Why Marsden is the most historically significant sea glass beach in the North East
Most people know about Seaham. Fewer people know the story behind Marsden, which is a shame, because in terms of industrial glass history, South Shields makes Seaham look like a late arrival.
Glass-making in South Shields dated back to the 17th century, introduced by Huguenot exiles escaping religious persecution in France. By the early 1800s, South Shields was one of the largest glass-making centres in the country, with eight large glassworks operating in the town. In 1827, about two-fifths of all English glass was made in the Tyneside area. By 1845, South Shields was making more plate glass than anywhere else in England.
The glass produced here, crown glass, plate glass, flint glass, bottle glass, supplied the whole of southern and eastern England. The whole of southern and eastern England received consignments of glass from South Shields, with about 60 per cent of the trade going through a London warehouse.
All of that industrial activity sat directly on the River Tyne, less than two miles from the Tyne mouth. And at the Tyne mouth, the North Sea takes over. Marsden Bay sits immediately south of the river entrance on the same magnesian limestone coast positioned to receive exactly what the Tyne and two centuries of glass manufacturing put into these waters.
Marsden Beach is backed by tall, dramatic cliffs, featuring some of the most striking rock formations on the Northeast coast, including sea stacks, rock arches and the famous 30-metre Marsden Rock. Built into the cliff face is Marsden Grotto — one of only two cave bars in Europe, hewn from the rock at a time when smugglers worked this shore.
It’s one of the most atmospheric beaches in the North East, and the sea glass story here is one of the best in the country.
What you’ll find here
Colours commonly found: Green, white, brown
Occasional finds: Blue, Aqua, Amber, Turquoise
Rare finds: Cobalt Blue, Black, Lavender, Red
Bonus: Littlehaven Beach at the mouth of the Tyne, a short walk north, is also cited by local collectors as a productive location given its position right at the river mouth. Including both beaches in a single visit maximises the hunting area considerably.
The caves accessible at low tide around Marsden Rock are worth exploring; glass accumulates in the sheltered cave floors between tides.
When to go
Marsden faces east into the North Sea, the same aspect as Seaham and the Durham Heritage Coast immediately south. The same rules apply: post-storm conditions after a northeasterly or easterly blow, spring tides, arrive on the ebb. The tidal range at the Tyne mouth runs to around 4.5 metres on a spring tide, providing generous exposure that reveals the rock pools, cave entrances and lower cliff base sections where glass concentrates.
At low tide it is possible to walk out to Marsden Rock itself and explore the caves. These cave sections are the most sheltered and least picked-over sections of the beach; glass deposited there sits undisturbed between tides. Low tide access to the caves is the Marsden experience that casual visitors miss entirely.
Winter is the prime season for North Sea storms, empty beaches, and full tidal access. Marsden hosts the largest seabird colony in the North East of England, with kittiwakes, cormorants, fulmars and razorbills on the cliffs year-round, making an autumn or winter visit a genuine wildlife experience alongside the glass hunt.
Today’s tide times & Sea Glass Score
Marsden Bay faces east into the North Sea, immediately south of the River Tyne mouth on the magnesian limestone coast of South Tyneside. The tidal range here runs to around 4–4.5 metres on a spring tide, enough to expose the rock pool sections, cave entrances and lower cliff base areas where glass concentrates most reliably. The tidal pattern is semi-diurnal with two highs and two lows per day.
The widget below uses River Tyne (North Shields) tide data, the nearest UKHO standard port, to show today’s Sea Glass Score, tide curve and best hunting window. Aim to arrive on an ebbing tide and time your visit to the Marsden Rock caves within an hour of low water access, as the tide turns.
Where to look on the beach
The beach is both pebbly and sandy, backed by tall limestone cliffs with rock formations including sea stacks and arches. For sea glass, there are three distinct zones:
The main bay strandline -work the high-tide strandline from the cliff lift southward. Glass accumulates here after any significant North Sea swell, mixed in with the pebble and shell debris that collects along the wrack line. Post-storm is when this section is most productive.
The rock pool sections – the rocky areas around the base of the cliffs and between the stacks produce the most consistent glass. Work the pebble pockets between rock formations carefully; glass concentrates in the same channels that trap driftwood and heavier debris. Wet pebbles at the waterline are far easier to read than dry ones further up the beach.
Marsden Rock and the caves – at low tide, walk out to the rock itself and explore the cave entrances in the cliff base. Legends of smugglers, wrecks and colourful characters surround these caves and glass that washes into the caves sits undisturbed in the sheltered cave floors between spring tides. These sections are least picked over and most likely to produce older, better-tumbled pieces.
Key Tip:
Time your visit for low tide and make a beeline for Marsden Rock and the cave entrances. These sheltered areas receive far less attention than the main beach and can hold older, beautifully frosted pieces that have remained protected from casual collectors.
Difficulty Level: Intermediate
- Some of the best hunting areas are only accessible at low tide
- Rocky sections require careful footing, especially when wet
- Accessing caves and rock formations requires good timing
- Productive hunting grounds are spread across several different habitats
- Tide awareness is important to maximise your hunting window
Hunting Style: The Cave Explorer
Marsden rewards hunters who venture beyond the obvious. Search the strandline first, then move into the rocky channels, pebble pockets and cave entrances revealed at low tide. The most interesting finds are often tucked away in sheltered corners that many visitors overlook.
Beach Personality
Marsden feels wild, dramatic and full of secrets. Towering limestone cliffs, sea caves and the iconic Marsden Rock create one of the most atmospheric hunting locations on the North East coast. It’s the sort of beach where every rock formation seems to hide another crevice worth checking, and every low tide reveals new ground to explore. The combination of history, geology, and constantly shifting coastal conditions makes every visit feel like a genuine treasure hunt.
Dog friendly?
Dogs are allowed on Marsden Beach throughout the year with no seasonal restrictions. While the summer dog ban applies at Sandhaven Beach to the north, Marsden Beach has unrestricted access all year round. Your dog has the full beach at any time of year, including the cave sections at low tide.
Souter Lighthouse, a 15-minute walk south along the coast path, is also dog-friendly and well worth including on any visit. The coastal path between Marsden and Souter is one of the better cliff walks in the North East.

Practical information
Parking: Pay-for parking is available along the A183 Coast Road National Trust car park, free for members; charges apply to non-members. The postcode NE34 7BS brings you to the beach access point. Arrive early on summer weekends as the car park fills quickly.
Access to the beach: A long set of steep wooden steps leads down the cliffs, or alternatively, a lift is available for which a voluntary donation is requested. The lift is operated by the Marsden Grotto. Factor the climb back up into your timing; it’s demanding after a long session on the beach.
Toilets: Public toilets are available at the beach.
Food and drink: Marsden Grotto is literally carved out of the rock face and accessed by the cliff lift, one of the most extraordinary pub locations in England. It serves food and drinks throughout the day. Colman’s Seafood Temple in South Shields is a Northeast institution for fish and chips and is a 10-minute drive north.
Getting there without a car: The nearest Metro station is South Shields, with the E1 bus from South Shields to Sunderland stopping at Marsden Bay. South Shields Metro station is on the Tyne and Wear Metro network from Newcastle.
Accessibility: The cliff lift provides access to the beach for those who cannot manage the steps; a voluntary donation is requested for its use. The beach itself is mixed sand and pebble with uneven sections around the rock formations.
What to bring
- Sturdy footwear with grip – the rock pool sections and cave approaches are slippery, especially when wet
- A torch for the caves at low tide – the cave interiors are dark and worth exploring carefully
- A small container for finds – the cave sections may produce older and more unusual pieces
- Layers – the cliff-backed beach creates its own wind channelling effect, and the North Sea air arrives with intent
- A tide table – cave access closes quickly; check the window before heading out to the rock
The history behind the glass
The glass story at Marsden begins not on the beach but in the town two miles to the north. The first glasshouse at South Shields was established around 1707. By 1737, the Cookson family, who would become the dominant glassmakers of the Northeast, had set up their crown and plate glass works on the Tyne, with the whole of southern and eastern England receiving consignments from their works.
Glass-making had been introduced to South Shields in the 17th century by Huguenot exiles fleeing persecution in France, skilled craftsmen who brought Continental techniques to a town perfectly positioned for the industry: coal for the furnaces, the Tyne for transport, and the North Sea for disposal of waste. By 1827, two-fifths of all English glass was made on Tyneside. By 1845, South Shields was making more plate glass than anywhere else in England.
Among the last of the great South Shields glassmakers was Edward Moore, whose Tyne Flint Glass Works produced extraordinary Victorian pressed glass until the works finally closed in 1913. The works used a ballast wagonway to take waste material directly to the coast. The glass from two centuries of production, crown glass, plate glass, flint glass, bottle glass, pressed glass, entered the Tyne and the North Sea in quantities that dwarf most other UK glass beach sources outside of Seaham itself.
Marsden Bay itself has its own darker history. The limestone caves in the cliff face were the haunt of smugglers for centuries. The ghost of John the Jibber, who was suspended in a bucket halfway down the cliff after betraying his fellow smugglers to the customs men, is said to haunt the Grotto to this day. The smuggling trade brought its own glass to these shores: Dutch gin jars, French brandy bottles, spirit flasks from across the Channel. Every era of this coast’s history has contributed to what the North Sea returns to the beach today.
From beach to jewellery
Marsden glass carries the history of the glass capital of England, two centuries of industrial production that supplied the whole country, tumbled by North Sea tides in the shadow of the cliffs where smugglers once worked. At Mermaid Tears, every piece of jewellery starts exactly where you’ve been standing, hand-hunted from UK coastlines and made into something lasting. Browse the collection.

Frequently asked questions
Is Marsden Beach good for sea glass? Yes – it’s a consistent Good Beach with a glass origin story that rivals any beach in the UK. The eight South Shields glassworks that supplied two fifths of all English glass by 1827 sat two miles from this beach on the Tyne, and the North Sea has been returning their output ever since. The cave sections at low tide are the most productive and least picked-over areas.
What is the history of glassmaking at South Shields? South Shields was one of the most important glass manufacturing centres in England for over two centuries, beginning with Huguenot craftsmen in the 17th century. By the early 1800s, the town had eight large glassworks; by 1845, it was making more plate glass than anywhere else in England. The glass from these works entered the Tyne and the North Sea in enormous quantities and is still being returned to Marsden Bay today.
Are dogs allowed at Marsden Beach? Yes -dogs are welcome all year round with no seasonal restrictions. Marsden is one of the few South Tyneside beaches exempt from the summer dog ban that applies to Sandhaven.
Can I visit the caves at Marsden Rock? Yes – at low tide, it’s possible to walk out to Marsden Rock and explore the cave entrances in the cliff base. Always check tide times before heading out, as access closes quickly. Bring a torch, the cave interiors are dark and worth exploring carefully for glass trapped in sheltered corners.
How do I get to Marsden Beach without a car? Take the Tyne and Wear Metro to South Shields station, then the E1 bus towards Sunderland, which stops at Marsden Bay. South Shields Metro station is on the Yellow Line from Newcastle city centre.
What is the Marsden Grotto? The Marsden Grotto is a pub and restaurant literally carved out of the limestone cliff face above the beach, accessed by a cliff lift. It’s one of only two cave bars in Europe and has been serving the beach since the 18th century, originally a haunt of smugglers, now a very good place for a post-hunt meal. The cliff lift is a voluntary donation and also provides beach access for those who can’t manage the wooden steps.
