Pen Pumlumon-Arwystli’s cairns overlook Cwm Gwerin, arguably one of the wildest in all Wales. Perhaps the wildest? The twin monuments of Carn Hyddgen can be seen in shadow, top right. Banc Lluest Newydd resides upon the sunlit hill approx centre. TMA’ers ascending the mountain via Pen Pumlumon-Fawr may well find the valley a good descent route back to Maes Nant.
