About Halen Môn
Halen Môn — "Anglesey Salt" — began in 1997 when David and Alison Lea-Wilson started producing sea salt from the waters of the Menai Strait at their home in Brynsiencyn. The clean, mineral-rich tidal water flowing through the narrow strait between Anglesey and the Welsh mainland proved ideal for sea salt production: drawn in, gently heated, and allowed to crystallise into white flakes with a pure, bright flavour. What began as an artisan experiment became one of Wales's most celebrated food brands, holding PDO (Protected Designation of Origin) status that formally recognises the unique provenance of the salt.
Halen Môn supplies some of Britain's best-known chefs and appears on restaurant tables and in kitchen stores internationally. The product range includes natural sea salt flakes, traditionally smoked versions, and seasonal flavoured salts. The Salt House at Brynsiencyn is the home of the operation — a converted building on the Menai shore that houses the production facility, a well-stocked shop, and a café where the salt seasons every dish. Guided tours of the salt-making process run regularly, offering a close look at how Menai water becomes table salt through evaporation and hand-harvesting.
The location combines well with a visit to the Anglesey Sea Zoo immediately next door — Wales's largest marine aquarium — and the beaches and forest of Newborough 4 miles south. Brynsiencyn is 4 miles from Menai Bridge and easily reached from the A4080 coastal road around southern Anglesey.

The Menai Strait — the narrow channel separating <span lang="cy">Anglesey</span> from the Welsh mainland — has clean, mineral-rich water that gives Halen Môn its flavour profile. The tidal currents through the strait maintain high water quality. The salt is produced in small batches with careful attention to crystal size and texture, resulting in delicate flakes that dissolve readily and season food without bitterness. Its PDO status is a formal recognition that the combination of location, water source, and production method cannot be replicated elsewhere.
The Halen Môn shop stocks the full product range: natural sea salt flakes, traditionally smoked sea salt, and a range of flavoured salts (including vanilla, seaweed, and seasonal varieties). Gift sets, recipe books, and Anglesey-themed gifts are also available. The products are sold in independent delis, farm shops, and specialist food retailers across the UK, but the best prices and widest selection are at The Salt House itself.
Brynsiencyn is a small village on the south coast of <span lang="cy">Anglesey</span>. The Anglesey Sea Zoo — Wales's largest marine aquarium, with native sea life including sharks, rays, lobsters, and seahorses — is immediately adjacent to The Salt House and can be combined easily with a visit. Newborough Beach and Llanddwyn Island are 4–5 miles south. Bryn Celli Ddu Neolithic passage tomb is 3 miles north-east.
