Anglesey in Autumn: Where Atlantic Storms, Grey Seals, and 12th-Century Stone Collide

The first time I stood on the cliffs at South Stack in late October, a gale was coming in from Ireland with enough force to make me reconsider every life choice that led me to this particular patch of rock. Rain stung my face horizontal. The lighthouse beam cut through grey murk. Below, waves smashed against cliffs that have been taking this punishment since before the Romans bothered to map the place.

Anglesey doesn't do gentle in autumn. It does dramatic.

This is when the island reveals itself. The summer caravans have retreated to storage. The ice cream shops board up their windows. What remains is a 276-square-mile chunk of Welsh granite thrust into the Irish Sea, populated by farmers who've been here for generations, seabirds that treat the place like a service station on their way to somewhere warmer, and grey seals that haul themselves onto beaches to give birth while Atlantic storms cheer them on.

If you're looking for a nice autumn break with pleasant walks and cozy evenings, try the Cotswolds. Anglesey is for people who want to feel something.

About the Author: Finn O'Sullivan

I'm the kind of traveller who reads local history before bed and asks pub landlords about their grandparents. I've spent twenty years exploring places where the past isn't preserved in museums—it's built into the walls, spoken in the pubs, and walked in the fields. I wrote my first book about the pubs of the Yorkshire Dales and have since covered the Hebrides, the west coast of Ireland, and the post-industrial landscapes of South Wales. Anglesey is different. It's older than the concept of Wales itself, yet it feels immediate, raw, and stubbornly alive. The island doesn't welcome you easily, but once it does, you don't forget it.

When to Come and What to Expect

Autumn arrives on Anglesey with little warning. September might fool you with mild days and golden afternoons, but by October the Atlantic has remembered it has unfinished business with this coastline.

September (12-17°C): The best weather window—settled, with golden light. The bracken turns rust-copper. The heather on Holyhead Mountain clings to purple.
October (9-14°C): Storm season. Low-pressure systems track across the ocean and unload on the western coast. The waves at South Stack throw spray 30 metres up the cliffs. Spectacular, terrifying, addictive.
November (6-11°C): Strips everything back. The days are short. The weather is wild. And the seals are pupping.

Grey seals—Halichoerus grypus—come to Anglesey's beaches in autumn to give birth. It's one of Britain's great wildlife spectacles. The mothers haul out onto secluded coves and give birth to pups covered in white fur. For three weeks, they don't feed themselves. They stay with the pups, nursing them with milk that's 60% fat. Then they leave. The pups, now weaned and alone, spend a few miserable days figuring out how to be seals before heading to sea. It's brutal. It's beautiful. It's autumn on Anglesey.

Getting There and Getting Around

Anglesey is connected to mainland Wales by two bridges across the Menai Strait. Thomas Telford's suspension bridge (1826) still carries the A5. The Britannia Bridge (1850, rebuilt 1980) carries the A55 expressway and the railway.

By Car: From London, four and a half hours via the M6, M56 and A55. From Manchester, ninety minutes. Once on the island, you'll need a car. Public transport exists, but many places are at the end of single-track roads with grass growing down the middle. Rent something sturdy. The roads have potholes that could swallow a bicycle. Parking at main attractions: £3–5.

By Train: Trains to Holyhead from London Euston take about three and a half hours with a change at Chester or Crewe. Holyhead is also a major ferry port for Ireland, which gives the town a particular character: part Welsh maritime history, part transit lounge.

By Bus: Buses run between main towns, but don't rely on them for coastal exploration. The DalesBus Explorer ticket is £12 for unlimited Sunday travel (Easter–October).

Where to Base Yourself

Holyhead is the biggest town, with the most accommodation, and puts you near the wild western coast. In reality, it's a working port with all the architectural charm that implies. Useful, but not charming.

The Harbour Hotel, Holyhead: Newry Beach, Holyhead LL65 1YD. 01407 762100. £85–110/night. Harbour views, basic but clean rooms, decent bar. Functional, not charming.

Beaumaris is where you stay if you want pretty. The town faces Snowdonia across the Menai Strait. It has a castle, a pier, and more craft shops than any town needs. It's also got some of the best places to eat on the island.

Ye Olde Bull's Head Inn, Beaumaris: Castle Street, Beaumaris LL58 8AP. 01248 810329. £120–160/night. A coaching inn from 1472. Beams, fireplaces, authentically creaking rooms. Excellent restaurant. Book well ahead for autumn weekends.

Menai Bridge is practical. Right on the strait, good restaurants, quick escape to the mainland if the weather turns biblical.

The Anglesey Arms, Menai Bridge: 29 Church Street, Menai Bridge LL59 5EF. 01248 712789. £90–120/night. Pub with rooms overlooking the Strait. The tide races below. Simple, comfortable, well-kept beer.

Rhosneigr on the west coast is for surfers and people who want to be close to the sea. The Oyster Catcher restaurant here is worth the trip regardless of where you're staying.

I usually stay near Cemaes Bay on the north coast. Small, a couple of decent pubs, and within striking distance of both the dramatic western cliffs and the more sheltered eastern side. The coastal path from here is spectacular.

The Harbour Hotel, Cemaes Bay: Church Road, Cemaes Bay LL67 0HH. 01407 710333. £80–110/night. Harbour-side pub with rooms. The fish and chips are decent. The landlord knows the local fishing forecast.

The Wild West: Cliffs, Lighthouses, and the Atlantic's Temper

South Stack and Holyhead Mountain (53.3065°N, 4.6839°W)

There's a reason every guide to Anglesey includes South Stack. The lighthouse sits on a small island separated from the main cliff by a 30-metre chasm. A suspension bridge—not for the vertiginous—connects them. Below, the sea churns. Above, choughs—those rare red-billed crows that have made Anglesey their stronghold—ride the updrafts with apparent indifference to physics.

But here's what the standard guides don't tell you: come at dawn in autumn, when a storm is clearing. The light is extraordinary. The clouds break in theatrical fashion. And if you're lucky, a peregrine will cut through your field of vision at eye level, hunting the rock doves that nest on the cliff.

Practical details:

RSPB car park: £5 (free for members). Get there early—storm watchers converge when the Met Office promises "significant wave action."
The café does a decent bacon roll and has windows that make storm watching comfortable. Open 10:00 am – 4:00 pm in autumn.
The suspension bridge to the lighthouse island: £5.50 adults. Open 10:00 am – 4:30 pm (last entry 4:00 pm). Not open in high winds.

The walk across Holyhead Mountain from here is non-negotiable if the weather permits. It's not a mountain by any real definition—220 metres—but the terrain is rough, the views are immense, and in autumn the bracken glows copper and gold. You'll pass hut circles from the Iron Age. You'll see North Stack, South Stack's smaller sibling, with its abandoned fog signal station. Allow three hours for the circular route. Wear proper boots—the path crosses boggy ground and rocky outcrops that will punish inadequate footwear.

The Church in the Sea: St Cwyfan's (53.1914°N, 4.4758°W)

St Cwyfan's Church sits on a small tidal island off the west coast. A causeway—sometimes submerged, sometimes not—connects it to the mainland. The building dates to the 12th century, though it's been rebuilt so many times that pinning down its age is an exercise in optimism.

In autumn, this place has a particular melancholy. The churchyard contains graves weathered smooth by salt and wind. The yew trees are ancient. When the tide is high and the causeway covered, the building becomes genuinely isolated—a stone prayer thrown into the Irish Sea.

The beach here is also where seals haul out in autumn. Check the tide tables before visiting—HW Holyhead +0130 is the rough calculation. If the tide is coming in, don't get caught on the island. The sea moves fast here.

To find it: Head for Aberffraw and follow signs for St Cwyfan's. The lane ends in a small parking area. Ten-minute walk to the beach. No entry fee. No opening hours. Just a church, a beach, and the Atlantic.

The East and South: Forests, Castles, and Sheltered Shores

Newborough Forest and Llanddwyn Island (53.1356°N, 4.4047°W)

Newborough is 2,000 acres of Corsican pine planted in the 1940s to stabilise the dunes. In autumn, the pines turn bronze, the bracken becomes a sea of gold, and the forest floor erupts with fungi. Fly agaric—the red-and-white toadstool of fairy tales—grows here in profusion.

The squirrels here are red. Not the invasive greys, but the native Sciurus vulgaris, russet-coated and tuft-eared. Autumn is when they're most active, gathering winter stores, chattering from the branches.

The forest gives way to beach—a vast expanse of sand facing southwest toward the Lleyn Peninsula. And at the far end, when the tide permits, is Llanddwyn Island.

Llanddwyn is named for St Dwynwen, the Welsh patron saint of lovers. Her church is in ruins, but the place retains a romantic charge—helped by two lighthouses, Celtic crosses, and the evening light hitting Snowdonia across the water.

In autumn, this is seal country. The beaches around Llanddwyn are pupping sites. Walk quietly, keep your distance (100 metres minimum), and keep dogs on leads.

Practical details:

Car park: £5 in summer, £3 in autumn. Cash or card.
Visitor centre: toilets, maps, small café. Open 10:00 am – 4:00 pm in autumn.
The café does surprisingly good cake. The coffee is adequate. The view is excellent.

Beaumaris Castle (53.2643°N, 4.0897°W)

Edward I built Beaumaris to be the perfect castle. It was never finished—money ran out, Wales was more or less conquered anyway—but what's there is still impressive. Concentric walls, a moat, towers, gatehouses. The whole medieval greatest hits album.

In autumn, with mist on the moat and the sun low enough to cast long shadows through the arrow slits, it feels properly ancient. The tourist numbers are down. You can stand in the courtyard and imagine what it must have been like to be stationed here, on the edge of the empire, looking out at Snowdonia and wondering if the Welsh were going to try again.

Practical details:

Entry: £9.50 adults, £6.00 children. Cadw property. Members free.
Open: 9:30 am – 5:00 pm (Apr–Oct), 10:00 am – 4:00 pm (Nov–Mar).
Allow 1.5–2 hours. The spiral stairs are steep and narrow.

Plas Newydd and the Menai Strait (53.1889°N, 4.2164°W)

After days of Atlantic wind, Plas Newydd feels almost Mediterranean. The house sits on the banks of the Menai Strait in a shelter belt of trees that the Marquess of Anglesey planted specifically for autumn colour. They turn the hillside into a bonfire of reds, oranges, and golds.

The house itself is a stately home with the expected features—the Rex Whistler mural that tricks the eye, the military museum, the furniture nobody has sat on for a hundred years. But the gardens are the reason to come in autumn. The camellias are blooming. The rhododendrons are showing their fall colours. And from the Italianate terrace, you look across the Strait to Snowdonia, where the first snows are beginning to whiten the tops.

Practical details:

Entry: £14.50 house and gardens, £9.50 gardens only. National Trust. Members free.
Open: 10:30 am – 4:30 pm (house), gardens 10:00 am – 5:00 pm.
The Courtyard Café does good soup and Welsh cakes. Open 10:00 am – 4:30 pm.

The North Coast: Quiet Intensity and Seal Pups

Cemlyn Bay and the North Coast (53.4117°N, 4.5167°W)

Cemlyn feels like the edge of something. A shingle ridge separates a brackish lagoon from the open sea. On the ridge, the wind is constant. In autumn storms, the spray flies over the top and drifts across the road like horizontal rain.

The lagoon is important for birds. In autumn, it fills with wildfowl—wigeon, teal, goldeneye. There's a bird hide where you can watch without disturbing them.

Walk east from here along the coastal path and you come to St Cwyfan's. Walk west and you reach Porthwen, a small cove with an abandoned brickworks that has a post-industrial beauty. The north coast is less visited than the west. The cliffs are lower, the drama more subtle. But on a wild autumn day, there's nowhere on the island I'd rather be.

What to Do: Storms, Seals, and the Coastal Path

Storm Watching

When the Met Office issues a yellow warning for wind, sensible people stay indoors. On Anglesey, they drive to the coast.

South Stack is the classic storm-watching location. The cliffs are high enough to be safe (don't go down to the bridge in high winds). The waves break with enough force to rattle your sternum. But there are other spots: Cemlyn Bay, where the shingle ridge takes the full force of the Atlantic; Porth Dafarch, where waves funnel into a small cove and explode upward; the Holyhead breakwater, all 2.4 kilometres of it, where you can walk out into the storm and feel properly small.

Bring waterproof everything. Not water-resistant. Waterproof. A change of clothes in the car is advisable. Hot drinks in a thermos are essential.

Seal Watching

Between September and November, grey seals give birth on Anglesey's beaches. This is not a zoo experience. There are no barriers, no guides, no guarantee. The rules are simple: stay 100 metres away minimum. Keep dogs on leads—a dog can cause a mother to abandon her pup. Never get between a seal and the water. If a seal is watching you, you're too close.

Good spots include the beaches around Llanddwyn Island, Porth Wen on the north coast, and various coves along the west coast best found by walking the coastal path. The Wildlife Trust of South and West Wales has volunteer seal guards at some locations. Early morning and late afternoon are best. Bring binoculars, patience, and respect.

Walking the Coastal Path

The Anglesey Coastal Path is 140 miles long. You don't need to walk all of it. What you should do is walk sections in autumn, when the summer vegetation has died back, the views are open, and you can have miles of coastline to yourself.

The section from Cemaes Bay to Cemlyn is dramatic and relatively easy. The section from Rhoscolyn to Trearddur Bay takes you past seal beaches. The stretch around Holyhead Mountain gives you South Stack and North Stack and the feeling you're at the edge of the known world.

OS Explorer maps 263 and 264 cover the island. The path is well-marked with acorn symbols, but autumn weather can make navigation challenging. Know where you are. Know your escape routes.

Pub Culture

Anglesey is Welsh-speaking. Not tourist Welsh—real Welsh, spoken in shops and pubs and kitchens. The island has a particular character: independent, slightly reserved, not interested in performing Welshness for visitors. But if you make an effort, if you show respect, you'll find a warmth that takes time to uncover.

The pubs are where this happens. The Adelphi Vaults in Amlwch, where the copper mining history hangs in the air like smoke. The Boston Arms in Holyhead, which has been serving sailors since before the Irish ferry was a thing. The Anglesey Arms in Menai Bridge, where you can watch the tide race through the Strait while working through a pint of local ale.

In autumn, these places become essential. You walk the coast in weather that tests your resolve. You get wet, cold, windswept. Then you find a pub with a fire and a pint of something dark, and the world returns to manageable proportions.

Try the cask ales. Purple Moose from Porthmadog is common. Welsh whiskey exists—Penderyn makes a decent dram—but cider is the traditional Anglesey drink, farmhouse stuff that will make you reconsider your relationship with sobriety.

Where to Eat and Drink

The Oyster Catcher, Rhosneigr

Beach Road, Rhosneigr LL64 5JG. 01407 810710.
£££ (mains £18–28, tasting menu £55). Open 12:00–2:30 pm, 6:00–9:00 pm (Wed–Sun), closed Mon–Tue in autumn.
Booking essential. The seafood is caught locally and cooked simply. I had the Anglesey sea bass with samphire and lemon butter (£24). Excellent.

The White Eagle, Rhoscolyn

Rhoscolyn, Holyhead LL65 2NJ. 01407 860330.
£££ (mains £16–26). Open 12:00–3:00 pm, 6:00–9:00 pm daily.
Booking recommended. Gastropub with proper ambition. The slow-cooked Anglesey lamb shoulder (£22) fell apart. The red wine jus was rich enough to require a nap.

The Bull, Beaumaris

Castle Street, Beaumaris LL58 8AP. 01248 810329.
££ (mains £12–18). Food served 12:00–9:00 pm daily.
A coaching inn from 1472. Beams, fireplaces, the faint smell of centuries of spilled beer. Welsh rarebit (£8.50), cawl (£13.95), beef and ale pie (£14.95). The pie had proper suet pastry and rich filling. This is what pub food should be.

The Harbourfront Bistro, Holyhead

Newry Beach, Holyhead LL65 1YD. 01407 762100.
£££ (mains £15–24). Open 12:00–2:30 pm, 6:00–9:00 pm (Tue–Sat).
Modern Welsh cooking in an unambitious town. The pan-seared scallops with black pudding and pea purée (£18) were plump and crisp. Ambitious cooking where you don't expect it.

Dylan's, Menai Bridge

St George's Pier, Menai Bridge LL59 5EE. 01248 716688.
££ (pizzas £12–16, mains £15–20). Open 12:00–9:00 pm daily.
Pizza and seafood in a converted lifeboat station. The wood-fired oven turns out excellent pizzas. The mussels come from the Menai Strait. The seafood pizza (£15.50) had a thin, charred base and generous seafood.

The Straits, Menai Bridge

20 Church Street, Menai Bridge LL59 5EE. 01248 712789.
£££ (mains £16–24). Open 12:00–2:30 pm, 6:00–9:00 pm (Wed–Sun).
Gastropub with local sourcing. The sirloin steak (£24) was hung properly, cooked to medium-rare. Triple-cooked chips, sharp béarnaise. The kind of meal that makes you want to move to Anglesey.

The Harbour Hotel, Cemaes Bay

Church Road, Cemaes Bay LL67 0HH. 01407 710333.
££ (mains £11–16). Food served 12:00–8:00 pm daily.
Harbour-side pub with decent fish and chips. The cod and chips (£12.95) had crisp batter and flaky fish. The view of the harbour made up for any culinary shortcomings.

What to Skip

Holyhead town centre: The ferry port is functional but charmless. Use it as a base if you must, but don't spend days exploring it. The breakwater is interesting. The town is not.
Beaumaris on a summer bank holiday: In autumn it's fine. In August it's a traffic jam of ice cream and gift shops. You came for the storms, not the crowds.
The "gift shop" at any National Trust property: Identical tat sold at inflated prices. The cafés are good. The shops are not.
Porth Dafarch in a storm unless you're experienced: The waves funnel into this small cove and explode upward. It's spectacular from the cliff top. It's dangerous at sea level. People have been swept off the rocks here.
Trying to visit everything in one day: Anglesey is bigger than it looks. Holyhead to Beaumaris is 40 minutes. South Stack to Llanddwyn is an hour. Pick two things per day, or you'll spend your trip in the car.
Any restaurant with a "seafood platter" on the menu: It's frozen, imported, and overpriced. Eat at The Oyster Catcher or The White Eagle, or stick to pub grub.
The Llanfairpwllgwyngyll train station gift shop: Yes, the name is long. No, the souvenirs are not worth it. Take a photo of the sign and leave.

What Not to Miss

South Stack at dawn, when the storm is clearing and the light turns the cliffs gold
The sound of choughs calling on Holyhead Mountain—they're rarer than golden eagles in Britain
A pint by the fire at the Anglesey Arms, watching the tide race through the Menai Strait
The moment you see your first grey seal pup on a beach—white, vulnerable, and utterly wild
St Cwyfan's Church when the tide is high and the causeway is covered, turning it into a true island church
The bracken on Holyhead Mountain in late October—copper, gold, and rust against the grey Atlantic
A conversation with a Welsh-speaking farmer in a pub—they know this island in ways no guidebook can capture
The Rex Whistler mural at Plas Newydd—it tricks the eye in ways that make you question what you're seeing
The drive along the west coast at sunset, with the Atlantic on your left and the last light turning the fields orange
The feeling of being properly small, standing on a cliff in a storm, while the Atlantic does what it's done for ten thousand years

The Honest Verdict

Anglesey in autumn is not for everyone. It demands something of you—proper clothing, physical effort, a willingness to be uncomfortable. The weather will test you. The wind will find every gap in your jacket. The rain will arrive horizontally. Your hair will never recover.

But it gives back more than it takes. The storms, the seals, the slant of light through clouds that have travelled across an ocean to get here. The sense of being at the edge of things, where Wales stops and the Atlantic begins. The pubs where the fire is real, the beer is local, and the conversation moves at the speed it should.

I spent five days here in late October. I watched a storm throw spray 30 metres up the cliffs at South Stack. I saw a seal pup take its first swim while its mother watched from the shallows. I ate a pie in a pub that's been serving travellers since 1472. I walked the coastal path in rain that found every seam in my jacket and didn't care.

Would I return? Yes, but in September for the golden light, or in November for the raw wildness. Late October was perfect storms but the days were short.

Who is this for? People who find beauty in wildness. Those who prefer cliffs to comfort. Walkers who don't mind mud. Anyone who's ever looked at a storm and thought, "I want to be in that."

Final advice: Pack waterproof everything. Check the tide tables. Learn three words of Welsh. And when the storm comes, go outside. The best moments happen when you're cold, wet, and exactly where you should be.
