The Gwaun Valley (Cwm Gwaun) begins in Fishguard, where the namesake river runs into the sea. The Rough Guide describes as one of the great surprises of Pembrokeshire.
The steep sided valley was formed by the rushing waters from melting glaciers it is one of most important meltwater channels in Britain from the last Ice Age.
The Gwaun river rises to the east of Pontfaen in the Pembrokeshire Coast National Park. The valley is beautiful, rural, and forested with beech and hazel, ash and oak.
Bird watchers report sightings of pied flycatcher, wood warbler, redstarts, marsh tit, nut hatch and tree creeper.
The old pub at Pontfaen, the Dyffryn Arms. In the same family since 1840, it is a still working reminder of the country pubs of earlier generations.This is "Bessie’s Pub”. The namesake landlady herself may pour you a pint from a jug and hand it through a hole in the wall, with helpful hints about what to see in the area.
