Waypoint introductions and full write-ups
1. Aberystwyth
Aberystwyth is Welsh to the core and slightly eccentric with it. The town sits where the rivers Rheidol and Ystwyth meet Cardigan Bay, with a sweeping Victorian seafront, a pier, a ruined thirteenth century castle left by Edward I, and a university that was founded in 1872 as the first in Wales. The university's old building on the seafront, a Gothic fantasy that began life as a hotel, tells you something about the ambitions of the founders, who raised the money from small donations from ordinary Welsh people. The National Library of Wales stands on a hill above the town and holds some of the country's greatest manuscripts.

Planning note
Aberystwyth is where the day begins. Next is Gorseddau and Prince of Wales Slate Quarri.
2. 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
Gorseddau and Prince of Wales Slate Quarri comes up about 103 km into the recorded legs. Next is Ffestiniog: its Slate Mines and Quarries.
3. 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.

Planning note
At least about 132 km into the recorded legs you reach Ffestiniog: its Slate Mines and Quarries. Next is Nantlle Valley Slate Quarry Landscape.
4. Nantlle Valley Slate Quarry Landscape
Look at the Nantlle valley from the road and you see a green bowl with a ragged grey edge, as if someone had bitten the mountain. It is a place where the quarrying went down instead of along. The pits here are enormous, cut deep below the level of the lakes, with sheer sides, and the biggest of them, the Dorothea, became a flooded hole of cold green water. On the skyline, tips of waste slate lean against each other like broken plates. This is part of the slate landscape of north-west Wales that UNESCO listed in 2021, and the quarries here are among the oldest in the area, producing roofing slate from the eighteenth century and earlier.

Planning note
Nantlle Valley Slate Quarry Landscape, 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.
