Most Antarctic cruises follow the same route: an international flight to Buenos Aires, 1 or 2 nights in the city, a flight to Ushuaia, and boarding. It's a 48-hour window in one of the most fascinating cities in the world — and most passengers waste it in the hotel or wandering aimlessly around downtown.

This guide is written specifically for you: the traveler heading to Antarctica but with Buenos Aires right in front of them. You'll come back from Antarctica transformed. Make the most of what Buenos Aires has to offer too.

Buenos Aires has more theaters per capita than any city in the world, a food scene that rivals the best in Latin America, neighborhoods with more history than many European capitals, and a tango culture found nowhere else on the planet.

We're not suggesting a full tourist circuit. We're saying that with 2 well-used nights you can leave with a vivid, authentic picture of the porteño city that will perfectly complement the polar experience ahead.

The 4-hour private tour with DePasseios covers the neighborhoods that resonate most with a curious traveler: Recoleta with its European architecture and South America's most famous cemetery, San Telmo with its 19th-century colonial market, La Boca with its street art and port history, and Puerto Madero with its modern skyline on the riverfront.

The tour includes private transport from your hotel, a bilingual guide with deep historical knowledge, and the ability to adjust the route in real time. Price from USD 120 per group.

Palermo Soho in the afternoon is a full sensory experience: independent bookstores, artisanal ice-cream shops, local design stores, and plazas where porteños gather at the end of the day. It's the everyday version of Buenos Aires that doesn't appear in guidebooks.

A traveler heading to Antarctica who doesn't see tango in Buenos Aires is missing half of Argentina's cultural journey. Tango Porteño is the city's most acclaimed show: live orchestra, professional dancers, dinner included, and authentic staging. DePasseios arranges the show with transfer included from your hotel.

Ushuaia has good polar-gear suppliers, but prices are considerably higher than in Buenos Aires. Things worth buying or completing before flying south: mid layers, quality waterproof gloves, SPF 50+ sunscreen (UV radiation in the far south is extreme), motion-sickness medication (highly recommended for the Drake Passage), and boots with good soles if your cruise includes zodiac landings.

The flight from Aeroparque (AEP) to Ushuaia takes about 3 hours. It's a scenic flight: Patagonia from the air is already the start of the experience. Aerolíneas Argentinas and LATAM operate this route several times a day.
