where is salt marsh filmed

Under Salt Marsh (often shortened to Salt Marsh) is filmed across several real locations in north and west Wales, with the fictional town of Morfa Halen created from a blend of these places.

Main filming locations

• Barmouth, Gwynedd – This seaside town and the Mawddach Estuary provide the primary backdrop for Morfa Halen, including many seafront and town scenes.

• Fairbourne, near Barmouth – The salt marsh and coastal village shots, including promenades and residential streets, were largely filmed in Fairbourne.

• Shell Island / Llanbedr – Used for the causeway and marshland vibe that inspired the idea of a town at the end of a tidal route across the salt marshes.

• Anglesey (Ynys Môn) – Key locations include Newborough Forest, Aberffraw, Malltraeth, and Menai Bridge, which provide dunes, coastline, and village scenery for Morfa Halen.

• Cardiff (studio and set work) – Some marsh and town elements, especially complex marsh sequences, were built and shot around Cardiff.

So, if you’re asking “where is Salt Marsh filmed?”, the answer is: it’s mainly shot around Barmouth and Fairbourne in north‑west Wales , with additional scenes in Anglesey, Llanbedr/Shell Island, and Cardiff standing in for the fictional town of Morfa Halen.

TL;DR:
Salt Marsh’s fictional town, Morfa Halen, is not a real place – it’s stitched together from real Welsh locations like Barmouth, Fairbourne, Shell Island/Llanbedr, Newborough Forest and villages on Anglesey, plus some work in Cardiff.
