15 Night Cruise sailing from Valparaiso to Buenos Aires aboard Seabourn Sojourn.

The second of Seabourn's new class of ships, Seabourn Sojourn, was also built at T. Mariotti yard in Genoa. Her debut was on June 6, 2010 in the middle of the River Thames in London. Seabourn Sojourn's godmother was the English fashion icon and actress Twiggy. Like her sisters, Seabourn Sojourn enchants her guests with an array of public areas scaled to encourage a relaxed sociability. One of the most unusual features of Seabourn Sojourn and her sisters is Seabourn Square, an ingenious "living room" that replaces the traditional cruise ship lobby with a welcoming lounge filled with easy chairs, sofas and cocktail tables.

Highlights of this cruise:

Valparaiso
Picturesque Valparaiso was one of the first Chilean cities founded by the Spanish. The city is an historic port and university town, famous for its labyrinth hills, which are covered in quaint, colorful old houses and accessible only by a steep climb or by the city's unique system of funicular railways. Through the efforts of the Chilean government emphasizing the city's culture, heritage preservation, and economic development via tourism, Valparaiso was bestowed designation as a World Heritage Site by UNESCO in 2003.

Puerto Montt
The lake country of southern Chile seems to be altogether another world from the deserts of the north. The Lake District is graced with spectacular scenery, including the magnificent snowcapped volcanic cone, Mt. Osorno. Puerto Montt serves as the principal port for this region and as a gateway for cruises southward into Chile's fjords.

Punta Arenas
Red roofs and smoking chimneys decorate the gently sloping hillsides of Punta Arenas (Sandy Point), the bustling center of one of the world's largest sheep farming areas. This pleasant community welcomes you with attractive parks and delightful Victorian architecture.

Ushuaia
The southernmost city in the world, Ushuaia is the capital of Argentine Tierra del Fuego and an important naval base boasting a strategic as well as a picturesque location on the shores of Ushuaia Bay and the Beagle Channel. This rustic coastal town is set among waterfalls, glaciers, snow-clad mountains and beech forests, and the nutrient-rich local waters abound with marine life. Though the houses here are painted warm, pastel colors, the weather is chilly year-round and winter sports such as downhill and cross-country skiing and skating are popular. Ushuaia's principal industries are raising sheep, logging, fishing and trapping. It became a boomtown with 30,000 residents in the late 1980's when the government sought to increase Argentina's presence near Antarctica by giving tax breaks to citizens who settled here.

Montevideo
Tucked in between Brazil and Argentina, the republic of Uruguay has nevertheless maintained its own identity and traditions. As South America's second smallest country, it has been called a city surrounded by a big ranch. Montevideo has also been referred to as "The Switzerland of South America," for its same secretive bank system guaranteed by law. Uruguay is principally middle class and boasts the most highly educated citizens on the continent.

Buenos Aires
Founded in 1536, Buenos Aires was administered by a Spanish viceroy for nearly three centuries before winning its independence in 1816. A sleepy port town for most of that time, it wasn't until the turn of the 20th century that the city finally emerged as an important shipping center. Today, Argentina's democratically elected government has made it South America's safest (and most expensive) country. This cosmopolitan city is characterized by broad boulevards with huge shade trees, beautiful residential districts, plazas containing monuments and fountains, interspersed with 20th-century high-rise buildings. It is a truly great walking city.
