I have to be honest with you: I had never heard of Monterchi before this trip. My partner found the place on some holiday letting site at half past midnight, which should have been my first warning. Still, Umbria sounded romantic, the photos showed a honey-coloured stone farmhouse with a pool, and I was three glasses of wine deep. I clicked "book" with the confidence of someone who had absolutely no idea what they were doing.

The journey from the UK was straightforward enough. Flew into Perugia, hired a Fiat so small I had to fold myself in half to reach the pedals, and set off into the green heart of Italy. The trouble began about twenty minutes from Monterchi when my phone decided this would be the perfect moment to die. No charger, no map, no signal anyway because apparently Umbria specialises in charming medieval villages built inside mobile dead zones. I drove in what I felt was roughly the right direction, growing increasingly warm and increasingly lost.

Here is where the mishap occurred. I spotted a sign pointing toward "Monterchi" and followed it triumphantly up a winding road, feeling rather pleased with my primitive navigation skills. Ten minutes of increasingly narrow lanes later, I arrived at what I can only describe as someone's private vineyard. A very Italian gentleman emerged from a shed, looked at my Fiat, looked at my face, and informed me that I had followed the sign for "Monte Chi" not "Monterchi." Two entirely different places, apparently. The sign had been weather-beaten, the letters slightly spaced, and I had done what any tired, hungry Brit would do: I had seen what I wanted to see.

He found this hilarious. I found it less so, particularly when reversing back down his gravel drive scraped what I suspect was a significant amount of paint from the hire car.

Proper directions obtained, I finally reached the farmhouse as afternoon was tipping into evening. And I will say this: the place immediately made the getting-lost worthwhile. The property sat among olive groves with views that rolled out like a painting, all soft hills and distant cypress trees. The stone walls were warm to the touch, the pool glittered invitingly, and somewhere nearby a cockerel was having opinions about the time of day.

My plan had been walking. Proper walking, ambitious walking, the kind that justifies multiple courses at dinner. I had researched trails through the surrounding countryside, mapped routes to nearby hill towns, imagined myself striding purposefully through sunflower fields like someone in a travel brochure. The weather, however, had other ideas.

The first morning arrived hot. Not pleasant English summer hot. Proper Italian August hot, the kind that hits you like a damp wool blanket when you step outside. I attempted a walk anyway, setting off at what I thought was an early hour until I realised Italians consider eight in the morning practically midday. Within forty minutes I was a puddle. The path I had chosen, described online as "gently undulating," turned out to be the sort of incline that makes you question your life choices and your calf muscles simultaneously.

I retreated to the farmhouse pool and spent the afternoon floating with the dignity of a man who has accepted his limitations.

The heat broke that evening with a spectacular thunderstorm. Rain lashed the hills, lightning flickered across the valley, and I sat on the covered terrace with a glass of local wine feeling rather smug about my decision not to be halfway up a mountain. The morning brought cooler air, fresh and washed clean, and I set off again with renewed optimism.

This time I walked to Monterchi village itself, perhaps twenty minutes along a lane shaded by oak trees. The place is tiny, perched on its hill with the sort of quiet that makes you speak in lowered voices. I found the famous Piero della Francesca fresco, the "Madonna del Parto," in a small museum. A pregnant Mary, serene and monumental, painted for this specific village centuries ago. I stood before it rather longer than I expected, thinking about how places this small can hold something so significant, how you can stumble upon extraordinary things simply by being willing to get slightly lost.

The weather continued its pattern throughout the week. Mornings of building heat, afternoons of intense sunshine that drove me back to shade and water, occasional evening storms that cleared the air for the next day. I adapted, as one must. Walks became early, became shorter, became explorations of the immediate valley rather than ambitious treks. I discovered a path through woodland where wild boar had rooted among the leaves, found a viewpoint where I could see across to Tuscany, wandered down to a tiny stream where dragonflies hovered in the cool pockets of air.

One morning I walked to a neighbouring hamlet, following a track between fields of sunflowers that had turned their heavy heads to face the sun. An old woman was hanging washing outside her house. She watched me pass with the unsurprised gaze of someone who has seen many sweaty English people trudging past her property. "Caldo," I offered, because my Italian extends to about six words and weather commentary feels universally appropriate. She agreed, emphatically, and offered me water from her outside tap. It was so cold it made my teeth ache. I stood in her yard drinking like a grateful horse while her cat wound around my ankles.

By the end of the week I had abandoned any pretence of serious hiking. The heat had become my companion rather than my adversary, something to plan around rather than battle against. I walked in the cool of early morning, rested through the fiercest hours, emerged again as evening brought golden light and manageable temperatures. It was a different rhythm, slower and more observant, and I found myself noticing things I would have marched past in my original ambitious plans: the particular buzz of cicadas in different trees, how the quality of light changed the colour of the hills from hour to hour, the way village life continued around me barely perturbed by my presence.

On my final evening I walked up to Monterchi one last time, arriving as the sun was dropping behind the western hills. The village was quiet, a few locals gathering in the small piazza, children playing where the street widened. I sat on a bench and watched the sky turn through shades of apricot and rose, thinking about my wrong turn on arrival, my abandoned hiking plans, my general incompetence with directions and heat management. I am not, I reflected, a natural adventurer. I am someone who follows weather-beaten signs to private vineyards and calls it exploration.

But sitting there, with the day cooling into evening and the first stars appearing, I felt entirely content with this version of myself. The heat had forced a pace I would not have chosen, and that pace had revealed a place I would otherwise have hurried through. Sometimes getting lost and getting warm and getting things slightly wrong leads exactly where you needed to be.

The cockerel had opinions about this too, I suspect. But by then I had learned to ignore him.
