Why Boulmer is Northumberland’s best-kept secret
People ask me which Northumberland beach to go to for sea glass. I tell them Boulmer every time, and they always come back with a haul.
Boulmer, pronounced “Boomer,” in case the locals look at you sideways, is one of the last true fishing villages on the Northumberland coast. Forget the wide tourist-friendly sandy beaches that stretch from here to Bamburgh.
Boulmer is different. It sits in a natural gap in the sandstone reef, a bowl-shaped haven where the North Sea funnels in and deposits whatever it’s been carrying. The beach is a mixture of sand, pebbles, and exposed rock, with pools and reef edges at low tide, everything a sea glass hunter wants to see.
This isn’t a beach that gets cleaned up and smoothed over for summer visitors. The seaweed, the rocks, the barnacled ledges it all looks a bit chaotic compared to the polished holiday beaches nearby.
That chaos is exactly what you’re looking for. Glass hides in the crevices, collects behind reef edges, and turns up in the pebble ridges that form between the tide lines. You don’t come to Boulmer for a sunbathe. You come here because you’ve heard things wash up here that don’t wash up anywhere else on this coast.
The village is compact a row of fishermen’s cottages, the Fishing Boat Inn, and a car park. Blue fishing cobles are still hauled up the beach by tractor, just as they have been for a hundred years. If you arrive early in the morning when the cobles are going out, you’ll feel like you’ve stepped back in time.
And you’ll probably have the beach to yourself.
What you’ll find here
Colours commonly found: Green, brown, white
Occasional finds: Blue, Aqua, Amber
Rare finds: Turquoise, Cobalt Blue, Black, Pink
Bonus: Pottery shards, old clay pipe fragments, smooth pebbles, occasional driftwood
When to go
Boulmer is a tide-sensitive beach. The rocks and reef platforms only emerge properly on a low spring tide, those are the days when the beach transforms into something genuinely exciting.
The difference between a neap low and a spring low here is significant: the reef sections that are usually underwater come out, and with them comes glass that hasn’t seen daylight in weeks.
Winter is the right season. September through March brings north-easterly storms that churn glass off the seabed and pile it against the reef edges. The beach after a blow is a different proposition entirely from a calm summer day. Summer is fine, but the beach has usually been well-worked by other hunters by then.
Aim for the hour either side of low water. Get there before high tide starts to flood back. The rock pools and reef edges are your targets. Run your eye along the base of any exposed sandstone ledge, and you’re likely to spot something.
Difficulty Level
Intermediate → Advanced
Not because it’s dangerous in normal conditions, but because:
- timing is everything here
- productive areas vanish at higher tides
- reef terrain is uneven/slippery
- success depends heavily on weather + tide knowledge
This is a beach where:
the conditions matter as much as the location.
Hunting Style
“Condition-Based Reef Hunting”
Meaning:
- plan around tides first
- weather second
- beach third
This isn’t really a “pop down for 20 minutes” beach.
The best hunters here are probably:
- checking tide charts
- watching wind direction
- arriving after north-easterlies
- timing visits around spring lows
Today’s tide times & Sea Glass Score
Boulmer sits on the North Sea, directly exposed to the north-east, with a tidal range of around 4.5 metres on a spring tide, which is a generous range that exposes a substantial reef and foreshore as the water drops. The difference between a spring low and a neap low here is immediately visible: at spring tides, wide platforms of wave-cut sandstone come clear of the water, revealing the crevices and channels where glass collects.
The widget below uses Amble tide data (the nearest UKHO primary port, approximately 7 miles south) to show today’s Sea Glass Score, tide curve and best hunting window. Aim to arrive 90 minutes before low water on a spring tide the bigger the range, the more foreshore you get, and the more glass you’ll find along the reef edges.
Where to look on the beach
Boulmer Haven is the main focal point of the natural gap in the reef where the fishing cobles are launched. The beach spreads north and south from here.
North of the haven, the rocks begin to take over from sand, and the reef becomes more pronounced. Walk this section at low tide and look along the base of any exposed rock ledges. Glass gets caught in narrow channels between rocks and behind small ridges of pebble that build up during storms. This is where your better pieces are most likely to be.
South of the haven towards Seaton Point: a longer stretch of mixed sand and pebble. Check the strandline carefully after a storm glass travels this way from southward drift. Pebble banks that form after rough weather are worth turning over by hand.
The pools: at spring low tide, rock pools form across the reef. Don’t just look in the water, look at the rocky margins of each pool. Pebble-sized glass pieces collect where the pool edge meets loose stone.
Key Tip
At Boulmer, don’t judge the beach on a single visit. The difference between a calm summer neap tide and a winter spring low after a north-easterly storm is massive, the reef platforms completely change what’s accessible and where glass settles.
A note on safety: the rocks at Boulmer are covered in weed and slippery at all states of the tide. Wear boots with grip, flat shoes, or trainers, as they are a genuine hazard here. The reef can also cut you off if you wander too far out and the tide turns quickly. Know where low water is before you go, watch the tide, and don’t take risks chasing a find on a falling ledge.
Dog friendly?
Yes- Boulmer is dog friendly all year round, no seasonal restrictions. It’s a popular spot with local dog walkers precisely because it’s never been overrun with beach-ban byelaws. Your dog has run these rocks more than once, and the combination of rock pools, seaweed to investigate, and the general chaos of a working beach keeps dogs thoroughly entertained.
Keep dogs under close control on the rocky sections. The weed-covered reef is slippery for four paws and two feet alike. On the sandy sections north and south of the village, dogs can run freely.
For dog-friendly places to eat and drink nearby, check the Yappy Places listing for Boulmer and Alnmouth, the Fishing Boat Inn itself is your best bet in the village.
Practical information
Parking: The Beach View car park in Boulmer (NE66 3BS) has recently been taken over by Northumberland County Council, and charging has been introduced in line with other coastal sites in the region. Charges are pay and display, verify current rates before you go, as these are newly implemented. Some roadside parking remains available in the village, though double yellow lines restrict the most convenient spots.
Toilets: Public toilets are available in the village, a short walk from the beach.
Food and drink: The Fishing Boat Inn is the only option in Boulmer itself, a well-regarded pub with sea views from the terrace, local crab and lobster when available, and a warm welcome. For more choice, Alnmouth (3 miles south) has several cafes and pubs.
Getting there without a car: Boulmer is genuinely difficult to reach without a car. A limited bus service (Arriva X18/418) connects Boulmer to Alnwick and the surrounding villages, but services are infrequent. Check Traveline Northeast before visiting.
Accessibility: The car park gives reasonable flat access to the immediate beach area. The rocky sections north and south of the haven involve uneven terrain and are not accessible for wheelchairs or those with limited mobility.
What to bring
- Sturdy wellies or walking boots with grip – non-negotiable on this beach
- A hand rake or small trowel for working pebble ridges
- A small container or zip-lock bags for your finds
- Layers – Boulmer is exposed, and the wind off the North Sea bites even in summer
- A tide table checked in advance (not just a quick glance at the clock)
- Dog towel if your dog’s coming – those rock pools are irresistible
The history behind the glass
Boulmer’s glass comes from centuries of maritime life on one of Northumberland’s most active stretches of coast. This was never a pleasure beach it was a working village, a fishing station, and for a significant period of its history, the smuggling capital of Northumberland.
In the 18th and 19th centuries, contraband goods from the Netherlands, France, and Scotland – gin, spirits, salt, and tobacco were landed at Boulmer under cover of darkness, with the Fishing Boat Inn serving as the headquarters of the operation.
Ships arriving and departing in those conditions didn’t worry much about what went overboard. Combined with the everyday debris of a working fishing community – bottles, jars, glass floats, ship’s lanterns, centuries of material have entered the water off this coast.
The name Boulmer itself carries echoes of that maritime past, with roots possibly going as far back as old French “boul de mer,” sea bowl, a description of the village’s natural arc of sheltered water. Whatever the name’s origin, the bowl shape has been catching things from the sea for a very long time.
RAF Boulmer was established here during the Second World War, and the base remains active today. That wartime presence brought another wave of material to this stretch of coast. Some of the older, thicker pieces you find here have that dark olive patina of pre-war glass- keep an eye out for those.

Frequently asked questions
Is Boulmer good for sea glass beginners? Yes- but manage your expectations on a first visit. Boulmer rewards those who know what they’re looking for and where to look. The rocky sections at low spring tide are where the glass concentrates. A calm sunny August afternoon won’t give you what a January morning after a storm will.
How do you pronounce Boulmer? “Boomer.” Locals will know you’re new if you say it any other way.
Is Boulmer Beach dog-friendly? Yes, all year round. No seasonal restrictions apply.
What’s the best time to visit Boulmer for sea glass? Autumn through winter, on a low spring tide, ideally in the day or two after a north-easterly storm. Arrive 90 minutes before low water. Morning visits mean less competition.
Why is there no harbour at Boulmer? Boulmer is unusual among fishing villages in having no formal harbour, boats are simply launched off the beach and hauled back up by tractor. The natural gap in the reef provides some shelter, but there’s nothing man-made. This is part of what keeps it so raw and unchanged compared to other coastal villages.
Can I find rare glass at Boulmer? Black (pirate) glass from old rum and spirit bottles turns up here more than at most beaches a legacy of the smuggling trade. Red is rare but possible. Cobalt blue is the find that will make your day.
