Reading history stays on this device. My road watch requires a separate selection; opening it does not subscribe this ride.
Distance and riding time are measured on the routed road. Check local closures and conditions before you ride.
A 246 km round trip from Beaumaris - roughly 4 h 26 in the saddle. On the way it passes Castles and Town Walls of King Edward in G, Gorseddau and Prince of Wales Slate Quarri, Bryneglwys Slate Quarry and back through Gorseddau and Prince of Wales Slate Quarri. It was put together for the scenery rather than the shortest line.

Waypoint introductions and full write-ups
1. Beaumaris Castle
Beaumaris is often called the most perfect castle never finished. Edward I began it in 1295 on the shore of Anglesey, at the northern entrance to the Menai Strait, as the last of his great chain of fortresses built to hold down Wales after his conquest. His architect, Master James of St George, designed it as a perfectly symmetrical concentric castle: an inner ring of high walls and towers, an outer ring of lower walls, and a moat linked to the sea so that supply ships could sail up to a dock at the gate. Money ran out, the Scottish wars took priority, and the towers never reached their planned height. Even so, it is a masterpiece of military design, and with the castles of Conwy, Caernarfon and Harlech it is listed by UNESCO.

Planning note
Beaumaris Castle is where the day begins. Next is Castles and Town Walls of King Edward in G.
2. Castles and Town Walls of King Edward in G
Edward I built Caernarfon to be unmistakable. Begun in 1283, after his conquest of Wales, the castle rises beside the Menai Strait with polygonal towers and bands of coloured stone that echo, it is said, the walls of Constantinople, a deliberate reference to imperial power. The King wanted a seat of government as well as a fortress, and the town walls were built to enclose a planted English borough, so the whole thing was an act of colonisation in stone. UNESCO listed Edward's castles and town walls in Gwynedd in 1986, together with Conwy, Harlech and Beaumaris, and Caernarfon is the grandest of them.

Planning note
Castles and Town Walls of King Edward in G comes up 35 km in. Next is Gorseddau and Prince of Wales Slate Quarri.
3. Gorseddau and Prince of Wales Slate Quarri
High above Porthmadog, in the empty upland between Cwm Pennant and Cwmystradllyn, two abandoned slate quarries sit like ruined castles on the hillside. Gorseddau and the Prince of Wales quarry are part of the Slate Landscape of Northwest Wales, which UNESCO listed in 2021, and they tell a story of big hopes and quick failure. Gorseddau in particular was developed in the 1850s with money and ambition, a tramway and a grand multi-storey mill at Ynys-y-Pandy whose roofless stone shell still looks like an abbey. The slate turned out to be poor, and within a couple of decades the whole enterprise had wound down.

Planning note
71 km in you reach Gorseddau and Prince of Wales Slate Quarri. Next is Bryneglwys Slate Quarry.
4. Bryneglwys Slate Quarry
High above the village of Abergynolwyn, in a side valley where the sheep outnumber everyone, the spoil heaps of Bryneglwys tell you that this quiet corner of southern Snowdonia was once an industrial place. Slate was cut here through the second half of the nineteenth century and into the twentieth, and the whole reason the little Talyllyn Railway exists is to carry it down the valley to the coast at Tywyn. The quarry finally closed just after the Second World War, and the railway, which should have died with it, was taken over by volunteers in 1951 and became the first preserved railway in the world. You can still walk up from the old incline at Nant Gwernol into the quarry workings, past roofless barracks and wheel pits, with streams running through all of it.
