New Zealand is the closest country to the south pole. Thus, the international team of scientists that study the continent of Antarctica takes off from New Zealand whenever they go to the coldest continent.
Bluff is the southernmost point of the South Island, where one can take a ferry to Stewart Island, which is colder than most parts of New Zealand and affords the visitor a sneak preview of the climate in Antarctica.
I wanted to visit Stewart Island, but because the ferry has only one trip a week, the trip was aborted. Nonetheless, I found a spot where one could see Stewart Island from across the channel, with a signpost that reminds one how far away are the largest cities in the world.
