Itinerary · for one

Wales · the Cymru week

Seven nights through Wales at the late-September cusp · solo · rental car from Cardiff. One night in Cardiff — Cardiff Castle (the Norman keep on the Roman foundations, restored as Victorian fantasy by William Burges in 1860s), the Victorian arcades of the city centre (six covered arcades), the National Museum, Cardiff Bay barrage + the Senedd Welsh parliament, Tiger Bay seafood at the Norwegian Church. Drive west to Pembrokeshire for two nights — the 186-mile Pembrokeshire Coast Path is one of the National Trails, walk a 5-km section at St Davids Head, the smallest city in the UK (St Davids, population 1,800), the puffin colony at Skomer Island (May-July only, missed in September), the medieval walled town of Tenby with the painted Georgian houses on the south Pembrokeshire coast. Drive north 5 hr to Snowdonia for three nights — Yr Wyddfa (Snowdon) 1,085-m summit via the Llanberis Path (4 hr up, 3 hr down, the easiest route), Snowdon Mountain Railway alternative (if knees can”t do the descent), Cadair Idris day-hike, the slate-quarry villages of Llanberis + Blaenau Ffestiniog (UNESCO World Heritage for the slate-landscape since 2021), Portmeirion (the Italianate fantasy village built by Sir Clough Williams-Ellis 1925-75), the Llanddwyn Island walk on Anglesey. One final night in Conwy on the Anglesey-coast side — the medieval walled town with the complete 1283 Edward I city walls still encircling the town, Conwy Castle on the headland, Beaumaris Castle across the Menai Strait on Anglesey, and a last drive back south to Manchester for the long flight home.

Wheels down at Heathrow. Then the long week of the Cymru.

Out of Hong Kong on a Friday night, Heathrow by Saturday morning, Cardiff by Saturday afternoon — Cathay direct + GWR train, fifteen hours all in. Seven nights ahead through Wales — one in Cardiff for the Capital and the Castle, two in Pembrokeshire on the south-west tip for the coastal-path walks and the puffin season''s tail (just before the migration south), three in Snowdonia for Yr Wyddfa''s 1,085-m summit and the slate-quarry villages of the north, one final night in Conwy on the Anglesey side for the medieval walled town. Late September is the cusp — end of the school summer, water still warm for swimming, the heather on the Carneddau still purple, and the Welsh weather at its most cooperative window.

Chapter 01 · the story

Cardiff opens with a Norman keep dropped into the middle of a modern city, ringed by Bute Park and Victorian arcades. Then the road bends west and the country empties out until it is only the coast path, the cliffs, and the gulls.

Read the story Collapse

Cardiff Castle sits inside the city the way other cities sit around their castles. Step off the train at Cardiff Central, walk ten minutes north past the Principality Stadium, and the curtain wall is suddenly there — a 12th-century Norman keep on a Roman foundation, with William Burges’s Victorian-Gothic apartments grafted onto the south wing in the 1860s. Behind it, Bute Park stretches two and a half miles along the River Taff, the Marquess’s old kitchen garden now the city’s lung.

The Victorian arcades thread the streets behind St Mary Street — Royal Arcade, Castle Arcade, Morgan Arcade, Wyndham Arcade — six covered shopping streets in iron and glass, built between 1858 and 1921 when Cardiff was the world’s busiest coal port. The cafes inside still serve Welsh cakes off a griddle and the bookshops have local poetry on tables by the door.

Then the M4 goes west. Two and a half hours later the road runs out at Pembrokeshire, and there is only one direction left: the cliff. The Pembrokeshire Coast Path is the United Kingdom’s only coastal national park, 186 miles of clifftop trail from St Dogmaels to Amroth, the full 300 kilometres of it walkable as one continuous route. The five-kilometre stretch around St Davids Head is the most cinematic — Carn Llidi rising inland, Whitesands Bay below, the Atlantic doing what the Atlantic does.

St Davids is the smallest city in Britain. Population 1,800, one cathedral, one ruined Bishop’s Palace, one cathedral close, and that is the entire town. Tenby, an hour south, is painted Georgian houses above a harbour, the medieval walls still standing, the lifeboat station still launching. The road back to Cardiff feels, by then, like a return from somewhere much further away than two hours.

Chapter 02 · the story

Yr Wyddfa is the highest ground in Wales — 1,085 metres of cloud and quartzite at the centre of Eryri. Around its foot the hillsides are the colour of roof tiles, because for two hundred years they were the world's roof.

Read the story Collapse

Yr Wyddfa is the Welsh name; the English call it Snowdon. The mountain is 1,085 metres, the highest summit in Wales and England, and on a clear day the view from the top reaches Ireland to the west and the Lake District to the north. The Llanberis Path climbs the gentler northern flank, nine miles return, four hours up, three hours down, alongside the cog rails of the Snowdon Mountain Railway that has been running since 1896 — the only public rack-and-pinion line in Britain. The summit cafe at Hafod Eryri serves a Bara Brith and a cup of tea at 1,085 metres above the sea.

The Welsh name for the whole region is Eryri, the place of eagles, and the park took that name back officially in 2023. Llanberis sits at the foot of the mountain, a village built of slate, set against a hillside hollowed out by slate. The Dinorwig quarry above the village ran from 1787 to 1969 and at its peak employed three thousand men. The Penrhyn quarry, twenty miles west, was at one point the largest slate quarry in the world. UNESCO inscribed the whole landscape — six quarries, the workers’ chapels, the narrow-gauge railways, the harbour at Porthmadog — as a World Heritage Site in 2021. The slate roofs of London, Hamburg, and Buenos Aires came from these hillsides.

Portmeirion is the strangeness on the other side of the day. Clough Williams-Ellis spent fifty years from 1925 building an Italianate fantasy village on a wooded peninsula above the estuary, painting it in pinks and yellows and pale greens, and filming The Prisoner there in 1967. The hills behind it are slate-grey and the village is bougainvillea-pink, and the two sit beside each other without apology.

Chapter 03 · the story

Conwy is a medieval town with the medieval town still around it — 1.3 kilometres of unbroken 13th-century wall, eight towers on a castle Edward I built to hold a country, and tucked into the harbour, the smallest house in Britain.

Read the story Collapse

Conwy is what a medieval walled town looks like when nobody pulled the walls down. The full circuit is 1.3 kilometres, twenty-one towers and three main gates, the wall-walk still complete around three sides of the town. Thirty minutes is the whole loop, with the slate roofs of the old town below on one side and the Conwy estuary on the other. The walls were finished in 1287, and they have stood there, quietly, ever since.

The castle is the reason the walls exist. Edward I built it between 1283 and 1289, one of four fortresses in his Iron Ring — Caernarfon, Beaumaris, Harlech, and Conwy — designed to hold Wales after the defeat of Llywelyn ap Gruffudd in 1282. The architect was Master James of St George, a Savoyard who built fourteen castles for Edward across Wales. Conwy has eight enormous towers grouped in two wards, the inner ward facing the river. UNESCO inscribed it, with Caernarfon and Beaumaris and Harlech, in 1986. From the battlements the view runs along the estuary all the way to Llandudno’s Victorian pier.

On the quay below the castle is a house painted oxblood red. It is 3.05 metres tall and 1.8 metres wide, two storeys, one fireplace, one bed upstairs, one chair downstairs. The Quay House — Britain’s smallest, still in the Guinness records — was lived in until 1900 by a fisherman who was over six feet tall and could not, by accounts, stand fully upright in either room. Entry is one pound. The custodian sits outside in a Welsh-flag waistcoat. The whole thing takes about ninety seconds to see, which feels, in a place this old, like a kind of punctuation.

Oct 2 · Day 8 · the last one

Last cawl at the Old Stables. Then the long flight east.

Final dinner at the Old Stables in Conwy — cawl (the Welsh lamb-and-leek stew that is the national dish) with crusty bread and a pint of Brains. Drive back east to Manchester for the morning flight to Heathrow, Cathay east to Hong Kong by Sunday afternoon. Seven nights — one inside Cardiff''s arcaded centre, two on the Pembrokeshire coastal path, three under Yr Wyddfa''s cloud-clad summit, one in the Conwy walls. The sound of Welsh being spoken in the village shop and the colour of slate at Llanberis quarry already half-remembered.
