St Kilda is a truly superlative archipelago. Europe’s most inaccessible UNESCO World Heritage Site, the archipelago emerges from the waves at the far west of the Outer Hebrides. Its vertiginous sea cliffs tower over 300 metres tall, the highest in the United Kingdom, and serve as a refuge for the largest bird sanctuary in the North Atlantic. This site is as fascinating for the colonies of northern gannets, petrels and Atlantic puffins as it is for the incredible story of the “bird fishers” who survived on this rocky outcrop, barely 9 km², for millennia until they themselves asked to be evacuated in 1930. The touching ruins of their dwellings are still visible near the shore.
