Some of the most dramatic mountain scenery in Ceredigion is found in the vicinity of Cwmystwyth, a former lead/silver mining village which offers this superb circular adventure. Although not particularly long, this walk is challenging in its steep ascents, rough going underfoot, and the necessity for careful route-finding. However, the rewards are magnificent, with rapidly changing scenery and countryside of immense character. Here we experience first the steep-sided and craggy Ystwyth valley, followed by an awesome taste of the great ‘green desert of Wales’, with the conical hump of Domen Milwyn providing a focus.
