About this stretch of coast
Magilligan Point guards the narrow mouth of Lough Foyle, where the lough drains into the Atlantic opposite Greencastle in Co Donegal. The point is the tip of one of the largest sand dune systems in the British Isles, and the inside shore you walk along is a National Nature Reserve, prized for its seabirds and for the migrating waders and wildfowl that crowd the mudflats in winter.
The squat Martello tower at the point was built around 1812 to 1817, during the Napoleonic Wars, to guard against a French invasion. It is one of the northernmost of the 74 such towers built around the coasts of Ireland, and it still stands well preserved at the start of the walk.
From here the shore runs unbroken for miles, linking Magilligan with Benone Strand and Downhill beach, seven uninterrupted miles of sand backed by dunes and, further along, the cliffs and clifftop temple at Downhill.
