Coastal Path

The 125 mile Anglesey Coastal Path provides an excellent vantage point to explore the rugged coastline and see a rich diversity of wildlife and geology.

Cemaes & Llanbadrig have TWO paths (maps available below):

More information is available on Visit Anglesey’s website, including informative path descriptions.


Cemaes has a range of wildlife – foxes, peregrine falcons. Usually, on Wylfa Head, you can see porpoises coming up for air. The currents around there are perfect feeding spots for them. Cemaes harbour is a perfect spot for fishing, as you can catch Atlantic mackerel, flatfish, red crabs and other fish and crustaceans. Near Cemaes is Cemlyn, which hosts the only breeding Sandwich terns in Wales.


The rocks exposed by coastal erosion in North Anglesey belong mainly to what geologists call the Mona Complex, which is among the oldest rock units seen in Wales. It underlies, and is therefore older than, the slates of the North Wales quarrying industry, but is probably not very much older in geological terms. Since the remains of fossilized remains have been found in the rocks, it does not pre-date the origins of life and is therefore probably about 600 million years old.

Area of Outstanding Natural Beauty

The Isle of Anglesey’s Area of Outstanding Natural Beauty (AONB) covers most of the island’s 201km coastline offering majestic land and seascapes to captivate and inspire you.  

Cemlyn Nature Reserve

Cemaes is a close neighbour to s coastal lagoon and shingle ridge at Cemlyn Nature Reserve  which is owned by the National Trust and managed by the North Wales Wildlife Trust.  During the summer months Cemlyn is home to one of the largest breeding colonies of sandwich terns but be prepared for a real  treat as Cemlyn attracts many rare birds. All North Wales Wildlife Trust events are advertised on their website (click here)


Many seabirds can be seen in the harbour and along the headlands at Cemaes.  Watch out for gulls swooping for your lunch! Gannets, Gulls, Guillemots, Fulmar and Kittiwake are in abundance and if you are lucky sitings of chough or raven. Curlew and Whimbrel can be seen on the surrounding fields when the tide is high, whilst heron, redshank and oyster catchers can be seen at low tide on the beach.


Once the stalwart of village industry, fishing is still popular.  Whether sea or shore fishing is your bag there is much bounty to be reeled in including bass, bull huss, coalie, coal fish, cod, conger eel, dab, dog fish, flounder, ling, mackerel, pollack, and whiting.
