The Nant Ffrancon Pass in Snowdonia, North Wales, is the long steady climb of the A5 road between Bethesda, Gwynedd, and Llyn Ogwen in Conwy. The summit at 312 metres (1,024 ft) is at Pont Wern-gof, about one-third of a mile beyond the eastern end of Llyn Ogwen. From here the road descends through Nant y Benglog to Capel Curig and through to Betws-y-Coed.
