Merthyr Mawr Sand Dunes are situated about one mile outside the village of Merthyr Mawr; they are a huge network of dunes, rolling over towards the Ogmore/Porthcawl coast, and once the largest sand dune system in Europe. The dunes also claim fame to the highest single sand dune in Europe, known locally as the 'big dipper'. The dunes are very popular with kids, runners and local wildlife enthusiasts. Scenes from the famous film Lawrence of Arabia were filmed at the dunes.
