A coastal walk around the cliffs of Loughshinny

The famous folding cliffs of Loughshinny which we have all seen in our Geography books in school are formed by layers of limestone and shale, which have been folded into angular layers. The layered rocks buckled to form the folds we can now see. Take a walk with me and the dog along the cliff trail.

Loughshinny is a small seaside village in between Skerries and Rush. The village has lots of history and they’ve designed three walks which are 3.5km each and broken into sections so you can do as many as you want depending on physical fitness.

The famous cliffs of Loughshinny which we have all seen in our Geography books in school are formed by layers of limestone and shale, which have been folded into angular layers. The fossils in the rocks – corals, brachiopods and goniatiles, a species characteristic of the Carboniferous period are approximately 325 million years old. At the time the area that is now Loughshinny was probably the floor of a tropical sea. The sea floor was continuously subsiding so that the rocks now seen in the cliffs were buried by many hundreds of younger rocks. About approximately 290 million years ago subsidence stopped and the rock pile was subjected to horizontal compression. The layered rocks buckled to form the folds we can now see. Subsequent uplift has brought the folded limestone and shale to the surface.
