Porth YsgoAberdaron, Llŷn Peninsula

Porth Ysgo on the Llŷn Peninsula, North Wales

Porth Ysgo is a secluded beach a few miles from the fishing village of Aberdaron. This special cove of golden sand is backed by grassy cliffs and sparkling waterfalls.

Porth Ysgo is a sandy inlet that sits between the village of Aberdaron to the west and the expansive Hell’s Mouth to the east. It forms part of the Llŷn coastal path, offering spectacular coastal walks with incredible views. Accessed via 100 or so steps, the beach is less accessible than some, but is worth making the effort to visit with its pretty waterfalls and rock formations, renowned with climbers. Some consider it to be the most beautiful beach on the Llŷn Peninsula.


Porth Ysgo is only small but has a lot to offer. It lies within the ’Pen Llŷn a’r Sarnau’ Special Area of Conservation and is an Area of Outstanding Natural Beauty. The beach is great for bouldering, bird watching, fishing and is in an area popular with walkers and cyclists. It is also a lovely place to just relax. When descending the steps, look to the right just before you get to the beach. The stunning Pistyll y Gaseg waterfall flows into the hollow. A great thing about visiting the beach during a spell of wet weather is that the waterfall becomes spectacular, making Porth Ysgo a great place to visit at any time of the year! Remains of the working of the Nant Gadwen Manganese Mine can be seen on the path down to the beach.

The area itself was hugely significant in the extraction of manganese ore, used for strengthening steel during both World Wars. There are a number of above ground works still visible and of historical interest.
