The fame of Argentina is usually linked to tango and gauchos, but many travelers are especially attracted by its natural wonders ranging from the deserts of North cordillera of the Andes and the southern and desolated beautiful landscapes of Patagonia. In this extreme land i decided, with Alexander, to make my first (and so far only) raid in MTB. Descriptions of estasiate Chatwin have influenced me greatly in the choice of my first great adventure on two wheels, although the wide-open and "free" spaces have always exerted a strong attraction to a "enclosed" like me (living in the middle of the Alps, great for other reasons, infinite horizons are not very familiar to me!). By planning the trip, we realized how depopulated Patagonia is, especially in the central area where the Pampa dominate. The first idea was to go to the largely mythical "ruta 40", which crosses the Argentina from north to south, crosing the border to Chile for a few days on the equally famous " Carretera Austral." In fact, reaching the town of Perito Moreno, we opted for a detour on the Atlantic coast, renouncing the MTB partially because of prohibitive weather conditions (the trip was made in October, early spring) and the desire to dwell more in the "Parque Los Glaciares National "for a few days of trekking to Cerro Torre and Fitz Roy, mythical mountains for us Trentino. The last day of travel also, as expected were spent in Buenos Aires in order to visit the cordialissimi and hospitable relatives Ale.
