This excellent Pembrokeshire Walk starts from the harbour village of Porthgain and then crosses Ynys Barry to Abereiddi Bay. The route then returns to the start following the Pembrokeshire Coast Path. The coastal section of the walk passes the Blue Lagoon, the sands of Traeth Llfyn and a scenic section of coast before returning to the start.
The start is the car park at Porthgain (grid ref. SM815321). Leave the car park and follow the road you used to reach Porthgain. Continue up the road for 800 metres. You will pass a footpath sign and gate on the left. A short way beyond this bear right down a tarmac lane. Continue along this lane and walk past the Ynys Barry Holiday Cottage complex. Join a track and follow this for 800 metres where the field boundary turns left at 45 degrees. Initially follow the wall and where the wall turns left again cut across the field to a gate. Once through the gate follow a track across the hillside towards the sea passing to the right of a white painted toilet block.
Beyond the toilets turn right and join the Pembrokeshire Coast Path with the sea on your left. You pass the entrance sign to the National Trust Ynys Barri with an information board down a side path on your left. Stay on the main path, pass through a gate and immediately take the right-hand fork. The rising path soon offers a grandstand view of the Blue Lagoon below on your left, which is a flooded former quarry. Do be careful here especially with children as there is steep drop off the path!
The coast path then offers a beautiful cliff top walk. You first pass Traeth Llfyn (beach) before cutting across a small headland to continue along a clifftop path. The path is well-signed with the National Trail Acorn symbol so you can relax and enjoy the stunning coastal scenery. The walk finishes with a descent to the quayside. Continue ahead back to the carpark.

Further Information
Pembrokeshire Coast Walking
Walking in 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.
