Cemlyn Bay, Cemaes Bay, Anglesey, North Wales

Cemlyn Bay, including the Nature Reserve, is a fantastically interesting place to visit. There is so much to see - from a myriad of birds on the lagoon, coastal plants on the shingle beach, to the wonderful rock pools along the way! Valued for both its scenic qualities, as well as its unique range of beautiful wildlife, Cemlyn is just as popular with general visitors as it is with birdwatchers and naturalists.

The wonder of Cemlyn is that you can get extremely close to the birds without disturbing them. From the wonderful vantage point of the ridge, visitors can experience rare and enchanting birds flying overhead (often with fresh catches of sand eels and fish) - as well as chasing, diving, courting, incubating, tending to their chicks, preening and bathing. It is also possible to witness the stunning spectacle of the tern breeding period over the summer months!


The meaning of the name Cemlyn roughly translates as ‘bent’ or ‘crooked’ lake - and it’s not hard to see why it was named as such!  The bay is defined by the headlands of Cemlyn Point and Cerig Brith, and its fabulous curved beach has a unique feature - its naturally-created shingle ridge (known as Esgair Cemlyn) which divides the open sea from its coastal lagoon, considered to be the best example of its type in Wales!

It’s this feature that has given rise to the area’s international fame as it has attracted a huge tern colony, and is also home to the ONLY breeding colony of sandwich terns in Wales. A super place to take the kids for some natural history, or for some private wanderings. Cemlyn is truly special!

Beach info

Beach type



Other than an interpretation board, close to the car park, there’s not a lot else - so bring your own refreshments. However, for basic bits and bobs, you could pop into the Tregele Garage. Also, Cemaes Bay is less than 10 minutes away - where you’ll find a variety of shops, pubs and eateries etc.


Parking is at the pay and display car park, from which there runs a tarmac path for about 400m to the beach. There are disabled bays available in the car park itself.


There is easy access from both car parks but, be aware, they can become flooded (for up to an hour) either side of high tide.

Dog restrictions

Yes, dogs are allowed - but must be kept away from nesting birds!

Flora & Fauna
Weather & tide

Cemlyn is an excellent location for catching: Pollack, wrasse, dab, whiting, small codling, mackerel and dogfish. Like the rest of the coastline here, reaching all the way to Church Bay, it’s also known as a great place for sea bass! If you’re fishing from your kayak or a boat, you could make your way to Wylfa Power station’s ‘outfall’; apparently this is a sea bass hot spot!

There are lots of ledges and little coves which, although a distance away from the beach, are great fishing spots -  and worth the treck! You can also fish off the beach, especially at low tide.

During mackerel season you’ll see lots of people out and about trying their luck! One of the best fishing marks is said to be the headland, to the left of the main beach. From the carpark by Bryn Aber, turn left when you reach the beach, and from here it’s only a few minutes walk away.
