South Stack, Holyhead

South Stack sits at the wild north-western tip of Holy Island, where a whitewashed lighthouse clings to a rock stack below dramatic quartzite cliffs. It is one of Anglesey's most photographed spots, and from the clifftop above Ellin's Tower the views along the Irish Sea and back toward Holyhead Mountain are superb. For pilots this is spectacular but sensitive terrain. The cliffs are an RSPB reserve and internationally important for breeding seabirds - guillemots, razorbills and puffins - so flying anywhere near the colony between roughly April and July is strongly discouraged and can disturb protected wildlife. Come in autumn or winter, launch well back from the cliff edge, and keep clear of the lighthouse and visitor buildings. The site is comfortably outside the RAF Valley flight restriction zone, which lies about twelve kilometres south-east, but fast military jets do transit this coast at low level, so stay alert and keep your drone low. Sea breezes funnel hard around the headland and lift near the cliff face, so expect turbulence. Fly early on a settled morning for the cleanest air and softest light on the stack.
