Trefor Beach

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.

On the outside of the harbour wall the surfing conditions can be good when there is a big swell running, but it isn’t a spot for beginners. 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.

Scruffy dirty dump

Apr 13th 2022

Went to Trefor for a long weekend and it has to be the worst village and beach on the Llyn Peninsula. Locals unfriendly , a few loud scousers ruining the peace , litter,  dog poo. The village itself is very drab bleak and looks poor . Definitely not a tourist or holiday destination.  Don’t waste your time or money visiting , there are nicer places to go with nicer locals !

many yrs fishing since 1960s

fished the pier many times…mostly dogfish.  awkward place to get to ..    locals not really friendly   bit of a dump really   could be done up nicely to promote a nice little business area and upkeep of launching area….but no !!!

Slipway has been closed for some time and to be honest I’m trying to find out if this is legal . Been told locals didn’t like the idea of so many people launching there but I’ve been going there for 40 years fishing and to be told can no longer launch there is not right . If there is any 1 who can give me advise on this I would appreciate it . Thank you

Interesting views, seemingly good place to surf. Shame the locals took a dislike to my car and smashed their car door into it. Bitters.

What did we get wrong?
