Trefor beach, Llŷn Peninsula, North Wales

The beach at Trefor, on the northern coast of the Llŷn Peninsula, forms part of a quaint little harbour. It is a haven for boating, swimming, surfing and fishing.

The charming sand and pebble beach is protected from the Irish Sea by its harbour wall and tucked beneath the Llŷn’s highest hills. The village of Trefor sits above the sand, and the sheltered harbour was once a bustling port for the exportation of granite.


Trefor's pretty little harbour was once a key spot on the northern coast for the exportation of granite. The granite was quarried from the Y Eifl mountains and taken by horse and cart down to the harbour. The harbour and the wall provide shelter for a sandy beach of about 100 metres long. There are breath-taking views down the Llŷn Peninsula from the village itself that sit above the harbour.

The beach is a nice mix of sand and pebbles and the harbour area is great for swimming and for anchoring up due to its sheltered nature. When the wind is from the southerly quarter and there is a big swell running, there is a great wave to surf on the west side of the pier that breaks down the point. When the swell is running the car parks become busy with surfers checking the wave. The 200m long pier itself helps to shelter the harbour and there is a slipway in the harbour for launching.

At a Glance
  • The harbour is great for bathing.

  • The village serves the beach well with a few handy shops for stocking up.

  • The wave that breaks the other side of the pier is a well-known spot for the local surfers.

  • There is great fishing off the base of the pier. Please note that access to the main part of the pier is not possible.

Sandy and pebbly. The beach at Trefor is part of the village itself as it virtually sits on the sand. Trefor is signposted off the A499 between the villages of Gyrn Goch and Llanaelhaearn.

There is a slipway for launching and there is parking adjacent to the beach that is free. There are public toilets and an emergency phone. The proximity to the centre of the village means that it is easy to reach using public transport. The village is also home to a small village Post Office and a shop along with a cafe.

The beach is suitable for prams and wheelchairs as there is a slipway down onto the sand when the tide is on its way out.

When the swell is from the right direction, there is a popular break off the pier. For some local advice on surfing, consult who have a wealth of local knowledge of when the breaks are at their best.


Yes - there is a slipway for launching.


The water beneath the pier is a popular dive site as the pier itself has become a man-made reef, full of fish. The ban on anglers on the pier also means that there is little chance of getting snagged!


Fishing off the main pier has been stopped due to it being unsafe, however, anglers still fish off the concrete end of the pier and the spot is known for throwing up some large bull huss and the odd tope, along with your usual shore fishing for pollack, mackerel and more.
