Plynlimon

Plynlimon (anglicised from Pumlumon in Welsh, meaning "five peaks") is the highest point of the Cambrian Mountains in Wales, and the highest point in Mid Wales. It is a massif that dominates the countryside of northern Ceredigion.

The highest point of the massif itself is Pen Pumlumon Fawr at 752 metres (2,467 ft). Its other important peaks are Pen Pumlumon Arwystli, Y Garn, Pen Pumlumon Llygad-bychan and Pumlumon Fach.

The longest river in Britain, the River Severn, has its source on the mountain, as do the rivers Wye and Rheidol.

Folklore says there is a sleeping giant in Plynlimon.

Habitat

The Pumlumon area is the largest watershed in Wales and is the source of the rivers Wye, Severn and Rheidol. Since 2007 the Wildlife Trusts of Wales have been working to improve the habitat as a "living landscape" project. This watershed area has been affected by loss of biodiversity, erosion of the peaty soils' structure, and accelerated drainage. Some believe the drainage issues have contributed significantly to flooding in areas some distance downstream, though this cannot be clearly proved.
