Main image

Boreray is an uninhabited island in the St Kilda archipelago off the northwest coast of Scotland and forms part of the St Kilda World Heritage Site. The island is rugged and dominated by steep cliffs that provide nesting sites for large seabird colonies.

Key features include cliff-nesting seabird populations and offshore stacks that are used by gannets, fulmars and other species; the island offers no visitor facilities and landings are irregular. Visitors, when permitted, come for wildlife observation and specialist guided trips.

Boreray has a history of seasonal human use in the past but has been uninhabited in modern times; its value today is primarily ecological, as part of the protected St Kilda group.

The island lies north of the main St Kilda island of Hirta in the Outer Hebrides, exposed to Atlantic weather and accessible only by boat when sea conditions allow.

  • Access and protection: Part of the St Kilda World Heritage Site and National Nature Reserve - access is by boat from Hirta and landings are weather-dependent.
  • Wildlife importance: Important seabird habitat with large colonies of gannets and other sea birds; the island is uninhabited and visited mainly by specialist tours and researchers.
