Pant Glas (Welsh for Green Hollow - in Welsh, as in other Celtic languages, "glas" may mean both 'green' and 'blue') is a hamlet on the A487 road in Gwynedd, Wales. Historically in Caernarfonshire, it is located approximately 10 miles (16 km) south of Caernarfon, 9 miles (14 km) miles north-west of Porthmadog, and 10 miles (16 km) north-east of Pwllheli. Nearby is the former Pant Glas railway station, which was closed as well as the Carnarvonshire Railway in 1964.
