Porthgain: Coastal Walks and an Industrial Harbour

A stay in Porthgain can be planned around two themes: the history of the harbour and quarry, and the coastal walks. The village lies in the heart of Pembrokeshire Coast National Park. If you want to take both into account, you can compare the historic sites with the specific information on route length and walking time; this will help you see whether time or distance is the deciding factor in planning your day.

Harbour and Industrial History

Porthgain quarry opened in 1831. Construction of the harbour began around 1850 or 1851 to enable the export of slate quarried at Abereiddi and Porthgain. This sequence places the harbour within the local history of quarrying and transport.

Parts of the harbour are designated as Scheduled Monument PE382: these include the western breakwater, berths on the west side and storage hoppers. The red-brick hoppers were built from around 1905 to hold crushed granite until it was shipped. Thus, slate exports and the later-dated granite storage hoppers stand side by side at the harbour as distinct stages in its industrial history.

Porthgain’s Pilot House is a Grade II listed building. The Sloop Inn in the village dates from 1743. The row of houses called The Row on the west side of the village was recently reroofed with Abereiddi slate salvaged from a cargo that sank in the 19th century. In 1991, remains of brick kilns were visible on the quarry site.

Porthgain is not just a historic harbour: several fishing boats, leisure boats and a rowing club still use it. The rowing club is based in the former Ty Mawr brickworks.

Coastal Walks and Planning

The Pembrokeshire Coast Path runs between St David’s and Fishguard, with Porthgain on the route. The coastal walk from Porthgain to Abereiddi starts in the village. The Porthgain/Abereiddi walk is 3.6 miles (5.8 km) long and takes two hours. One notable viewpoint on this route is Traeth Llyfn beach.

Porthgain Clifftop is an adventure walk of 3.6 to 4.4 miles (5.8 to 7.1 km), combining coastal views with industrial heritage. The route follows the line of a former tramway, with some railway sleepers visible at the surface. A tramway connected Abereiddi’s main quarry with the hoppers above Porthgain harbour. The walks offer different planning reference points: Porthgain/Abereiddi gives a specific duration, while Porthgain Clifftop gives a distance range. This lets you choose according to your time frame or preferred distance.

The Porthgain Quarry Easy Access route leads from the car park to the cliffs and along the old incline to the granite quarry near Porthgain. From this route, you can enjoy views of St David’s Head and Strumble Head. Porthgain Clifftop is served by the wheelchair-accessible Strumble Shuttle. If you plan to use the shuttle, check the timetable in advance.
