Image of Esgair Irfon (Cist) by GLADMAN

The Irfon Valley from ‘The Devil’s Staircase’.... Esgair Irfon forms the rocky left hand flank, the cist situated approx midway. Incidentally the valley of the Nant-y-Fedw, Llanerch-yrfa (centre left, beyond the near treeline) is arguably the best starting point for those who may wish to visit Drygarn Fawr
