Porth Ysgaden, Tudweiliog, Llŷn Peninsula, North Wales

Porth Ysgaden is something of a hidden gem that locals like to keep a secret! It is o
ne of the prettiest beaches on the Llŷn Peninsula but isn’t very well known. It won’t appear on many lists of “best beaches” as not many even know it is there. However, if you can find it then you will return time and time again!


If you mention Porth Ysgaden to someone who knows about it they will begin to swoon, and rightly so. Porth Ysgaden is flanked by rocky headlands which gradually slope to the sea. The result is a classic picture perfect horseshoe bay akin to somewhere in the Med on a sunny day. The sunken, sandy cove creates a sheltered bay perfect for little ones learning to swim or snorkel. The waters are popular with divers of all abilities and are great for shallow shore dives and beginners as the bay is sheltered from the Irish Sea. The northern headland is home to an old ruin which frames the wonderful sunsets that you get here.

The rock pools at Porth Ysgaden are amazing! The best spot for rockpooling is to the right of the beach. Head around the back of the bay keeping the gable end of the ruin to your left. Drop down over the headland and head down to the rocks below. At low tide, some of the rockpools are like plunge pools and home to a variety of species. Look out for squat lobster, jellyfish, starfish, anemone, hundreds of gobis and light bulb squirts. You can have hours of fun.

At a glance
  • The beach is a hidden gem.

  • Some of the best rockpooling for miles around is on the headland to the right of the beach.

  • Historically the beach was a landing point for supplies and exportation of goods from the surrounding farms and herring as it’s one of the most sheltered bays on the northern coast.  

  • The shallow waters are perfect for swimming and paddling.

  • If you are heading to the beach or the day, take time out to walk to Porth Gwylan or “Seagull Port”, approximately half a mile to the south. There is sheltered 'L' shaped bay consisting mostly of rocks with some soft sand at low tide. It’s a great spot to explore and is also good for rockpooling.

Beach info

Beach type

A sandy cove.

Take the B4417 South-West out of Morfa Nefyn through the village of Tudweiliog. Pass through the 30mph area and take a right at the sign for 'Penrallt Coastal Campsite'. After a short distance, where the main road goes sharp left, carry straight on into a narrow lane marked 'Beach / Camping'. Pass a house called 'Minafon'. The main road then curves to the right. You need to take the narrower lane straight on. As the tarmac lane goes sharp left, carry straight on into a narrow dirt-track which leads to the beach.


There are no facilities on the beach. The closest are at Cwt Tatws or in the village of Tudweiliog over a mile away.


Parking is free and it’s best to park at the top of the steep boat slip.


The beach, even though quite remote, is accessible due to the slipway onto the sand. However, it is steep so keep tight hold of handlebars and those less mobile should take care walking down.

Weather & tide

The deepest part of the bay is only 10m so it is best to dive at mid tide, close to high tide. The headlands are semi-submerged and the gullies flood providing points of interest.


It is sheltered and shallow.


Fishing off the rocks is excellent with the chance of hooking into Pollock, Flat Fish, Rockling, Wrasse or a decent sized Dog Fish.
