The Cerro Madsen hike, in the Mount Fitz Roy area near El Chalten, is a perfect challenge for keen hikers who want to summit a mountain in Patagonia and treat themselves to one of the most wonderful views in the world. This 21 kilometre challenging day hike is led by a professional mountain guide, who will help you safely ascend the Madsen summit, which reaches 1715 metres above sea level. The views over Los Glaciares National Park from the top are spectacular, with glacial lakes, jagged peaks and valleys as far as the clouds will let you see.
