Wales, from Pembrokeshire to Eryri
Medieval castles, a coast of cliffs and beaches, mountains where people speak Welsh. Eight days from Cardiff to Conwy, through the Brecon Beacons, Pembrokeshire, Cardigan Bay and Eryri.
Castles, a coast and mountains
This trip mostly follows the Welsh coast, from Cardiff to Conwy, with two stretches through the mountains. In the south, one castle follows another: Cardiff’s own, Castell Coch in the woods, then Caerphilly and its lakes. The road then reaches Bannau Brycheiniog, the Brecon Beacons, hills covered in moorland. From the Pont ar Daf car park, a path leads up Pen y Fan, 886 metres, the highest point in the south of the country.
West of Swansea, the Gower peninsula ends at Rhossili Bay and the islet of Worm’s Head, which you can reach at low tide. Further on, Pembrokeshire is home to the only coastal national park in the UK. You reach Barafundle Bay on foot from Stackpole Quay. St Davids, the smallest city in the UK by population, grew up around its cathedral.
In the north, Cardigan Bay leads to Aberaeron, Aberystwyth, Harlech and Portmeirion. Then come the mountains of Eryri, Snowdonia. The Llanberis Pass climbs between cliffs up to Pen-y-Pass, where the paths to Yr Wyddfa, Snowdon, set off: 1,085 metres, the highest summit in the British Isles outside Scotland. A rack railway goes to the summit from Llanberis. After the pass, the road goes through Betws-y-Coed and follows the Conwy valley down to the sea.

The castles of Edward I
Harlech Castle looks down on the dunes from its rock. In the 13th century, the sea came almost to its foot, and the garrison could be supplied by boat. Edward I, King of England, had it built between 1283 and 1289. During the Wars of the Roses, Lancastrian supporters held it for seven years, until 1468. The siege is said to have inspired the song “Men of Harlech”.
Harlech is one of the great castles Edward I built after the death, in 1282, of Llywelyn ap Gruffudd, the last independent Prince of Wales. Together with Conwy, Caernarfon and Beaumaris, it has been a UNESCO World Heritage Site since 1986. At Caernarfon, Prince Charles was invested as Prince of Wales in 1969.
Other castles are older. Caerphilly, begun in 1268, is the second-largest in the UK. One of its towers leans. Henry Tudor, the future Henry VII, was born in 1457 at Pembroke Castle.
In the north-west, you hear Welsh every day.
Welsh and its legends
Welsh is a Celtic language, a cousin of Breton, and an official language of the country. Road signs are bilingual: Caerdydd for Cardiff, Tyddewi for St Davids. In the 2021 census, 17.8% of residents said they spoke it, and 64.4% in Gwynedd, around Caernarfon. In the north-west, you hear Welsh every day.
There are legends everywhere. In Beddgelert, a grave is said to be that of Gelert, Llywelyn the Great’s dog. The prince supposedly killed him, thinking he had attacked his son. The dog had saved the boy from a wolf. The grave was really laid out in the 18th century by an innkeeper. According to tradition, a woman who rose out of Llyn y Fan Fach, a lake in Bannau Brycheiniog, married a young local man, then went back into the lake after he had struck her three times.

Devil’s Bridge (Pontarfynach)
Three bridges, one above the other, span the Mynach gorge: the lowest, of uncertain date, then those of 1753 and 1901. Legend has it that the devil built the first one and an old woman tricked him with her dog. Right next to it, the river drops about 90 metres in a series of falls.

The Welsh table
The national dish is cawl, a lamb and leek stew. At teatime, there are Welsh cakes, small round cakes cooked on a griddle, and bara brith, a loaf made with dried fruit soaked in tea.
On the south coast, people eat bara lawr, or laverbread, a seaweed purée, with cockles and bacon. The Penderyn distillery, opened in 2000, brought Welsh whisky back to life.
