Cemaes Bay, Anglesey: the beach and the harbour breakwater with the village terraces rising behind

Isle of Anglesey · North coast

01The village

A harbour with a beach on either side of it


Cemaes is arranged around one sheltered inlet. The stone breakwater and the boats sit in the middle; Traeth Mawr, wide and sandy, opens north-east of it, and Traeth Bach, small and rocky, is a few hundred metres the other way. The village itself (High Street, the chapels, the shops and the Heritage Centre) sits a couple of minutes inland, across the bridge over the Afon Wygyr. All of it is flat.

Why it matters

Two completely different shorelines, a working harbour and a village you can walk end to end, and then a cliff path that turns the stop into a proper half day. Few places on Anglesey give you that much variety inside one short walk.

Character

A working village, not a resort

Boats still use the harbour; the shops and chapels behind it serve the people who live here.

Pace

Flat, and small enough to walk

Beach, harbour and High Street are minutes apart; only the cliff path asks anything of you.

Landscape

North-facing, between two headlands

An inlet open to the Irish Sea, with cliffs east towards Llanbadrig and the Wylfa headland west.

Best for

A beach day that turns into a walk

Best for families on the sand, and for anyone willing to keep going east along the cliff.

The moments that define a visit

The harbour that made the village

Small boats still lie inside the same stone arm that sheltered the ships once built here.

A bronze bell stands out on the sand that nobody plays; the rising tide moves the clapper.

The other beach, minutes away

Cross the harbour and the shoreline changes entirely: pebbles, weeded rock and pools instead of sand.

Beyond the first defining moments, the fuller Cemaes catalogue continues below.

Find your bearings

The harbour is the middle of everything. Traeth Mawr opens to its north-east, Traeth Bach to its south-west, the village sits inland behind the bridge, and the cliff path runs a mile north-east to Llanbadrig.

What to see and do

Six stops, from the harbour in the middle of the bay to the church on the cliff a mile north-east. No cafés, pubs or shops are named here; see Local life for the village's everyday character.

Walk the breakwater arm and you see how the whole village is arranged around one sheltered inlet. This harbour is why Cemaes is shaped as it is.

03Story

A port at the top of Wales

The name means a bend or an inlet, the shape of the bay itself. For most of its recorded life this was not a place people came to look at. It was a place things left from.

  1. Porth Wygyr, and a seat of the commote

    Before the conquest of 1282–83 this was a commotal seat under the Prince of Wales. Its older name, Porth Wygyr, belongs to the river that still runs out through the village to the sand.

  2. Herring first, then a working port

    Cemaes fished for herring before it traded. Through the 18th and 19th centuries it shipped out limestone, marble, bricks, corn and ochre and took in coal and flour, and ships were built in the shelter of the harbour itself.

  3. A breakwater rebuilt against the same sea

    The first breakwater went up in the 1830s. Storm damage in 1889 forced a replacement, and further improvements followed in 1900. The arm you walk today is the third answer to the same problem.

  4. Bricks, a tramway, and fourteen years

    A brickworks opened in the valley in 1907 with a Hoffman kiln and a tramway running down to the pier. It closed in 1914. The tramway's line is still there under the path through the trees.

  5. A lifeboat, and then a power station

    An RNLI station stood on the western headland from 1872 to 1932: sixty launches, forty-two lives. Wylfa began generating on the same headland in 1971, stopped on 30 December 2015, and in November 2025 was chosen for the UK's first small modular reactors.

The old tramway route from Cemaes harbour to the brickworks, now a woodland path with the rails still visible

The rails to the brickworks are still in the path. Nothing has run on them since 1914.

Atlas of Wales

Local life & everyday character

A village of 1,357, with a beach attached


The Llanbadrig community counted 1,357 people at the 2011 census, and most of them live behind the harbour rather than on it. High Street carries the cafés, pubs and shops, none of them named here as a recommendation, along with two 19th-century chapels, a clock-towered village hall and the war memorial.

Because the A5025 bypasses the village, nobody arrives by accident. The people you pass are either living here or have chosen to come, and a good number of them are walking the Anglesey Coastal Path straight through.

Local tip

The two beaches sit either side of the harbour and are nothing alike. Traeth Mawr is wide sand; Traeth Bach, five minutes round the inlet, is shingle, rock and pools.

Where the village lives

The working harbour

Boats and pots

Pot buoys, small boats and the harbour wall, and the trade is smaller than it was, but it never stopped.

The street behind it

Shops and houses

Painted fronts, a handful of shops and services, and the everyday business of a village that isn't only for visitors.

The sand and the path

Where everyone ends up

The beach is the village's shared ground, and the coast path leaves from the end of it in both directions.

Village rhythm

Morning
The beach car park fills first on a fine day; walkers on the coast path come through early.
Through the day
The promenade and the sand hold most people; High Street stays a working street.
Evening & off-season
The bay faces open water to the north, so the light and the wind both come off the sea; out of season the beach facilities thin out.

The village in one visit

Cemaes keeps its civic buildings where you can see them.

A clock tower on the village hall, two chapels within a few hundred metres of each other, a war memorial with its own inscription, and terraces looking straight down at the boats: the ordinary architecture of a village that has always had to pay for itself.

Plan your time

The village church was built without a graveyard, so its dead still go the mile to Llanbadrig.

The beach car park puts you between the two shorelines, so which one you start on is the only decision to make before you set off.
