Porth Rhwydau, Holyhead, Anglesey, North Wales

Porth Rhwydau, a sandy little cove tucked away on the far side of the Holy Island, is just perfect for the wild at heart! Only revealed on low tides, the tiny beach all but disappears at high tide, so remember to check timings before setting off.

Somewhat off the beaten track, Porth Rhwydau is not a beach for faint-hearted, but if you do manage to get there you’ll be so glad you did! A magical spot for a private picnic, with lots of caves and interesting geological features to investigate too. It really is a special little part of Holy Island.


Sandy at mid to low tide, but underwater thereafter. If you time it right it makes a fascinating destination. Its attraction lies not in its facilities or bustle, but rather in its seclusion and secret nature. Those who visit never forget it!

You can only access to Porth Rhwydau on foot, via the Anglesey coastal path. It also requires a bit of a climb/scramble down the rocks at the end of the beach on the eastern side. The descent isn’t too difficult, but you’ll need to take it carefully and slowly, and do take some time to work out the best route down! Definitely not suitable for pushchairs or those with limited mobility. Keep a tight hold of younger children.

From Porth Dafarch, turn left down the slipway, then go round the back of the beach below the road, bear left, and up a step, keeping on the path that leads round the ledge. Cross a large stile (by the caravan park) and carry on over the hill, following the coast. Next, cross a sleeper bridge, then a stone stile, and head down the steps that are around the back of Copper Mine Creek. Turn right, through a field towards a kissing gate. Stay on to the path that runs parallel to the coastline, onward to another kissing gate. Lastly, join the track and, bearing left, follow the coast past the island marked Dinas. Keep on this path until you reach Porth Ruffydd. The coastal path skirts around the back, but you’ll need to take the cliff-side route down from here.

Dog restrictions

Dogs are allowed but be aware, many will find the scramble down difficult!

Top tips
Flora & Fauna
Weather & tide

All the little bays around here provide some smashing fishing opportunities - both off the beaches, as well as from the nearby headland and cliff ledges - but remember to take care if carrying a lot of equipment! According to experts, this coast is best for fishing during neap tides - however, it can be a little sea-weedy and 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. Mackerel are a common catch during the summer months.
