Cape Horn

Considered something of a Holy Grail for tourists – and the equivalent of Mount Everest for yachting types – and is well worth the effort, if not the bragging rights, if you can get there.

Cape Horn, the penultimate stop before Antarctica and the world's southernmost point, has long been renowned as a sailor's graveyard due to its isolation, perilous shoreline, and severe waves. While the Panama Canal has made it less essential as a trading route, it has grown in popularity among serious sailing aficionados and is included in a number of interesting races.

Cruise ships may be the greatest alternative. A lot of cruise ships sail by Cape Horn on their way to Antarctica and, weather and sea conditions allowing, will halt for an hour here. Passengers depart through inflatable boats, so this portion of the voyage can also be challenging.

Once onshore, passengers may make the short cliff-top trek to the Cape Horn Memorial Sculpture, which is possibly the ultimate tourist selfie site. This magnificent structure and its amazing vistas welcome you to the bottom of the planet.
