Pen-y-Pass is a mountain pass in Snowdonia, Gwynedd, North-West Wales. Situated at the high point of the Llanberis Pass at an altitude of 359 metres, the road was built in the 1830's to allow ore from the mines on Snowdon to be transported to Llanberis. The Llanberis pass road extends beyond Pen-y-Pass to join the Beddgeleret-to-Capel Curig road at the Pen-y-Gwryd Hotel. The climbing hotel was used as a base by Sir John Hunt, Baron Hunt and his team whilst training for successful 1953 expedition to Mount Everest.
