Porth Maenmelyn lies south of Strumble Head, and is mostly rocks and some dark sand. A small stream cascades over the rocks in the SE corner and the beach is backed by high cliffs of soft mudstones with a dolerite headland on the north side. Parking is at Pwll Deri (Grid Ref SM893386), with space for approximately 10 cars. From here take the coastal path northwards to its lowest point at the back of the beach. Access to the shore is down a steep, narrow path which was cut into the cliffside many years ago by a local resident. It has since become dangerous to use, and you should not attempt to visit this beach unless you are confident in your ability to reach it safely and to get off again.
From the coast path, a rough path 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. The handrail has long since disappeared, but the metal posts which held it are still in place, set in concrete. To minimise the risk of being splattered over the rocks below, a rope is required which can be attached to these posts.
'Porth Maenmelyn' translates as 'Yellow Stone Port'.
