Island Antarctic island in the South Shetland Islands
Greenwich Island in the South Shetland archipelago draws Antarctic cruises for landing beaches, penguin and seal colonies and stark polar shorelines viewed from expedition boats.
Greenwich Island is one of the South Shetland Islands in Antarctica, situated off the northern tip of the Antarctic Peninsula. The island is largely ice-covered with areas of exposed rock and coastal bays.
