The coast that keeps falling in

In the eleventh century, Dunwich was one of the largest ports in England, a city with a harbour, a mint, shipyards, and somewhere between eight and eighteen churches, depending on which account you believe. Today it’s a hamlet with a pub, a car park and a beach. The rest of it is under the sea, a mile or so offshore, and it went in storm by storm over about four hundred years while people watched.

That is the East Anglian story, and it isn’t history. This is the fastest-eroding coastline in Britain, and it is still going. Soft cliffs of clay, sand and crag give way constantly; the sea takes metres a year in places. Villages have been abandoned within living memory.

For a hunter, that erosion is the whole point, because it keeps handing things back. At West Runton in 1990, a storm exposed the most complete mammoth skeleton ever found in Britain: a steppe mammoth around 600,000 years old, twice the weight of an African elephant. At Pakefield, flint tools were pulled from the cliff base that pushed the date of the earliest humans in northern Europe back to roughly 700,000 years ago. At Walton-on-the-Naze, the red crag cliffs shed sharks’ teeth and shells by the bucketload.

None of that is sea glass. But it tells you what kind of coast this is: one where the ground is permanently being turned over and delivered to the beach, and where what you find today wasn’t there last winter.

The glass itself comes from what East Anglia has always been: fishing towns, small ports and Victorian resorts. Adnams has brewed in Southwold since 1872 and bottled there ever since. Aldeburgh built ships, including one of Drake’s. Cromer has landed crabs for centuries. Lowestoft was the busiest fishing port on the east coast. It’s domestic and maritime rather than industrial, so this isn’t County Durham. But it’s mostly shingle, which holds glass far better than sand, and shingle plus constant erosion is a decent combination.

One practical thing to know before you plan anything. The tide nearly stops in the middle of this coast. Around Lowestoft the spring range drops to roughly two metres, one of the smallest in Britain, and it grows again as you go north to Cromer and south to Essex. Same beach conditions, wildly different amounts of foreshore.

East Anglia sea glass at a glance

Best overall: Walton-on-the-Naze
The Naze cliffs erode faster than almost anywhere in Britain and hand material back constantly. Red crag full of fossils, a 1720 navigation tower on the headland, and a long shingle and sand beach below. The most productive hunt in the region.

Best for beginners: Southwold
Beach huts, a pier, a lighthouse in the middle of the town and Adnams brewing round the corner. Easy access, plenty of shingle, and everything you need within a few minutes. Note the dog ban starts in April here, a month earlier than most.

Best for colour variety: Aldeburgh
A shipbuilding and fishing town since the medieval period, one of Drake’s ships was built here, with the fishermen’s huts still selling off the boats. A mile of wide shingle running north towards Thorpeness, and the best spread of finds in Suffolk.

Best for sea pottery: Cromer
Crab boats have worked off this beach for centuries and the Victorian resort trade layered on top of it. The pier, the church tower, and material going into the same water since long before either. Dogs banned from the sand entirely in summer.

Best without a car: West Runton
Its own station on the Bittern Line from Norwich, a few minutes’ walk from the beach. Chalk reef offshore, rock pools at low water, and the mammoth. Nowhere in the region is easier to reach by train.

Best dog-friendly: Walberswick
Dogs all year, no restrictions, on a wide shingle beach across the river from Southwold. Famous for crabbing, an artists’ colony for a century, and quiet in a way its neighbour isn’t. Trigger’s pick.

Best right now
With ranges varying from two metres to nearly five along one coastline, conditions differ sharply between these beaches. The Sea Glass Score updates daily.

How the coast divides

North Norfolk: Cromer, West Runton – has the biggest tidal range in the region at around four and a half metres on springs, a chalk reef offshore, and soft cliffs behind. The most exposed and most dramatic end.

The Suffolk coast: Pakefield, Southwold, Walberswick, Aldeburgh- is shingle almost throughout, which is the best terrain for glass anywhere. It’s also where the tidal range collapses to around two metres, so there’s very little drop and the productive band is narrow. Storm-driven hunting.

Essex and the Naze: Walton-on-the-Naze sits where the range picks up again towards the Thames estuary, around four metres. Crag cliffs, saltmarsh behind, and the fastest erosion of the lot.

Every East Anglia beach we’ve rated

Norfolk

Cromer: Fair
Pier, lighthouse, crab boats and a Victorian seafront. Soft cliffs behind that keep delivering. Dogs banned from the beach entirely 1 May to 30 September; promenade only.

West Runton: Fair
Where the mammoth came out in 1990. Chalk reef, rock pools and a good stretch of shingle, with a railway station a few minutes away. Seasonal dog restriction on the marked section.

Suffolk

Pakefield: Good Beach
Just south of Lowestoft, with a clifftop church and some of the fastest erosion on the coast. Flint tools found here in 2005 rewrote the date of the first humans in northern Europe. Quiet, and largely unrestricted for dogs.

Southwold: Good
The most complete seaside town on this coast: pier, lighthouse, beach huts, Adnams. Main beach closes to dogs 1 April to 30 September, but Denes Beach off Ferry Road is open all year.

Walberswick: Good
Across the Blyth from Southwold, reached by the rowing-boat ferry or the footbridge. Wide shingle, no dog restrictions, and far fewer people.

Aldeburgh: Good
Fishing huts on the shingle, Maggi Hambling’s Scallop up the beach, and Snape Maltings inland. The main beach restricts dogs in summer; the mile north from the Wentworth Hotel towards Thorpeness doesn’t.

Essex

Walton-on-the-Naze: Good
The Naze tower, the crag cliffs, sharks’ teeth in the fossil beds and constant erosion feeding the beach. The strongest hunt in the region.

What East Anglia sea glass actually looks like

Common: Green, brown and white. Brewery and bottling stock, fishing town waste, and a century of resort trade.

Occasional: Aqua and pale blue around the older ports Aldeburgh and Cromer in particular.

Rare: Cobalt and purple. Uncommon, as everywhere outside the industrial coasts.

Amber is worth a mention. Adnams has bottled at Southwold since 1872, and there were breweries at Lowestoft and along the coast too. The brown and amber proportion here is higher than you’d expect from resort towns alone.

And genuine amber, which is a different thing entirely. The East Anglian coast is one of the few places in Britain where Baltic amber washes up, fossilised resin carried across the North Sea, most often after north-easterly storms. At a glance, it looks a little like orange sea glass, but it’s much lighter in the hand, warm rather than cold, and it floats in salt water. Norfolk beaches are the best odds. If you find something orange here, weigh it in your palm before you assume.

Fossils on the same tideline. Sharks’ teeth and shells at Walton-on-the-Naze, and the Cromer Forest-bed material at West Runton and Pakefield. Collect from the beach, not the cliff.

When to go

Winter, after a north-easterly. This coast faces east and north-east into the North Sea, and that’s the wind that both moves material and brings amber in. A hard blow followed by a calm morning is the combination.

Storms matter more here than anywhere except the North East, because storms are what take the cliffs down. Every significant surge event completely reworks these beaches.

But don’t hunt during or immediately after one. These cliffs are unstable; they fall without warning, and East Anglia gets tidal surges that overtop defences. Stay off the cliff bases entirely.

In Suffolk, forget the moon. With a two-metre range around Lowestoft and Southwold, spring tides barely help. Go on weather.

In north Norfolk and Essex, springs are worth timing. Four to four and a half metres genuinely opens ground up at Cromer and the Naze.

Dogs across East Anglia

Three counties, several district councils, and no single pattern, but the region has more genuinely open beaches than most.

North Norfolk District Council restricts sections of Cromer, Sheringham, Mundesley, Bacton, Overstrand, Sea Palling, Walcott and West Runton from 1 May to 30 September. At Cromer and Sheringham, dogs are banned from the sand entirely during those months. The promenade only. West Runton’s restriction covers a marked zone rather than the whole beach, and the council is clear that responsible dog walkers are welcome on almost all its beaches outside those areas.

East Suffolk Council has the one date to watch on this coast. Southwold’s main beach excludes dogs from 1 April to 30 September, a month earlier than the standard pattern, and it catches people out every spring. Denes Beach off Ferry Road stays open all year.

Aldeburgh’s main beach from the southern end of Brudenell Street to Market Cross Place restricts dogs from 1 May to 30 September, but the mile of shingle north from the Wentworth Hotel to Thorpeness is open. Lowestoft and Felixstowe beaches have summer exclusions.

Walberswick has no restrictions at all, and neither do Dunwich, Shingle Street or Kessingland. Pakefield doesn’t appear on East Suffolk’s exclusion list either, though it’s worth checking signage.

Essex -Walton-on-the-Naze sits under Tendring District Council rather than Southend’s much stricter regime. The regional pattern is a 1 May to 30 September restriction on main bathing sections with dog-friendly stretches either side, so check on arrival and head away from the central beach.

Fixed penalties across all three counties are £100, rising to £1,000 at court.

For dog-friendly cafés and pubs, Yappy Places covers Southwold, Walberswick, Aldeburgh and the north Norfolk coast. This is good territory for it, and the Suffolk pubs in particular expect dogs.

Worth the stop, but not for the glass

Dunwich – the drowned city. There’s a museum in the village with a model of what was lost, and the beach itself is worth walking for the story alone. Dogs all year.

Blakeney Point – seal colony on the shingle spit, reached by boat from Morston.

Snape Maltings – Britten’s concert hall in a Victorian malt house on the Alde, ten minutes from Aldeburgh.

Orford Ness -the National Trust’s shingle spit, used for secret weapons testing including early radar and atomic trigger research. Unsettling and extraordinary.

Southwold Pier – for the Under the Pier Show, a collection of homemade satirical arcade machines that is genuinely unlike anything else in Britain.

Planning a trip

A day: Southwold and Walberswick. Twenty minutes apart via the ferry or the footbridge, two very different beaches, lunch in between.

A weekend, Suffolk: Base in Southwold or Aldeburgh. Southwold and Walberswick on day one, Aldeburgh and Thorpeness on day two.

A weekend, Norfolk: Base in Cromer. Cromer and West Runton on day one, then the wider north Norfolk coast on day two.

Essex works as its own day — Walton-on-the-Naze is over two hours from Cromer and closer to London than to the rest of the region.

Getting here without a car: the Bittern Line from Norwich serves Cromer, West Runton and Sheringham with stations right by the beaches. The best rail access in the region. Lowestoft is the railhead for Pakefield and Darsham for Southwold, both needing a bus or taxi. Walton-on-the-Naze has its own station on the branch from Colchester.

From beach to jewellery

East Anglian glass comes up well-rounded from the shingle, with more amber and brown than most coasts thanks to a century and a half of brewing. At Mermaid Tears, every piece of jewellery starts on a UK beach exactly like these, hand-hunted and handmade into something you’ll keep. Browse the collection

Disclaimer: Tide times, dog restrictions, parking charges and beach conditions change regularly. This region spans several district councils with separate orders on separate cycles; note in particular that Southwold’s dog exclusion begins on 1 April rather than 1 May. Always check current signage. The East Anglian coast is the fastest-eroding in Britain, with soft cliffs that collapse without warning and a history of tidal surge flooding. Never hunt beneath a cliff, take fossils from the beach rather than the cliff face, and check surge warnings in winter.

Frequently asked questions

Where is the best place to find sea glass in East Anglia?
Walton-on-the-Naze in Essex. The crag cliffs erode faster than almost anywhere in Britain and constantly deliver material to the beach below, and there’s a good spread of shingle to trap it. Aldeburgh is the strongest Suffolk alternative, with a mile of wide shingle running north towards Thorpeness.

Is East Anglia good for sea glass hunting?
Decent rather than exceptional. There was never heavy industry here the way there was in County Durham, so the glass is domestic and maritime in origin. What works in its favour is terrain and erosion: much of the Suffolk coast is shingle, which holds glass far better than sand, and the whole coastline is being reworked continuously.

Can you find amber on the Norfolk coast?
Yes. Baltic amber washes across the North Sea and comes ashore on East Anglian beaches, most often after north-easterly storms. It can look like orange sea glass at first glance, but it’s much lighter in the hand, feels warm rather than cold, and floats in salt water.

Are East Anglian beaches dog friendly?
Many are completely unrestricted. Walberswick, Dunwich, Shingle Street and Kessingland allow dogs all year. The exceptions are the resort beaches. Cromer and Sheringham ban dogs from the sand entirely from 1 May to 30 September, and Southwold’s main beach closes from 1 April, a month earlier than most of Britain.

When is the best time to hunt sea glass in East Anglia?
Winter, the morning after a north-easterly blow. This coast is storm-driven rather than tide-driven; the tidal range around Lowestoft drops to roughly two metres, among the smallest in Britain, so spring tides make far less difference here than they do elsewhere.

What happened to Dunwich?
It was one of England’s largest ports in the eleventh century and the sea took it, storm by storm, over roughly four hundred years. What’s left is a hamlet, a museum and a beach. It’s the clearest illustration anywhere of what the East Anglian coast does.
