Inaccessible Island

Saint Helena / Tristan da Cunha / Edinburgh /
 island, UNESCO World Heritage Site
Inaccessible Island is an extinct volcano, 14 km² (5.5 sq mi) in area, rising out of the South Atlantic Ocean 45 km (28 mi) southwest of Tristan da Cunha.

Inaccessible Island was first accessed in 1652 during a voyage by t'Nachtglas, a Dutch ship, 146 years after Tristan da Cunha was first sighted by Portuguese sailors. When mapped by sailors, the newly-found island was referred to as "inaccessible" since the crew who landed were not able to travel far into the island. Such challenges have persisted, but several expeditions have gone deeper into the island to uncover more details about its wildlife.

The island is a UNESCO World Heritage Site.
