Antarctica

There are 2 ways to Antarctica:  air and sea. Air travel is shorter but very unreliable due to weather conditions.  The preferred route is to take a 11+ day cruise across the Drake Passage.  The sea is very rough and I recommend taking medication if you have sea sickness.

The starting point is Ushuaia which is on the southern tip of Argentina and Chile.  It is a 2+ day to reach the northern tip of Antarctica.

Attached is a map and some interesting photos.
