⛰️ Stac Biorach

Stac Biorach is a sea stack, 73 metres (240 ft) tall, situated in the Sound of Soay between the islands of Hirta and Soay in the St Kilda archipelago of Scotland. It lies west of the 62 metres (203 ft) high Stac Shoaigh. Regarded by the St Kildans as the most challenging of their stacks to climb, it was nonetheless an important source of food. The first written records date from the second half of the 17th century and the first recreational ascent took place in 1883. It is now part of the St Kilda World Heritage Site and in the care of the National Trust for Scotland.
