Porth Wen is a beach of mostly shingle backed by steep bracken covered banks, with rocks and rockpools at low tide. On the western side of the bay is a derelict brick works which can be reached along the shore or from the coastal path. Just beyond this is a natural rock arch and a small harbour from where the bricks were exported. On the eastern side of the bay in a zawn near the headland is a small copper mine, about 50 yards in length. Access to the beach is a steep path down the bank, which is likely to be extremely slippery in wet conditions.
There is space for 2 or 3 vehicles to park on the sloping verge at Grid Ref: SH398942, from where a public footpath (the one on the right) leads down to the coastal path behind the beach. Further parking can be found on lay-bys a little further away near the junction with the A5025.
