My parents ( late 50's) and I (late 20's) are planning a 5 weeks trip to South America. We will be spending 7 nights (6 full days) in the Salta region in late May. We will be arriving in Salta late after noon from Buenos Aires and are planning to stay the night in Salta. On day 2 we are planning to rent a car for the rest of our time in the area. We would appreciate any advice/suggestions regarding the best routes we should follow and how many nights to spend in each place.
Thank you all in advance.
