My husband I are planning a trip to Argentina for around 9 days in the beginning of March 07. We want to see BA and Iguacu, but also some of the interior. Salta seems very appealing. Question:What is the Calchaquies Valley and how is it different from the Huahuaca Gorge? How hot and rainy will it be at that time of year? (Fodors guidebook talks about washed out roads in summer.) Does the Gorge come before or after Purmamarca (heading out from Salta)? Purmamarca sounds very interesting (especially the Paso de Siete Colores), but so does Cayafate(in the opposite direction). We don't want to spend all our time in the car. We would probably stay 3 days - any itinerary ideas would be appreciated. We are upscale travelers. Also, what are the altitudes there? Can you see any of the Andes? Would we be better off going to Mendoza or Corboda instead at that time of year?
