Trefor Beach - Gwynedd

Trefor Beach is situated on the north coast of the picturesque Llyn Peninsula. Set in front of the little fishing village of Trefor the beach here has a spectacular backdrop of the mountains of Snowdonia.
The beach and harbour here are an extremely important part of the history of the area as this was one of the major granite producing regions of Wales with a large local quarry. In days gone by this would have been transported to Europe from Trefor which is how the harbour developed.

The beach here is a mixture of small pebbles and sand and is well protected by the encircling headlands, although strong winds still blow from the North West side. Trefor Beach backs onto land that dates from the last glaciations and is made up of boulder clay which periodically crumbles into the sea. There is also a pier here which stretches for nearly 200 meters into the sea and is often used by local fisherman. At times however the pier is closed for renovations so note that it may be inaccessible during a visit.

Offshore from Trefor Beach on the outside of the harbour wall sits a sharp reef which means that the surfing conditions here can be excellent when there is a swell running. If you want to walk down to the beach then there is a rambling trail that goes from the village to Trefor Beach and skirts past the local playground.

In the local area you will also find other points of interest such as the Church of St Beuno, which is part of the Pilgrims' Route that winds all the way to Bardsey Island just off the western tip of the Peninsula.
