Why Seaham is in a league of its own
There are good sea glass beaches in the UK. And then there’s Seaham.
Seaham is internationally recognised as one of the finest sea glass beaches on Earth. Unlike most beaches where sea glass is an occasional lucky find, at Seaham it carpets the shoreline, a living legacy of Victorian industry that has been returning its treasures on every tide for over a hundred years. Collectors come from across the UK and beyond specifically for this beach, and it still delivers. That’s not hype. That’s just Seaham.
In the late 19th and early 20th century, the Londonderry Bottleworks, once one of the largest glass factories in Britain, operated along this stretch of coast, discarding waste glass directly into the sea, including beautiful end-of-day glass: multicoloured offcuts and overflows from artisan batches. The result is a beach unlike anywhere else in the world. Over 150 years of North Sea tides have tumbled those millions of fragments into the frosted jewels collectors come here to find.
This guide covers two beaches: Seaham Hall Beach to the north of the harbour, the main glass beach, easy to access, reliably productive, and Blast Beach to the south at Nose’s Point, a wilder, more rugged stretch for those willing to earn their finds. They’re two very different experiences, and both are worth knowing about.
What you’ll find here
Colours commonly found: Green, brown, white, blue, aqua
Occasional finds: Blue, Aqua, Amber, Turquoise
Rare finds: Cobalt Blue, Black, Lavender, Red, Yellow, Orange, Grey, pink Seaham specials: Multi-coloured end-of-day pieces- swirling, layered glass formed when workers swept the last remnants of coloured glass together at the end of each production shift.
These are unique to Seaham and a small number of similar industrial sites worldwide. Sea glass marbles also turn up occasionally.
When to go
Timing is everything at Seaham.
Arrive as the tide is ebbing- going out. Heavy swells churn up glass from the seabed that hasn’t seen the surface in years, and the day after a North Sea storm is as good as it gets anywhere in the UK. Winter is the prime season: the beach is quieter, storms are more frequent, and glass accumulates over the summer months before the winter tides begin returning it.
Around new and full moon, the tidal range is at its greatest, exposing more of the beach and bringing in material from further offshore. Spring tides at Seaham run to around 4.5 metres on a good day. These are your best days. Arrive early, Seaham attracts serious enthusiasts from across the country, and the strandline gets worked quickly once word spreads about post-storm conditions.
Overcast days are better than bright sunshine for spotting glass. When the sun is high, everything glitters, and the frosted texture of sea glass becomes harder to distinguish from wet pebbles. A grey day with good light and a low tide is the ideal combination.
Today’s Tide Times & Weather
Seaham sits on the Durham Heritage Coast facing east into the North Sea, with a tidal range of around 4–4.5 metres on a spring tide, generous exposure that reveals a substantial strip of new foreshore at low water. The tidal pattern is semi-diurnal, with the range varying considerably through the spring-neap cycle.
The widget below uses Seaham tide data, the nearest UKHO standard port, a few miles north, to show today’s Sea Glass Score, tide curve and best hunting window. Aim to arrive as the tide begins to ebb and work towards low water; the two hours either side of low tide at Seaham are the most productive window, when freshly uncovered pebbles are at their most rewarding, and the strandline is fully accessible.
Stop 1 — Seaham Hall Beach (North Beach)
Best For:
- Sea glass hunting
- Beginners
- Sea pottery
- Long beach walks
Seaham Hall Beach is the main event, the stretch of shore north of Seaham Harbour, where the majority of glass is found and where most hunters start and often finish their day. It lies below the headland where Seaham Hall Hotel stands, running for roughly a mile of mixed sand and pebble beach backed by low cliffs.
Where to look: Work the high-tide strandline first, this is where glass accumulates after storms and big tides, mixed in with pebbles, shells and coal fragments. Then move to the waterline as the tide ebbs, where freshly uncovered material is still wet and easier to spot. Clusters of pebbles trapped against rocks or the base of the cliff are always worth picking through. Crouch down and get your eye level close to the surface. Sea glass blends in with stones until you train your eye to recognise the frosted edges and smoother shapes.
Look carefully in rock pools at the lowest tides. Glass often gets trapped in pools and can sit undisturbed for weeks between spring tide exposures.
Access: The beach is accessed via a long staircase from the Seaham Hall Beach car park. This is not suitable for wheelchairs or buggies. The Vane Tempest car park end has easier, ramped access to the southern end of the beach.
Terrain: Easy- mixed pebble and sand beach, flat foreshore, no scrambling required.
Key Tip:
Start at the northern end of Seaham Hall Beach and work the high-tide strandline first before following the falling tide towards the waterline. Don’t rush. Seaham rewards slow, methodical searching, and many of the best finds are hiding in plain sight amongst the pebbles.
Difficulty Level – Beginner
- One of the most productive sea glass beaches in the UK
- Large hunting area with plenty of space to spread out
- Easy walking across a mix of sand and pebbles
- No scrambling or specialist equipment required
- Suitable for first-time hunters and families
Hunting Style – The Treasure Hunter
Seaham Hall Beach rewards patient hunters who are willing to slow down and scan carefully. Work the strandline after storms, check pebble concentrations around rocks and don’t ignore the waterline as the tide retreats. The beach produces finds throughout its length, making it ideal for a steady, methodical search rather than focusing on a single hotspot.
Beach Personality
This is the beach that put Seaham on the sea glass map. Generations of glassmaking history, combined with decades of wave action, have created one of Britain’s most famous hunting grounds. Despite its reputation, the beach rarely feels exhausted. Every visit carries the possibility of finding something unusual, whether that’s a beautifully frosted bottle fragment, a piece of pottery, or one of the rare coloured treasures that keep collectors coming back year after year.
Stop 2 — Blast Beach (Nose’s Point)
Best For:
- Sea glass hunting
- Storm hunting
- Sea pottery
- Sunderland history
Blast Beach is Seaham’s wilder sibling and a completely different experience. South of Seaham Harbour at Nose’s Point, this is where the former Dawdon Colliery once tipped industrial waste directly over the cliffs. The beach sits on the site of the former Dawdon Colliery, is more rugged and atmospheric, and produces glass finds too, especially after storms.
The beach features magnesian limestone rocks and boulders, iron oxide red mineral pools, sea glass, pottery shards, bricks and other industrial remnants. It has a genuinely alien quality: rust-coloured sand, dramatic limestone cliffs, rock caves at low tide, and a landscape that looks like nowhere else in England.
Blast Beach was famously used as the filming location for the opening scenes of Ridley Scott’s Alien 3. On a grey winter morning with the North Sea running, you’ll understand why they chose it.
For sea glass, focus on the pebble concentrations around the base of the cliffs and in the channels between limestone outcrops. Post-storm conditions here can be exceptional; the sheltered bay aspect means material gets deposited and stays put rather than being moved along the beach.
Key Tip:
Focus on the pebble pockets trapped between the limestone outcrops and around the base of the cliffs. Blast Beach often produces its best finds after strong easterly winds and winter storms when fresh material is uncovered.
Difficulty Level – Intermediate
- Uneven limestone terrain requires more careful footing
- Productive areas can be spread out across the beach
- Some hunting is best undertaken around lower tides
- Boulder fields and rock platforms can be slippery when wet
- More physically demanding than Seaham Hall Beach
Hunting Style – The Storm Chaser
Blast Beach rewards explorers who enjoy covering ground and investigating every pebble pocket, rock channel and sheltered corner. Rather than searching a single strandline, hunters should work methodically around the limestone features where glass and pottery become trapped between storms.
Beach Personality
Wild, dramatic and unlike almost anywhere else on the British coastline, Blast Beach feels more like an industrial archaeological site than a traditional seaside destination. Rust-coloured mineral deposits, towering limestone cliffs and remnants of the area’s mining past create a landscape with real character. For sea glass hunters, it offers a more rugged and adventurous experience than Seaham’s main beach, with the added thrill of never quite knowing what the next storm might reveal.
Access: The way down to the beach is steep, with steps available if you walk further along the clifftop, but these are still quite steep. Not suitable for wheelchairs, buggies or anyone with limited mobility. Allowing time getting down and back up is part of the commitment. Dogs on leads are advisable on the descent, given the steep cliff path.
Parking: Nose’s Point car park (SR7 7TT). Charges apply Monday to Sunday 8am to 6pm: up to one hour £1, one to two hours £2, over two hours £3.
Terrain: Difficult, steep cliff descent, uneven rocky foreshore, boulders to navigate at low tide. Rewarding but demanding.
Important: There are no public toilets at Blast Beach; the nearest are approximately 1km away in Seaham town centre. Check the tide before descending, the bay can cut off at higher tides.
Dog friendly?
A proposal to introduce a seasonal dog ban on Seaham’s beaches was put to public consultation in 2023, but was not implemented following a 1,240-name petition objecting to it. Both Seaham Hall Beach and Blast Beach remain dog-friendly all year round. Seaham is a dog-welcoming place; you’ll regularly see other dogs on the beach, and the promenade and harbour area have several dog-friendly cafés and pubs nearby.

What to bring
- Wellies or sturdy walking shoes – the beach is pebbly, and the Blast Beach descent requires grip
- A small container or zip-lock bag for your finds -one per stop if you’re doing both beaches
- A hand rake or garden trowel for turning pebbles at the strandline
- Layers – the North East coast is exposed, and the weather changes fast, even in summer
- A fully charged phone for tide times and photos – check before you leave for Blast Beach in particular
The history behind the glass
Seaham was the location of the largest glass bottle works in Britain, founded by John Candlish in 1853 under the patronage of the 4th Marquess of Londonderry, which operated until 1921. During nearly seventy years of production, waste glass was dumped directly into the sea – millions of bottles, jars, marbles and offcuts, along with the extraordinary end-of-day pieces formed when workers combined the last remnants of coloured glass at the close of each production shift.
That’s nearly seventy years of industrial waste, tumbled by North Sea tides into the extraordinary beach it is today. Every piece you find is a fragment of Victorian industry transformed by time and tide. The multi-coloured end-of-day glass is unique to Seaham and a handful of similar sites worldwide. If you find a swirling, layered piece with two or more distinct colours running through it, that’s a genuine Seaham special, irreplaceable and found nowhere else on earth.
Blast Beach has its own darker history. The former Dawdon Colliery tipped waste over the clifftops here for decades, and the site was once one of the most polluted beaches in Europe. A major restoration project transformed it over the last twenty years into the striking, otherworldly landscape it is today, an SSSI for both geology and rare wildflowers. The industrial remnants in the pebbles at Blast Beach, the pottery, the bricks, the glass, are what’s left of that history after the North Sea has had its way with them.
From beach to jewellery
Seaham is where sea glass hunting in the UK begins and ends. At Mermaid Tears, every piece of jewellery starts exactly where you’re standing. Seaglass is hand-hunted from UK beaches and handmade into something you’ll keep forever. The collection includes pieces made from Seaham glass in colours that simply don’t exist anywhere else. Browse the collection at mermaidtears.co.uk.

Frequently asked questions
Is Seaham Beach the best sea glass beach in the UK? Yes – it’s consistently rated as one of the finest sea glass beaches in the world. The volume and variety of glass, and the unique end-of-day multi-coloured pieces found nowhere else, put it in a category of its own.
What time is best to visit Seaham for sea glass? Arrive as the tide is going out, ideally after a storm or during a spring tide around full or new moon. Early morning, before other hunters arrive, gives you the best chance at undisturbed strandline material. Overcast days are easier for spotting glass than bright sunshine.
Is Seaham Beach dog-friendly? Yes – dogs are welcome at both Seaham Hall Beach and Blast Beach all year round. A proposed seasonal dog ban was rejected following a public petition in 2023.
What is Blast Beach, and is it worth visiting? Blast Beach is south of Seaham Harbour at Nose’s Point -a dramatically different and more rugged beach with a striking industrial landscape. The access is steep, and the terrain is difficult, but it produces glass finds, particularly after storms, and the scenery is unlike anything else on the Durham coast. Worth it for experienced hunters who want something different.
How much does parking cost at Seaham? The main seafront car parks charge up to one hour £1, one to two hours £2, over two hours £3 (Monday–Sunday 8am–6pm). A full-day £3 ticket is valid across multiple seafront car parks. Free parking is available in several town centre streets within walking distance of the beach. Parking is free at all sites between 6pm and 8am. Charges are subject to increase – check durham.gov.uk before visiting.
How rare is the multi-coloured glass at Seaham? Very. End-of-day glass is unique to Seaham and a handful of similar industrial beach sites worldwide. If you find a swirling multi-coloured piece with distinct colour layers running through it, that’s a genuine Seaham treasure that can’t be replicated anywhere else.
