Both Treffgarne and Wolfscastle are small villages midway between Haverfordwest and Fishguard. Treffgarne is quite spread out without an identifiable centre, unlike Wolfscastle. Treffgarne is better known for Treffgarne Gorge and the Dartmoor-like ‘tors’ that overlook it.

Treffgarne is notable for its beautiful deep wooded gorge through which the Western Cleddau tumbles alongside the railway line, the building of which defeated Brunel and practically bankrupted the Great Western Railway.

As both Treffgarne and Wolfscastle are on the main road linking Fishguard and Haverfordwest there are plenty of buses. Fishguard Ferry Port has twice daily ferry services to Rosslare in southern Ireland.

Treffgarne was the birthplace of Welsh hero Owain Glyndŵr. Nant Y Coy Mill is at the north end of the gorge, next to the cutting that was made for the A40, through the gorge. The age of the mill isn’t known but it was rebuilt in 1844 by the Evans family of Treffgarne Hall. The mill stayed in their possession for many years before it passed to the Higgons family of Scotton Manor and then into private hands some years later. The renovated mill wheel now turns once more.

Wolfscastle gets its name from the motte and bailey castle erected by the Normans on what is called the Landsker Line. This was a line of forts stretching from Roch near Newgale to Amroth and was a dividing line between The Normans and The Welsh in the north. Part of the Bailey is cut through by the A40 but some of it remains and have recently been cleared and opened to the public.
