Despite its vastness, it is still possible to tick off the highlights of Argentina at a leisurely pace during a three-week Argentina tour. Start with a sightseeing tour of Buenos Aires, where old-world charms survive among hulking neoclassical buildings. Then drive through the desolate rolling plains of Patagonia and cross the border into Chile where a surfeit of adventures awaits you at Torres del Paine. Back in Argentina, head for El Calafate to see the awe-inspiring Perito Moreno. To the north of El Calafate are El Chaltén, Argentina’s trekking capital and a starting point for those heading for the surrounding spires. End to your adventure in the vineyards of Mendoza, sipping glasses of exquisite, full-bodied malbec and gazing at the Andes in the distance. Not sure whether three weeks in Argentina is your thing? Not to worry because our guide on how many days to spend in Argentina has got you covered!

“The whole trip was excellent, I took part in both the Lima to Cuzco leg and again from Cafayate to Buenos Aires, and there were incredible opportunities during both legs. Personal highlights would be Machu Picchu, Arequipa, and the Estancia stay in Argentina.”
