Once a popular haunt for smugglers, Cwmtydu is now a small cove owned by the National Trust. It is made up of coarse sand and shingle backed by a concrete sea wall, with the Afon Ffynon Ddewi emerging onto the beach on the south side. There are rockpools and caves at low tide. Free roadside parking overlooks the beach with a private car park about 100 yards away. An old lime kiln is on the sea front, behind the car park. Other facilities here include toilets, 2 cycle stands, a cafe and a B&B. Dogs are allowed at all times.
