This sprawling, beguilingly wild region long ago grabbed us and never let go. We’re intimate with the best-known places, passionately experienced guides, and hardest-to-reach corners of South America’s outback. Walk beside the shockingly blue lakes of Torres del Paine and the Fitz Roys, or range farther afoot to little-visited Aysen Glacier, even sail around Cape Horn to utterly remote Tierra del Fuego. Stay at luxury estancias serving fabulous food and wine, or rough it on a fully guided trek.
