Walk Route Description

The Pembrokeshire Coast National Park despite its small size has plenty to offer walkers. The coastline is varied and this particular walk takes in one of the more rugged sections. Nowhere is this route strenuous but it does offer the opportunity to feel close to the sea and rocks. In addition there is a good chance you will see some interesting birds together with the opportunity to see some seals.

The start is in the small car park at Porth Clais (grid ref. SM741241). During the peak months there is a small charge. From the car park walk towards the small harbour and keep on the right hand side taking the signed coast path.

The onward route is straightforward staying close to the top of the cliffs for the section through to St Justinian's where there is a lifeboat station. The path is easy to follow and there are only a few ups and downs. The views are on the seaward side with interesting cliffs complete with caves and arches. Quite soon after leaving Porth Clais you can see the rocks of Ramsey Island, which lies just over a mile off shore. This sparsely inhabited island can be visited and looks as though it provides some excellent walks.

Like many coastal walks there are a few sections where a slip could end in personal disaster but assuming you have safely negotiated these dangers you will arrive at St Justinian's where the corrugated lifeboat station contains an immaculately maintained vessel. Admission to the station is by donation. Ahead, further along the coast lie two fine looking hills, one with a good ridge. These can easily be included by extending the walk.

Take the lane heading inland and follow it past Rhosson farm. To your right is a reedy pool - Pwll Trefeiddan - and after this turn right at a junction. This lane leads down to Clegyr-Boia and on past Rhos y-cribed farm to reach the car park at Porth Clais.

Pembrokeshire Coast Walking

The Pembrokeshire Coast National Park is Britain's only truly coastal national park. Rimmed by a spectacular waterscape of rugged cliffs, sandy beaches and wooded estuaries, the land rises to wild inland hills. This environment is a place of sanctuary for wildlife who share the landscape that has been shaped by many people over the centuries. Tombs and castles, crosses and cottages, quarries and quays are all reminders of man's endeavours, which remains a working landscape. Inland the Preseli Hills offer excellent walking across the moorland ridge. More Information
