Porthgain to Abereiddi coastal walk

Enjoy some of Pembrokeshire’s finest coastal scenery while exploring its industrial past. The tiny fishing port of Porthgain once exported road stone all over the UK, while Abereiddi’s famous Blue Lagoon is a former slate quarry. Ynys Barri (or Barry Island), meanwhile, is home to a fantastic array of wildlife.

Start point

Porthgain, grid ref: SM816325 Postcode: SA62 5BP

Step 1

Walk along the south side of Porthgain Harbour below the brick hoppers. To reach the coast path, climb the steps next to a white building.

Step 2

Around a sharp left bend in the path, at the corner of a field, the tower above Abereiddi comes into view. Continue along the coast path through a section of dramatic high cliffs.

Step 3

Steps from here lead down to the tiny beach at Traeth Llyfn. Secluded and remote, the shore is completely covered at the highest tides. There can also be nasty rip currents so it's not recommended for swimming, just paddling and building sandcastles.

Step 4

The coast path continues over open grassland, skirting along the cliffs before zigzagging down towards Abereiddi beach. If you don't want to continue with the full circular walk, catch the Strumble Shuttle bus to Porthgain, St David's or Fishguard.

Step 5

Follow the yellow footpath arrows up a short slope and pick up a broad grassy path leading inland.

Step 6

Go over a stile, cut across the corner of the field and climb another stile by a pile of rocks. Follow the wide track east to Barry Island Farm.

Step 7

Take the track down to the road and cross to the other side, climbing some slate steps into a field.

Step 8

Walk straight across the field, go over a stile and along the hedge to a kissing gate. Follow this route back to Porthgain.
