Distance and timing basis
Ordered leg totals agree within rounding. Stop distances are approximate sums of rounded legs. Stops, delays, approach and any separate return travel add time. Basis: producer-declared routed record.
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.
Scenic road chapters
Snowdonia Llanberis Pass
19 km through ground somebody thought worth listing. The road passes it rather than bypassing it — speed drops and stays down. Park rather than crawl through.

Snowdonia Llanberis Pass
For about 29 km this is Snowdonia Llanberis Pass, a road with a name of its own and a reason for it. Expect company on a summer weekend. Early is better than fast.

Waypoint introductions and full write-ups
1. 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.

Planning note
Bryneglwys Slate Quarry is where the day begins. Next is Harlech Castle.
2. Harlech Castle
When Edward I built his castles in Wales, he was not interested in subtlety. Harlech, raised between 1283 and 1289 by the master mason James of St George, sits on a rocky crag above the dunes of Cardigan Bay, with concentric walls, massive gatehouse and round towers that still look ready for a siege. It is one of the castles of Edward I in Gwynedd listed by UNESCO, together with Caernarfon, Conwy and Beaumaris. The sea once came almost to the foot of the rock, and a staircase down the cliff allowed the garrison to be supplied by boat; the coast has since moved, and now there is a broad plain of dunes and a golf course between the castle and the water.

Planning note
Harlech Castle comes up about 64 km into the recorded legs. 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
about 88 km into the recorded legs you reach Gorseddau and Prince of Wales Slate Quarri. Next is Ffestiniog: its Slate Mines and Quarries.
4. Ffestiniog: its Slate Mines and Quarries
Blaenau Ffestiniog is a town built on, among and out of slate. Great grey tips of waste rock tumble down the mountainsides around it, old quarry inclines climb the slopes, and the houses, chapels and walls are all made of the same dark stone. For a century and more this was one of the slate capitals of the world, roofing houses from London to Melbourne, and since 2021 it has been part of the UNESCO-listed Slate Landscape of Northwest Wales. It is not pretty in the conventional sense, but it is magnificent, and on a day of sun breaking through rain clouds it can look like a lunar landscape lit by spotlights.

Ffestiniog: its Slate Mines and Quarries, about halfway. Next is The Slate Landscape of Northwest Wales.
5. The Slate Landscape of Northwest Wales
Llanberis sits at the foot of Snowdon, Yr Wyddfa in Welsh, beside the lake of Llyn Padarn, and across the water a whole mountainside has been carved into giant terraces. This is the Dinorwic quarry, once one of the largest slate quarries in the world, where thousands of men worked until it closed in 1969, splitting slate for roofs across Britain and beyond. The galleries climb the mountain in steps, with inclines, ruined buildings and waste heaps everywhere, a landscape both scarred and strangely beautiful. In 2021, UNESCO inscribed the Slate Landscape of Northwest Wales, recognising the quarries, villages, railways and harbours that made this region the slate capital of the world.
