"Antarctica’s most popular tourist destination is a unique British post office located in the heart of the Antarctic Peninsula at Port Lockroy, about 700 miles south of Argentina and Chile," the episode description for "Penguin Post Office" reads. "Enthusiastic cruise ship passengers from around the world come ashore throughout the Antarctic summer to see the colony of 3,000 gentoo penguins that takes up residence each year alongside Port Lockroy’s other summer inhabitants – the post office staff."
