Cemaes Bay & Traeth BachCemaes Bay, Anglesey

Cemaes Bay and Traeth Bach, Anglesey, North Wales

Cemaes Bay is actually made up of two beaches, Traeth Mawr (Big Beach) and Traeth Bach (Small Beach). Both offer safe swimming, sand, and plenty of rock pools for the kids. 
Traeth Mawr, the main beach, is east of the small harbour on the southern corner, backed by a seawall and sheltered by a small promenade, with the Afon Wygyr (River Wygyr) running into the sea to the west. To the west of the harbour is Traeth Bach and, as its name suggests, is the smaller of the two. It's made up of sand and rocks.


The harbour, with its small quay and marina, is a pretty sight, and both beaches are overlooked by the sweet little seaside village of Cemaes. The village has all the facilities you possibly need for a lovely day out. Once a flourishing fishing harbour and port, today Cemaes is primarily known as a popular holiday spot.

With its stacks of lobster pots and other fishing paraphernalia on the harbour wall, this picturesque bay has something for everyone There's plenty of sand for castles, crabbing and jumping to be had off the promenade, walks with breathtaking scenery in every direction -  plus watersports and boating activities galore!

On the whole sheltered and safe.


Yes. Cemaes Bay is popular with anglers, both from boats and the shore. The surrounding cliffs and ledges offer lots of choices. Head to the Llanbadrig Ledges/Llanbadrig Point, just around the headland to the east. You’ll need to pass through the cemetery at St Patrick's/Padrig's Church, with the ledges you’re after just below you, slightly to your right. The headlands of Trwyn y Penrhyn, Trwyn y Parc are great too. The water off the cliffs is relatively deep, but can be a bit snaggy.

The area is known for Pollack, Bass, Tope, Whiting, Mackerel, Bull Huss, Coal Fish, Cod, Conger Eels, Dogfish, Flounder, Coalie and Ling - to name but a few!
