The Llanberis Pass (Welsh: Bwlch Llanberis; alternative English name, Pass of Llanberis) in Snowdonia carries the main road (A4086) from the south-east to Llanberis, over Pen-y-Pass, between the mountain ranges of the Glyderau and the Snowdon massif. At the bottom of the pass is the small village of Nant Peris.
