Carn Hyddgen [Carn Gwilym]

Tucked away in the remote Pumlumon heartland, this grassy, peat-covered dome offers a sense of total isolation. Reached by long approaches from the Nant-y-moch reservoir, the summit plateau is a wild spot steeped in medieval history, overlooking the source of the River Rheidol and the sprawling Cambrian Mountains.

• •The name translates from Welsh as 'Cairn of the Stag's Brook', with 'hydd' meaning stag and 'gen' referring to the brook flowing through the valley below.
• •In June 1401, this hill was the site of Owain Glyndŵr's first major victory, where his small force of 120 men famously routed 1,500 English and Flemish soldiers by using the boggy terrain to their advantage.
• •The summit offers an earned view of the surrounding wilderness, including the nearby high point of Pumlumon Fawr and the distant, jagged silhouette of Cadair Idris to the north.
• •Attempting a direct line to this summit involves a tactical negotiation with some of the most persistent peat hags in Mid Wales, where returning with dry boots is considered a significant achievement.
