Inaccessible Island

Inaccessible Island is a small, uninhabited volcanic island in the South Atlantic, administered as part of the Tristan da Cunha group and noted for its wildlife conservation significance.

The island supports dense seabird colonies and relatively undisturbed native vegetation; there are no permanent settlements and visitor facilities are absent. Its remoteness and lack of safe harbour make landings difficult and infrequent.

Long visited by sailors and later subject to occasional scientific expeditions, the island has been managed for conservation in the modern era and is grouped with Gough Island as a World Heritage site for its intact bird populations.

Located roughly 400-500 kilometres south of Tristan da Cunha’s main island in the South Atlantic, Inaccessible Island lies far from major landmasses and is reachable only by sea on occasional expeditions.

• Size and Conservation Status: The island covers roughly 14.5 square kilometres and is uninhabited; it is part of the British Overseas Territory of Tristan da Cunha and is a UNESCO World Heritage component for its seabird colonies.
• Access Restrictions: Landing is strictly limited and usually permitted only for scientific or conservation missions; there are no harbours and access is by small boat from offshore.
