Hi Everyone! My husband and I are planning a major tour of some areas of Argentina ... we have never been here before. One of the areas we'd like to tour is the Northwest ...Cafayate, Salta, etc. Right now we're thinking of flying into Salta from BA and then renting a car. Does anyone have a 5-7 day itinerary to suggest? Also do we have to be prepared for possible altitude sickness? Any and all suggestions would be most appreciated! Thanks very much!
