Stac Biorach ( Scottish Gaelic: "the pointed stack") is a sea stack, 73 metres tall, situated between Hirta and Soay (in the "Sound of Soay") in the St Kilda archipelago of Scotland. It lies west of Stac Shoaigh (Soay Stac) (61 metres). [3]

The stack has never been inhabited, but has contributed considerably to the local economy by supplying the St Kildans with sea birds and their eggs. Rev. Neil MacKenzie, a Church of Scotland minister who resided on St Kilda from 1830 to 1844, observed the islanders collecting eggs from here in baskets like flat-bottomed bee hives, each basket holding about 400 eggs.[ citation needed]
Also known as "Thumb Stack" because the only holds on the rock are no bigger than a thumb [1] it is difficult to climb and "one which only a few of the natives could lead." [4] Quine (2000) describes the stack as "almost inaccessible" and adds that "even the St Kildans stopped climbing it around 1840". [5] [Note 1] Such was the remoteness of St Kilda from mainland Scotland that although described by Sir Robert Murray in the late 17th century, [1] [Note 2] Stac Biorach's exact location "remained a mystery" until Barrington's ascent in the late 19th century. [8]
Murray wrote that "after they landed, a man having room for but one of his feet, he must climb up 12 or 16 fathoms high. Then he comes to a place where having but room for his left foot and left hand, he must leap from thence to another place before him, which if hit right the rest of the ascent is easy... but if he misseth that footstep (as often times they do) he falls into the sea and the (boat's) company takes him in and he sits still until he is a little refreshed and then he tries it again, for everyone there is not able for that sport." [1]
Haswell-Smith states that landing is only possible on only three days in a summer month on average and that sailing the narrow channel betweem Stac Soay and Hirta is "possible in good weather". [1]
The first record of the recreational ascent of a sea stack in Scotland is likely that of Richard Barrington, [9] who climbed Stac Biorach in 1883. [6] An experienced alpinist, he called it the most dangerous climb he had ever undertaken. [10] [Note 3] He made the ascent with the help of two St Kildans, Donald McDonald and Donald McQueen. [6]
Today climbing in all of the St Kilda archipelago is subject to the permission of the National Trust for Scotland, [17] which rarely grants it. In 2023 a small group of British climbers, including Robbie Phillips from Edinburgh, completed the climb, the first documented ascent in 133 years. [13] Phillips said it "was like walking in the footsteps, or climbing in the fingerprints, of the St Kildans. It’s a testament to their bravery and mental fortitude; to climb onto that sea stack 70m above the raging Atlantic without even shoes is wild to imagine". [8]
Like the other islands in the St Kilda archipelago, Stac Biorach is extraordinarily rich in birdlife, and boasts the highest colony of guillemots in the archipelago. [18]
