Cnoc Glas

Rising to 517 metres on the uninhabited island of Soay in the St Kilda archipelago, this modest summit sits in one of Britain's most remote locations. The island lies 65 kilometres west of the Outer Hebrides, accessible only by charter boat in calm weather, making any ascent a genuine expedition.

• •The name Soay derives from Old Norse 'Sauðey', meaning 'island of sheep', reflecting the Viking presence in these waters over a millennium ago.
• •Soay is home to a unique primitive breed of sheep that has lived wild on the island for centuries, smaller and darker than domestic breeds and considered one of Britain's oldest surviving sheep types.
• •Excluding the isolated rock of Rockall, Soay marks the westernmost point of the United Kingdom, further west than any other permanently mapped feature in the realm.
• •The island forms part of the St Kilda World Heritage Site, designated for both its natural heritage and the remarkable story of the archipelago's former human inhabitants who evacuated neighbouring Hirta in 1930.
• •Access to Soay requires crossing some of Britain's most challenging waters, with the island receiving fewer visitors in a year than Ben Nevis sees on a busy summer's day.
