Tour begins: 2:00 PM, Hilton Buenos Aires. A transfer is included upon arrival at the Buenos Aires Ezeiza International Airport to the Hilton Buenos Aires. Your exploration of Buenos Aires begins this afternoon with a tour of the northern portion of the city. First, take the magnificent 9 de Julio Avenue and head north to the elegant neighborhoods of Palermo and Recoleta, with their wonderful parks and gardens, monuments and magnificent mansions. Then you'll visit the Recoleta Cemetery; established in 1822 as the first public cemetery in Buenos Aires, it became the final resting place for many of the city's elite in the 1870s. Walk around the majestic necropolis, which features over 47,000 ornate mausoleums, vaults, tombs and funeral monuments. Trace back the history of the country through the important figures interred here, from Remedios Escalada de San Martín to Eva Perón, whose mausoleum attracts pilgrims and visitors from all over the world. Return to the hotel for this evening's welcome reception and dinner featuring live music, tango dancers and lessons.

Your discovery of Buenos Aires continues today with more city sightseeing featuring the central and southern area. Your sightseeing today includes Buenos Aires' Main Square, Plaza de Mayo with its neo-classical Cathedral, colonial town-hall and the Presidential Palace, the "Casa Rosada." Then it's on to the old neighborhood of San Telmo with its narrow, cobbled-stone streets; and La Boca, home to multicolored tin houses and Buenos Aires' soccer stadium. Finally, experience the modernization of the city as you travel along Puerto Madero, and see its docks and large buildings presenting the latest architectural trends. (NOTE: Depending on traffic conditions and the day of the week, the Main Square may be visited on day 1 of the tour instead of day 2.) The remainder of the day is free for you to explore on your own.

Let your imagination soar as you fly down to Ushuaia, the southernmost point of South America, for the start of Tauck's 10-night Antarctica cruise. On-board amenities include all outside staterooms, two restaurants and lounges with evening entertainment, a fitness center, and multiple observation areas.

Find your sea legs on a two-day crossing of the Drake Passage, named after 16th-century explorer Sir Francis Drake who sailed these waters back in the late 1500s. While there is no land in sight during this part of your Antarctica cruise, you will have an opportunity to spot whales, dolphins and petrels from the observation decks of your yacht. You can attend on-board lectures from your naturalist team whose specialties include oceanography, ornithology and more. You may also take the time to visit the spa or the gym, curl up with a book from the ship's library or visit the bridge to chart your ship's progress.

One more day to go until you spot your first sight of the Antarctic Peninsula islands. Once part of a large Equatorial land mass, these islands broke off on their own more than 180 million years ago and are now home to glacial landscapes and wildlife that are awe-inspiring in every way. If you haven't yet watched one of the ship's collection of documentaries, today might be a good day to do so.

Wake up to a glacial wonderland. For the next four days, you'll be able to join an expedition team leader for a Zodiac excursion to any one of a number of Antarctic islands. Due to changing weather and shifting glacial patterns, your day-to-day itinerary will vary; each new day aboard this Antarctica cruise brings something different. Be on the lookout for seals on ice floes along the shore. Look up to spot seabirds flying against a cloudless blue sky. Look down in the waters where marine animals may be seen. At night, share stories during the daily cocktail hour and enjoy the camaraderie with fellow explorers.

If conditions permit, take a shore excursion to a polar village populated by fascinating and very amusing penguins. Walk softly among them on the beaches where their rookeries are found. See them waddle and wave as they make treks into the sea and back with food for themselves and their families. Your naturalist guide will share expert insights with you about these locals!

Dramatic icebergs, masterfully carved in all manner of shapes and sizes by the elements, don technicolor coats of blues, greens and snow whites and are the main event here in Antarctica. Get a closer look as you cruise among them and watch their transformation with the changing light of day. The sun never completely sets at this time of year so you can stroll on the deck late into the night and still enjoy an amazing glacial show.

By your fourth day cruising the Antarctic Archipelago, you may have passed by Penguin Island, blessed with diverse wildlife such as chinstrap and Adélie penguins, southern giant petrels, Antarctic terns and skuas, and Hannah Point, one of the best places to see gentoo and macaroni penguins, blue-eyed shags, and Wilson's storm petrels, with the occasional fur seal or elephant seal among them. Don't worry if their names sound confusing; you will soon become a pro at identifying them with some help from your on-board ornithologists.

The wildlife experts on your ship are eager to point out the region's fur seals and elephant seals who share the frigid waters with penguins and humpback whales. You may find a fur seal or two languidly sunning or sleeping on ice floes, their faces endearing with natural smiles, in large part because there are few native predators like polar bears here. Southern elephant seals, so named for their massive sizes and trunk-like noses of the males, prefer to hang out in beach parties; look for them on rocky island shores. As your captain skillfully navigates your yacht around Lemaire Channel, you'll have a good chance to see humpback whales, always a breathtaking sight. The evening colors are spectacular too!

Your ship begins its voyage back through the Drake Passage today,making it the perfect time to record the experiences you had during thepast week. Your private ship log might include your thoughts about the array of icebergs and the Swedish expeditioners' hut you saw in HopeBay, or the old whaling station you encountered near Neptune's Bellowsand that dip you were tempted to make in the hot geothermal springsthere. You may have had an opportunity to meet the researchers and scientists of KingGeorge Island or explore the history of Elephant Island, linked toErnest Shackleton and his men. Your stories will make great reading back home!

Savor your last day of your Antarctica cruise as you cross the Drake Passage again. Activities include on-board lectures that enrich your new-found knowledge; spa treatments that keep you relaxed and refreshed; work-out equipment that invigorates; and card games or chess tournaments with shipmates. Your last evening aboard ship is a perfect time to toast your expedition, and celebrate what for many travelers is their "seventh continent."

Your Antarctica cruise ends when you disembark ship today in Ushuaia for your flight back to Buenos Aires. A transfer to Buenos Aires' (Ezeiza) Ministro Pistarini International Airport is included. Tour ends: 6:00 PM, Buenos Aires' (Ezeiza) Ministro Pistarini International Airport. You should allow three hours for flight check-in.
