The Fox verdict
Come for the walking; stay for the mill's story
Trefin brings together the Coast Path, the small cove at Aberfelin and the memory of a mill that inspired a celebrated Welsh-language poem.
The walking is the main event, with Porthgain and Abereiddi in one direction and Abercastle and Carreg Samson in the other. In the village, The Ship Inn offers pub food, cask ales and outdoor seating with countryside views.

The village story
Trefin Village Guide
A coast-path village shaped by an old inn, a lost mill and the poem that kept its memory alive.
An inn and a village above the sea
The Ship Inn stands in the heart of Trefin, a short walk from the Pembrokeshire Coast Path. Inside, the historic pub has a bar and dining space; outside, seating looks over the countryside. It serves hearty pub food, cask ales and local beers, and offers rooms for visitors staying in the village.
Trefin is a linear village set back from the sea. Its street pattern preserves traces of the medieval settlement associated with the Bishops of St Davids, and remnants of the old strip fields survive in the surrounding landscape.
The bus and Melin Trefin
The seasonal Strumble Shuttle coastal bus connects Trefin with Porthgain, St Davids, Mathry, Strumble Head and Fishguard. Walkers can also follow the Coast Path out of the village in either direction.
At Aberfelin, the rocky cove sits below the ruins of a water mill. Bishops of St Davids once owned the mill, where wheat and barley were ground for five centuries until it closed in 1918. The ruin inspired Archdruid Crwys's poem "Melin Trefin", and old mill leats are still visible across the road.
The Coast Path in both directions
Singer Cerys Matthews lived in Trefin when she was young. Welsh-language poet Edgar Phillips was born here and later became Archdruid of Wales.
The walking is the main event. The Coast Path runs past Trefin, with the historic slate-and-stone harbour and the flooded slate quarry at Abereiddi to the west. East toward Abercastle is Carreg Samson, a Neolithic burial chamber whose capstone rests on three uprights. Local legend says Saint Samson lifted the stone into place with his little finger.
Church, chapels and what remains
St Rhian's Church stands at Llanrhian. Trefin's old Methodist and Baptist chapel buildings recall the village's religious history, while the seasonal Strumble Shuttle provides a coastal bus connection toward St Davids and Fishguard.
The mill and quarrying have ceased, but their traces remain in Trefin's landscape and in "Melin Trefin".
