Under Salt Marsh is set in the fictional town of Morfa Halen. The story takes place in a coastal Welsh community shaped by harsh weather and marshland terrain. While the town is not real, the series was filmed across several real locations in Wales. The landscape plays a major role in the mood of the show and influences how the story unfolds.
The production team focused on coastal areas where nature feels unpredictable and powerful. Much of the filming took place in North Wales, with additional work completed in Cardiff.
Barmouth
Barmouth served as one of the primary filming locations for the series. The seaside town sits along the Mawddach estuary and offers wide views of beaches and mountains. The town helped shape the visual identity of Morfa Halen.
Its waterfront streets and surrounding marshland areas were used to create the small town setting seen throughout the show. The natural coastline and tidal environment helped reinforce the sense of isolation shown in the story.
Fairbourne
Fairbourne was another key filming location. The village sits on low lying coastal land and is often associated with discussions about rising sea levels. This made it a fitting backdrop for a story centered around environmental danger and flooding risk.
Scenes featuring coastal tension and community gatherings were filmed here. The landscape reflects the vulnerability that runs through the series narrative.
Anglesey
Filming also took place in Anglesey. The island is known for its rugged coastline and tidal marshes. These areas helped create the dramatic natural environment shown in the series.
Many wide exterior shots showing open coastal terrain were filmed here. The location helped show how exposed the town feels to weather and sea conditions.
Cardiff
Some scenes were filmed in Cardiff where production teams built indoor sets. The final episode required a large marsh environment that could not be safely filmed outdoors. The team constructed a controlled marsh set inside a studio to film complex scenes involving extreme weather.
Cardiff provided technical production support while location shooting remained centered in North Wales.
How The Landscape Influenced The Series
The salt marshes of North Wales inspired the story itself. Creator Claire Oakley wanted the environment to feel central to the narrative. The coastal wetlands are fragile ecosystems that protect land from flooding and absorb large amounts of carbon.
The show reflects the danger of building communities near vulnerable coastlines. The incoming storm in the story mirrors real environmental concerns faced by coastal Welsh towns.
The remote locations also shaped performances. Cast members spent extended time living near the filming areas which helped them connect with the setting and atmosphere of the story.
Is Morfa Halen A Real Place
Morfa Halen is not a real town. The fictional location was created using elements from several Welsh coastal communities. The production team combined features from Barmouth, Fairbourne, Anglesey, and nearby landscapes to build the town shown in the series.
The goal was to create a place that felt authentic while allowing creative freedom for storytelling.
