Around South America from Santiago to Buenos Aires

Santiago, is the capital and largest city of Chile as well as one of the largest cities in the Americas. It is the center of Chile's largest and most densely populated conurbation, the Santiago Metropolitan Region, whose total population is 7 million. The city is entirely located in the country's central valley. Most of the city lies between 500 m (1,640 ft) and 650 m (2,133 ft) above mean sea level.

Founded in 1541 by the Spanish conqueror Pedro de Valdivia, Santiago has been the capital city of Chile since colonial times. The city has a downtown core of 19th-century neoclassical architecture and winding side-streets, dotted by art deco, neo-gothic, and other styles. Santiago's cityscape is shaped by several stand-alone hills and the fast-flowing Mapocho River, lined by parks such as Parque Forestal. The Andes Mountains can be seen from most points in the city. These mountains contribute to a considerable smog problem, particularly during winter. The city outskirts are surrounded by vineyards and Santiago is within an hour of both the mountains and the Pacific Ocean.

Ushuaia is the capital of Tierra del Fuego, Antártida e Islas del Atlántico Sur Province, Argentina. It is commonly regarded as the southernmost city in the world. Ushuaia is located in a wide bay on the southern coast of Isla Grande de Tierra del Fuego, bounded on the north by the Martial mountain range, and on the south by the Beagle Channel. It is the only municipality in the Department of Ushuaia, which has an area of 9,390 km2 (3,625 sq mi). It was founded October 12 of 1884 by Augusto Lasserreand is located on the shores of the Beagle Channel surrounded by the mountain range of the Martial Glacier, in the Bay of Ushuaia. Besides being an administrative center, it is a light industrial port and tourist hub.

Cape Horn is the southernmost headland of the Tierra del Fuego archipelago of southern Chile, and is located on the small Hornos Island. Although not the most southerly point of South America (which are the Diego Ramírez Islands), Cape Horn marks the northern boundary of the Drake Passage and marks where the Atlantic and Pacific Oceans meet.

Cape Horn was discovered and first rounded in 1616 by the Dutchman Willem Schouten, who named it  Kaap Hoorn after the city of Hoorn in the Netherlands. For decades, Cape Horn was a major milestone on the clipper route, by which sailing ships carried trade around the world. The waters around Cape Horn are particularly hazardous, owing to strong winds, large waves, strong currents and icebergs; these dangers have made it notorious as a sailors' graveyard.

The need for boats and ships to round Cape Horn was greatly reduced by the opening of the Panama Canal in August 1914. However, sailing around the Cape Horn is still widely regarded as one of the major challenges in yachting. Thus a few recreational sailors continue to sail this route, sometimes as part of a circumnavigation of the globe. Almost all of these choose routes through the channels to the north of the Cape. (Many take a detour through the islands and anchor to wait for fair weather to visit Horn Island, or sail around it to replicate a rounding of this historic point.) Several prominent ocean yacht races, notably the Volvo Ocean Race, the VELUX 5 Oceans, and the Vendée Globe, sail around the world via the Horn. Speed records for round-the-world sailing are recognized for following this route.

It was also under brief British rule in 1807.
