Classic: Torres del Paine's W-Trek is a world-famous multi-day hike, with a trail that weaves through some of the most recognisable mountains on earth. Highlights include the mile-high granite towers and Lake Grey, peppered with icebergs that have plunged from the Grey Glacier. Accommodation is shared dormitory style refugios, and hiking is guided or self-guided.
Off-the-beaten-track: Camp among the mountains and step up to the more challenging Huemul Circuit. Leave the bustle of other hikers behind and head out into the silence of Los Glaciares, for beautiful views of the Patagonian ice cap, meadows, rocks, snow, wind, orange sunsets, sparkling mountain lakes, and even a zipline river crossing.
