Porth Maenmelyn lies south of Strumble Head, and is mostly rocks and some dark sand backed by high cliffs of Ordovician shales. Access is a steep, narrow path which was cut into the cliffs many years ago, and has since become very dangerous to use. Do not attempt to visit this beach unless you are absolutely certain you can do so safely.
A small parking area with space for approximately 10 cars is at Pwll Deri (Grid Ref : SM893386 / Lat : 52.0059°N, Lon : 5.0706°W). From here take the coastal path northwards to its lowest point behind the beach. A salebrous path then leads down to a narrow cutting through the side of the cliffs, beyond which the path is covered with piles of loose slate with sheer drops to the side. To minimise the risk of being splattered over the rocks below, a rope is required from this point.
