This photo was taken on the Lleyn Peninsula (Penrhyn Llŷn in Welsh).
Llŷn is notable for its large number of protected sites — including a National Nature Reserve at Cors Geirch, a National Heritage Coastline and a European Marine Special Area of Conservation as well as twenty Sites of Special Scientific Interest.
The Llŷn Coastal Path, a long distance footpath, enables walkers to fully explore both coasts of the peninsula.
Much of the coastline and the ex-volcanic hills are part of the Llŷn Area of Outstanding Natural Beauty, confirming the peninsula as one of the most scientifically important in both Wales and Britain. In 1984 there was an earthquake beneath the peninsula, which measured 5.4 on the Richter Scale and was felt in many parts of Ireland and western Britain.
