In the heart of the summer season, we visited Argentina to review hotels in Buenos Aires, its beguiling capital city. After a few days there, we flew to Argentine Patagonia to review two new properties, one in El Calafate and the other in the climbing mecca of El Chaltén. Rugged and remote, this area of South America was every bit as beautiful as we had imagined, and we took in its glacial scenery aboard a boat, on horseback and while hiking. Until recently, intrepid travelers with a taste for luxury would opt for the Chilean side, but Argentine Patagonia is catching up, offering plush lodgings in which to unwind after trekking, climbing and sightseeing.
