Argentina stretches from subtropical falls at Iguazu to Patagonian glaciers, and the distances between them are continental. Buenos Aires is the starting point for most trips, with its European-influenced architecture and neighbourhood-based character, and the rest of the country is reached by air.
The guides here cover Buenos Aires and Argentina overall. Seasons are reversed from the northern hemisphere: Patagonia is accessible roughly November to March, while the north is more comfortable in the cooler months. Argentina's currency and pricing have been unstable for years, with exchange arrangements changing frequently — worth checking close to departure rather than relying on older advice.
