It flows in a southerly direction from its source near Hay-on-Wye, through Herefordshire’s famous Golden Valley before joining the Monnow below Pontrilas. Despite this being genuine small stream fishing where a short rod is essential, thigh or chest waders are required to negotiate your way through deceptively deep pools. Wild trout are the main inhabitants of the Dore although grayling are also present (This is where they were introduced to the system in the 1860s), making this beat one of the few in the whole of the Wye catchment where this species can be caught in a small stream.
