Merthyr Mawr Sand Dunes
About
The Merthyr Mawr Sand Dunes form part of the Merthyr Mawr Warren National Nature Reserve in Bridgend County, Wales. Located just west of the Ewenny River, this dune system is a unique coastal landscape and the highest in Wales, rising to up to 15 m above sea level. The reserve is a haven for wildlife, hosting species such as hedgehogs, badgers, and a variety of amphibians and birds, including the kingfisher and wet‑land specialists. Ecology is a major highlight of the dunes. The varied coastal habitats support rare plant communities such as dune grassland, saltmarsh, and sea‑spray meadows. Species including sea kale, wild carrot and sea beet thrive in the stiff, saline environment. The combination of open sandy slopes and sheltered coves creates a mosaic of niches that attract both seen and elusive wildlife. Archaeology adds another layer of interest. The dune complex covers Neolithic long barrows, Bronze Age round barrows and early historic sites, many of which are now buried beneath the shifting sands. Walkers can follow marked paths to view surface cairns, stone buttons and other indicators of past settlement, offering a tangible link to the region’s ancient history.
