Morfa Bychan Beach

Morfa Bychan Beach - Gwynedd
© STEVE POVEY and licensed for reuse under this Licence

Morfa Bychan, known locally as Black Rock Sands, is a sandy beach, with rocky areas- although the rocks aren’t actually black.  The beach stretches for about 2 miles and is backed by a dune system which has been designated a Site of Special Scientific Interest.  There are plenty of rockpools to explore here as well as some interesting caverns.

A river mouth lies at the south-eastern end of the beach, and the village of Morfa Bychan is a few hundred meters away. The beach has lovely views of the mountains and countryside of Snowdonia National Park.

A slipway provides vehicular access to the sands and most visitors park on the beach, making it a popular picnic destination and providing easy access for those with mobility problems. There are designated bathing and boat launching areas. Dogs are banned from the central section of the beach, but are allowed on the eastern and western sections.

There are a number of holiday parks in the area surrounding the beach. In the village of Morfa Bychan there are shops, places to eat and a golf club. There are more facilities in the town of Porthmadog, about 2 miles from the beach.

Morfa Bychan Beach Reviews

Good large Sandy beach

Aug 24th 2021

Able to drive onto beach but pricey at £5. Good gently shelving sands and bathing.
Beach entrance now from far (black rock) end only . Previous entrance from ‘Beach Road’ now closed. Some beach vendors. - -Squalid W.C’s.
Zoned water sports area in centre.
Dog free zone at Black Rock end but sadly not enforced or policed.
