. Three wrong turns later, we found ourselves down a dusty track between orange groves, the satnav cheerfully announcing we had arrived at a field of goats.

The goats, I must say, looked thoroughly unimpressed.

By the time we actually located the property, a charming whitewashed villa with a proper Spanish courtyard and bougainvillea spilling over the walls, we were forty minutes late and I had worked myself into that peculiar British state of apologetic panic. The key holder had long since left. The terracotta pot, mercifully, had not.

I will not dwell on how long I spent trying the wrong key in the lock, nor on the small comedy of me attempting Spanish phrases at the neighbour's cat, which watched from the wall with the detached superiority cats everywhere seem to perfect. The door finally yielded, and we stepped into cool tiled rooms that smelled faintly of jasmine and cleaning products, our suitcons still radiating airport chill against our legs.

The real revelation came the next morning. I had planned our walking routes with the precision of a military operation, poring over coastal paths near the Parque Natural de la Brena y Marismas del Barbate. We would stride along cliff tops, I declared over breakfast on the terrace, watching the Atlantic crash below. We would be vigorous. We would be intrepid. We would, as the English say, get our steps in.

The weather, however, had consulted no one. By ten o'clock the temperature had climbed past thirty degrees, and by eleven my intrepid companion was melting into a puddle of factor fifty and regret. The coastal path, when we finally reached it, shimmered with heat haze. The pine trees offered scattered shade, but the exposed stretches between them felt like walking through a hairdryer. I had packed hiking boots, proper socks, a rucksack with emergency supplies. What I had not packed was sufficient humility.

We managed perhaps two kilometres before retreating to a beach bar in Zahora, where I sat with a tinto de verano and contemplated my errors. The locals, sensibly, were nowhere near the paths at midday. They were at home, or in shaded courtyards, or perhaps having sensible siestas while mad foreigners roasted themselves for sport. I watched a group of Spanish teenagers splash into the surf without apparent effort and felt a complicated mixture of admiration and mild shame.

The lesson, once my pride had cooled along with my body temperature, was simply to surrender. We adapted, as one must. Early mornings became our walking time, setting out at dawn when the air still carried night coolness and the light lay soft and golden across the marshes. The paths through the pines near the Torre de Trafalgar felt almost enchanted then, woodpeckers tapping somewhere overhead and the sea visible in flashes between the trees. By midday we had earned our retreat, our books, our long lunches with gazpacho and chilled wine.

One evening, walking back from a late swim at Cala del Aceite, I realised how completely the rhythm had shifted. My planned vigorous hiking had become something gentler, more observant. We noticed the way the fishermen mended nets in Rota's harbour, the particular blue of the boats, the old men playing dominoes with the concentration of chess masters. The heat that had defeated my ambitions had also slowed me enough to actually see where I was.

I still maintain that my original walking plans were structurally sound. They simply belonged to a different climate, a different me. The Rota I discovered was one of early starts and lingering dusks, of finding shade like a survival skill, of understanding that the coast here demands a certain relationship, a certain patience. I left with calves still untested by serious distance but with something better, I think, a sense of having finally paid proper attention. The goats, had they known, might have approved.
