Porth Dafarch, Treaddur Bay, Anglesey, North Wales

Porth Dafarch,
nestled into the cliffs and backed by a sea wall, often provides a sheltered spot for families, canoeists and kayakers. With ample rock pools and rocky rambles on offer, children love it. It’s also a well-known haven for swimmers. Being only about a 100 metres wide, Porth Dafarch is smaller and more secluded than the nearby Trearddur Bay. Located in a designated Area of Outstanding Natural Beauty, this lovely little spot, popular with fisherman and watersports enthusiasts, is owned by the National Trust and was voted No. 10 in The Daily Post’s ‘Best Beaches in North Wales’ list!

Porth Dafarch offers some amazing snorkelling opportunities in its crystal clear waters, and the area is also famous for its scuba diving, with the 1886 wreck of the steamer, Missouri, situated around half a mile offshore. With its mixture of sand, rocks and shingle, it’s a great place for a family picnic. There are lovely walks along the coastal path in both directions, with wonderful views back across the bay.


Situated on the Western coast of Holy Island, it makes up part of a series of sheltered coves here, opening out Southwest into the Irish Sea. You’ll find it about half a mile to the West of Trearddur Bay, on Lon Isallt/the South Stack/Porth Dafarch Road. Porth Dafarch offers more than just sandcastles and sandals, and is definitely worth a visit! Close enough to Trearddur to be able to pop there for provisions, but far enough away to feel more secluded - this beautiful bay is popular with holidaymakers and locals alike.

Top tips
Flora & Fauna
Weather & tide

At its best with a south-west swell and the wind is from the east. It isn’t the most consistent break but good fun when the conditions are right. The best waves are found during the winter.


It’s a popular beach for windsurfing.


Porth Dafarch provides some great fishing. It’s popular off the beach, as well as from either side -  on the cliff ledges. According to experts, it’s best for fishing during neap tides - however, it can be a little snaggy! Coalfish are abundant during February into early March, and night tides are good for conger and huss, especially when it begins to calm after a storm.


North Wales Coasteering have two main routes, both start & finish at Porth Dafarch.
