20-night Antarctica

This expensive trip-of-a-life-time sails round-trip out of Ushuaia, Argentina, and explores all three of Antarctica’s main regions — the Antarctica Peninsula for its stunning icebergs and penguins; South Georgia Island to follow in the footsteps of explorer Ernest Shackleton; and the pastoral Falkland Islands. 

When to Go: December

Why Then: Penguin chicks start hatching during this time of the year, when Antarctica sees the most sunlight (20 hours per day) and the warmest temperatures of the year.
