Carreg Wen beach, Borth y Gest, Llŷn Peninsula

Carreg Wen and Samson’s Bay are two idyllic, golden sandy bays that back on to Porthmadog golf course.

Both bays form part of the extensive golden sands that make up Tremadog Bay and the banks of the Mawddach Estuary. They have a “castaway” feel to them and on a sunny day, you would think you were in a tropical island paradise.


The beaches offer beautiful scenery and a feeling of remoteness even in the height of summer. Both beaches are most easily accessed by walking around the headland on the sand from Borth y Gest at low tide.

The larger of the two is Samson’s Bay, at 600m long and backed by a seawall of boulders. The beach closer to Borth y Gest is Carreg Wen, which is about 300m long with stunning sand dunes and rocky outcrops.  Both beaches are great to walk to along the coastal path from Borth y Gest and make great “picnic destination” beaches. They are backed by the rough of Porthmadog Golf Course. And the surrounding scenery and views across the estuary are breathtaking.

  • They have a unique, remote feel of a tropical island hideaway and spectacular scenery.

Beach info

Beach Type



There are no facilities on the beaches themselves. The nearest ones are in the village of Borth y Gest.



The closest place to park your car is the free car park adjacent to the beach in the centre of the village of Borth y Gest. In the summer months, when this fills up, you are able to park on the side roads around the village, subject to restrictions. The school has a small car park opposite it that can be used during the holiday period.



Access is on foot along the beach from Borth y Gest or via the Wales Coastal Path and so it is not a beach for those less mobile or requiring the use of a pushchair or wheelchair.

Flaura and fauna
Weather & tide

However knowledge of the estuary is essential due to sandbanks.


The currents are strong and so swimming is not advised.


If you launch from the beach at Borth y Gest they are good bays to target.


Fishing is excellent along this stretch as it’s where the rivers Glaslyn and Dwyryd meet. The chances of catching a good size Bass are high, especially at dusk when the beaches are quieter. There is also an abundance of Flatfish in the estuary. Be careful not to hook a Weaver Fish, as they too are in abundance here and they’re poisonous.
