The walk starts at Pwll Deri, a popular beauty spot bounded by cliffs rising to over 130 metres described as the perfect rural retreat, it has a car park, youth hostel and camping site. You will pass Aber Mawr, an important geological site with the cliffs revealing a sequence of deposits from the last ice age. There is also a submerged forest, however beware of erosion, rock-falls and subsidence on this section of path. The walk ends at Abercastle, a small harbour with a Neolithic burial chamber at Carreg Sampson just inland from the coast-path. The harbour was also the landing site of the first single handed atlantic sailing west to east in 1876 starting from Gloucester, Massachusetts by the Danish born fisherman, Alfred "Centennial" Johnson.
