There is a trip abroad that I'd like to do when COVID-19 allows us to travel freely again and if I have money to do so.
I want to visit the Argentine Northwest. There is a small city called Tolar Grande. From there you can visit Salar de Arizaro, the second largest salt flat in Argentina, where Cono de Arita is located. I also want to visit Iruya and some wineries in Cafayate. <<< Is Iruya and the wineries in Cafayate also in the Argentine Northwest? Who is your audience? I don't know where Cafayate is, but perhaps who you are writing this to does.
There are also other interesting places in the Argentine Northwest that I've visited before: Salta City, Quebrada de Humahuaca, Tilcara, Cachi, Quebrada de las Conchas, Purmamarca, Salinas Grandes (the largest salt flat in the country), Iruya, Cafayate, and Los Cardones National Park. Some of these places are located at more than 4,000 meters above sea level, in the Puna Area.
Because of its different landscapes, the Argentine Northwest is worth a visit once in your life. It's likely very different from places you have visited before.
