When was the last time you sailed to the bottom of the world? Well, what if your next time — or first time — was on a cruise? Sail South America with Carnival and you'll get the chance to check out Cape Horn, the southernmost point anywhere in the Americas, located where Chile and Argentina border one another. This southern route around the continent was once a popular pathway for European-Asian trade (before the Panama Canal was completed, that is), but today is almost always chosen for its unique scenic quality… which actually hasn't changed at all since the olden days. Wildlife sightings at Cape Horn are always the highlight of the trip, with penguins, albatrosses, whales and sea lions calling the dramatic, rocky land and coastline home.
