We were very lucky to have found David Martinez to show us areas of Salta Province on the road north of Salta city. Watching the scenery unfold on the road through the rain forest and desert on the way to Purmamarca, David was full of information and appreciation for the landscape and the people. We continued on to Salinas through remarkable scenery. David is an excellent driver, and made sure we were comfortable at the high altitudes. David knows the best places to pull off the road for photos, and even helped us take some entertaining shots on the salt flats. He knows very good places to stop for meals too.
In Tilcara, David's explanations were thorough, and he answered many, many questions. We continued on through the area called Painter's Palette and to the Tropic of Capricorn. All through the route we had interesting conversations and listed to the music of the region.
Before you travel to Salta, you could consult David about places to stay overnight, and you could trust his judgement.
Don't forget to appreciate the sky throughout your tour!
