Eldey

Background

History & Background

Eldey's geological history is rooted in volcanic activity, as it is formed from móberg (palagonite tuff). This dramatic rock island is part of a larger submerged volcanic ridge and a cluster of skerries known as Fuglasker or Eldeyjar, which extends far into the Atlantic from the Reykjanes Peninsula. The island holds a poignant place in natural history. Not far from Eldey, another skerry called Geirfuglasker served as the final stronghold for the Great Auk, a flightless seabird. Tragically, this skerry largely sank during volcanic eruptions in 1830, contributing to the ultimate extinction of the species. Eldey itself has long been a critical sanctuary for various seabirds. Today, Eldey is primarily known as the site of the largest Northern Gannet colony globally. Historical counts, such as one conducted in 1949, estimated the gannet population at approximately 70,000 birds. The island is a protected nature reserve, ensuring the continued prosperity of this magnificent bird colony, and its inaccessibility helps preserve its pristine environment.

Eldey, meaning "Fire Island," is a towering, uninhabited rock island located approximately 15 kilometers south of the Reykjanes Peninsula's southwestern tip. This dramatic sea stack, rising 77 meters above sea level, is a geological marvel formed from palagonite tuff (móberg). Its most astonishing feature, however, is its vibrant ecosystem. Eldey is renowned for hosting the largest Northern Gannet colony in the world. As seen in the image, its every available ledge and crevice is teeming with countless white-feathered gannets, creating a breathtaking visual spectacle against the dark, rugged cliffs. A constant flurry of birds circles the island, their distinctive calls echoing across the waves. Eldey is part of a larger cluster of skerries known as Fuglasker or Eldeyjar, stretching 45 nautical miles from the mainland. Historically, this area held immense significance for birdlife; one of these skerries, Geirfuglasker, was the last known breeding ground for the Great Auk before it largely sank in volcanic activity in 1830. Today, Eldey stands as a protected nature reserve, safeguarding its immense gannet population, which numbered around 70,000 birds in a 1949 count. Due to its protected status and challenging terrain, the island is inaccessible, and visitors must admire its wild beauty and the majestic birdlife from a respectful distance, typically via boat tours from nearby harbors. Observing this natural wonder from the sea offers an unforgettable glimpse into Iceland's untamed wildlife.
