TanygrisiauTanygrisiau, or more properly 'Tan y grisiau', is Welsh for "below the steps", referring to the stepped cliffs above the village. Tanygrisiau was famous for its slate mining, producing a high quality black slate that was used across the world. Tanygrisiau railway station is on the famous Ffestiniog Railway, a narrow gauge railway built to carry slate from the mines down to the sea at Porthmadog where it was shipped all around the world, mostly for use in roofing. The nearby Ffestiniog power station, the high Stwlan Dam and Llyn Ystradau, colloquially known as Tanygrisiau Reservoir, are part of a pumped storage hydroelectricity installation. Much nearer the railway station is a waterfall on the Afon Cwmorthin and below the falls, and powered by a different water source, is a very small hydro-electric power station. The closure of the slate mines during the late 1970s led to massive depopulation of the area from which it has recently begun to recover. Tanygrisiau has close links with the regiment of the Royal Welsh Fusiliers.
The village is a starting point for walks into the Moelwyns, especially if the intention is to climb Moelwyn itself. Care should be taken as there are numerous mine shafts in the area. As a result of the slate mining, when the Snowdonia National Park was created, Tanygrisiau, Blaenau Ffestiniog and Llan Ffestiniog were left outside, thus creating a doughnut-shaped area excluded from the National Park.
