Cwmorthin is a short trek away from the station at Tanygrisiau, but well worth a visit. There are several places to park at Tanygrisiau; there is a large car park as you drive towards the station, a small station car park, one by the popular Café and one at the quarry entrance. What’s more, they are all free. Tanygrisiau is also a station on the Ffestiniog Railway, near Blaenau Ffestiniog.
