This rather dilapidated-looking Pile Light is situated off Magilligan Point at the eastern entrance to the River Foyle, reached from Castlerock (previous entry) by a very scenic drive which is spoiled somewhat 0.5 miles from the Point by the appearance of the completely unattractive Magilligan Prison.
There is a Martello Tower at the point, a pub and a few holiday homes. There are views of Inishowen Head Lighthouse, Warren Point and Moville, all on or near the far coast in the Republic.
The light itself is Q.R. 7m 4M and marks the eastern extremity of the navigable channel through the entrance of the Foyle. 55° 11.730´N, 006° 58.055´W
