If you are travelling from the direction of Llanberis turn left by the Glyntwrog Inn (shortly after reaching the 30 mph sign for Llanrug) and carry on for about 3/4 of a mile towards Ceunant/Waunfawr, when you reach Trevor Terrace on your left carry on a little further until you come to a white cottage on your right (Ty’n Ffynnon). Turn down by the gable end of the cottage and carry on for about 300 yards and you’ll find Hen Dy on your left.

If you are coming from the direction of Caernarfon drive through Llanrug until you see Glyntwrog Inn on your right, just before you leave the village. Turn up by the Glyntwrog and follow directions as above.
