    Tips

    January 1, 2026

    Hiking

    The remains of the quarry are huge, both spoil heaps and derelict building. There are also some huge cavern openings that are to be avoided if going on to climb the Moelwyns from here. The workings were underground rather than open cast like some of the Blaenau Festiniog or Dinorwic quarries.

    Hiking

    The pass take you through Rhosydd's abandon mining quarters and work area. Where deteriorate machinery and mine entrance can still be seen. Beyond this the pass takes you above the mine entrance between large slate stakes to the hills of Moel-yr-hydd, Moelwyn Mawr and Bach
