Beautiful old pub! Stopped here after a hike & it was fascinating inside, plenty of locals, of course a lot of tourists (as I was!) But I'd love to come back here sometime & go there for the evening, it just looks like it gets a bit loose!

Porthgain, a small coastal village in Pembrokeshire, became an industrial hub in the 19th and early 20th centuries. The quarrying activities in Porthgain primarily focused on slate and later on roadstone. The harbour, constructed in 1851, was essential for exporting slate from nearby quarries. Initially, slate was transported to the harbour by horse-drawn tramways and later by steam-powered machinery. By the late 19th century, the industry expanded to include brickmaking using slate waste. The demand for roadstone led to the development of steam-powered crushers and large storage hoppers, which are still visible today. Despite its industrial success, the Great Depression in the inter-war period led to a decline in trade, and by 1931, the quarrying activities had ceased. Today, Porthgain is a conservation area, preserving its rich industrial heritage and attracting visitors to its historical sites and scenic beauty

Porthgain is known for its picturesque harbour and rich industrial history. The village was once a bustling industrial port in the early 1900s, primarily involved in the export of slate, bricks, and crushed roadstone. Quarry History: • Slate Quarrying: Slate was the primary industry in Porthgain from around 1850 to 1910. The slate was quarried from nearby locations like Abereiddi and Trwynllwyd and transported to Porthgain via a tramway. • Brickmaking: From 1889 to 1912, bricks were manufactured using waste from the slate operations. The large brick hoppers that dominate the harbour today were used to store crushed dolerite before shipment. • Roadstone Production: After the decline of the slate industry, Porthgain turned to producing crushed roadstone from 1889 until 1931. Today, Porthgain is a conservation area, attracting visitors with its historical charm, scenic views, and local seafood. The harbour remains active, primarily serving local fishermen and recreational boaters.

Remnants from a time gone by then ships used to be loaded with quarried materials via the structures that still remain.

Yes, the area is well-suited for circular hikes. Many trails combine sections of the Pembrokeshire Coast Path with inland paths, allowing you to start and end in the same place without retracing your steps. A great example is the Porthgain Harbour to Blue Lagoon at Abereiddy loop, which offers a fantastic coastal experience.
The trails are quite varied, but most are manageable for regular walkers. Out of more than 45 routes in the area, the majority are rated as easy, with a smaller number of moderate and difficult options. You'll mostly find well-trodden coastal paths, which can have some steep sections and steps, but the stunning sea views are a worthy reward.
The Pembrokeshire Coast Path is generally very dog-friendly, and many hikers explore the area with their four-legged friends. However, always be mindful of livestock in fields and keep your dog on a lead, especially near cliff edges. Some beaches may have seasonal restrictions, so it's wise to check local signage.
Absolutely. Many of the easier coastal walks are suitable for families with older children. The Porthgain, Ynys Barry walk is a shorter, easy option that still provides a great taste of the coastline and local history without being too strenuous for younger walkers.
The hiking routes around Llanrhian are highly regarded by the komoot community, with an average rating of 4.8 out of 5 stars. Hikers frequently praise the spectacular coastal scenery, the well-maintained paths, and the unique blend of natural beauty with industrial heritage, like the ruins at Porthgain.
Parking is available in the nearby villages of Porthgain and Abereiddi, which are both excellent starting points for hikes along the coast path. These are popular spots, so arriving early is recommended, especially during peak season. Some lay-bys and smaller car parks can also be found along the lanes leading to the coast.
Yes, the area is rich in history. The walk between Porthgain and Abereiddi is a prime example, featuring the impressive brick hoppers and harbour ruins from Porthgain's time as an industrial port. The famous Blue Lagoon at Abereiddi is itself a flooded former slate quarry. You'll find remnants of the past woven into many of the coastal trails.
Yes, the Pembrokeshire coast is served by local bus services, including the 'Strumble Shuttle' and 'Puffin Shuttle' which are specifically designed to help walkers access different sections of the coast path. These services allow you to walk a linear route and catch a bus back to your starting point. It's best to check the latest timetables online before you go.
The harbour village of Porthgain is a popular spot for post-hike refreshments, offering a pub and a cafe right by the water. The nearby village of Trefin also has a pub, making it a good end-point for a walk, such as the Porthgain to Trefin route.
You can hike here year-round, but late spring and summer offer the best weather and the longest daylight hours. Spring is particularly beautiful with coastal wildflowers in full bloom. Autumn can also be a wonderful time with fewer crowds, though you should be prepared for more unpredictable weather.
The coastline itself is the main attraction. A walk towards Trefin, like the Trefin – Pembrokeshire Coast National Park trail, will take you past secluded coves and dramatic cliffs. For panoramic views, a hike up Carn Llidi near Whitesands Bay is highly recommended. You can also spot a variety of seabirds and potentially seals along the coast.
