Between it and Yell are a mini-archipelago of small islands including Linga, Sound Gruney, Urie Lingey, Daaey and Wedder Holm.
Unfortunately, their return was marred by a strong storm, and eventually they found their tiny boat blown to Karmøy in south west Norway.
[1][2] Haaf Gruney is used as a setting in the 2014 novel The Sixteen Trees of the Somme (Svøm med dem som drunker) by Norwegian author Lars Mytting.
Haaf Gruney is a national nature reserve for the storm petrels which breed there.
The islet is no longer used for grazing, but there are marine Eurasian otters living here, and the usual seals.
