A long sand and shingle bay in Caernarfon Bay with mountains as a backdrop. Backed by the small village of Pontllyfni, this is a remote and peaceful beach location. There is a beach resort here which has its own private access to the beach.


A fantastic spot for coastal walking and fishing. Caernarfon town with fortress, castle and shops is not far away.

Wildlife and Walks

Paths run along the coast and river bank with a pleasant picnic site a few miles to the south. Snowdonia National Park and the Isle of Anglesey are just a stones throw away.

What's tested here?

Water samples are not taken at this beach because it has not been designated as a bathing water and there is no voluntary sampling.
Why isn't this a designated bathing water?

High levels of bacteria in the water can indicate pollution from sewage treatment works or polluted rain water draining from the land.
Where does pollution comes from and how can you help?

Water quality can be reduced for up to 72 hours after heavy rain. Look out for temporary signs at the beach and on our website.
