I´m mountaineering some in Cordon del Plata at the moment. Will cycle north from Mendoza soon. Planned departure date about the 25`th of March. I will use small roads and I will climb a lot of mountains along the way. If you feel like going into the outback of Argentina (and later Bolivia, Peru etc.) and have some stops for trekking and climbing along the way drop me a line.
I`ll probably stay in Hostel Independencia in central Mendoza, close to Plaza de Armas.

I´ve cycled a lot before, in about 60 countries on all continents. My preference is always to stay off the main roads (I hate the panamericana) and I try to stay close to the mountains.
