Magilligan Point

Magilligan Point is best appreciated from the air (see link below). It is a large cuspate foreland with an amazing series of beach ridges. Parallel ridges document the building of the feature; truncation of the ridges, particularly near the tip, document erosion. These patterns tell the story of changes in sea level, changes in sediment supply, and simply the accumulation and rearrangement of material over thousand of years. It's among the larger depositional coastal features in Ireland and also has a large dune system.


The landform defines the entrance to Lough Foyle, which is the estuary of the River Foyle (which flows through Derry).

We drove across it, but my only exposure to the beach itself was at the very tip of the spit, a short crossing from Donegal's Inishowen Peninsula (at least it would have been a short crossing, had the ferry not broken down, leaving us to drive around).
