Pumlumon Arwystli (741 m/ 2,431 ft) and Cwm Gwerin
To hugely extend the 'wildness experience' of the Pumlumon range, we can add another peak, Pumlumon Arwystli, then descend via the remote, beautiful 'hidden' valley of Cwm Gwerin; providing an unforgettable but challenging adventure. This is not to be undertaken lightly, involving difficult terrain in the two cwms, such as boulder fields, marshy tussocks and stream crossings, with few real paths.
