A massive massif, Pumlumon’s (or the anglicised Plynlimon) high point is Pen Pumlumon Fawr. From the slopes below this summit the Rivers Wye, Rheidol, and Britain’s longest, the Severn, begin their journeys to the sea. It’s a high and wild landscape, rich in bird life and a genuine escape for the solitude-seeking hillwalker.

This is a beautiful area and less busy than the more popular peaks of Wales. It's a stunning, remote landscape of lakes and barren hills that are still high enough to be in the Nuttall category.
