Mynydd Perfedd is a summit in the northern Glyderau. Unlike the range's better known and rockier peaks, Mynydd Perfedd is relatively broad and grassy. It is often visited on routes to the more exciting peaks of Elidir Fawr, Carnedd y Filiast or Foel Goch. The summit occupies a lovely position above Marchyln Mawr, a reservoir for the Dinowig Power Station.
