This first section of the path is attractive and low-lying.
Unfortunately at the current time of writing it is divided in two by the Alaw Estuary, which is wide and dangerous to cross on foot.

You can either do the walk in two halves; by walking the first half of the walk as far as Valley/Llanynghenedl and the second from Llanfachraeth to Porth Trwyn or catch a bus between Llanynghenedl and Llanfachraeth to complete the entire section in one go.
