Out Stack is the most northerly point of the United Kingdom, lying north of the Shetland Islands.Out Stack or The full stop at the end of Britain as it is called by VisitShetland is just what its name states: a stack, a rock.
Refering to it as an island within this context is simply due to the fact that it is the northernmost spot of land in the British Isles. Out Stack is not and never was inhabited.
It is lying some 600m to the north east of Muckle Flugga and about 1.6km true north of The Gord the most northern point of the island of Unst.
Out Stack lies within the boundaries of the Hermaness National Nature Reserve.
It is said that Lady Jane Franklin, the wife of the Arctic explorer Sir John Franklin landed on the Out Stack, after Dr John Rae's reports of the fate of the Franklin expedition had reached Stromness, Orkney, in 1853/54 where she lived in those days. Although she noted that she wanted to get as close as possible to her missing husband it must be doubted whether or not she landed on Out Stack. The fact that there was no safe landing was one reason - amongst other - why Thomas and David Stevenson decided later in the 1850s to build the lighthouse on Muckle Flugga and not on Out Stack.
Out Stack can be seen from the Smyril Line ferry, when it takes the northerly route past Shetland, traveling between Denmark, the Faroe Islands and Iceland.

From Out Stack you get a remarkable view of Muckle Flugga lighthouse, and the main Shetland isles in the background. Also, a great variety of seabirds nest on Out Stack,as you could imagine as it lies within the boundaries of the nature reserve, so birdwatching is a good thing to pass the time with.
With difficulty, as there is no means of communication on the island, and mobile phones don't work.
