This is confusing so extra attention is needed. I wanted to go to San Isidro in Salta. In order to do so I needed to go to Humahuaca (Jujuy) first and take a bus to Iruya (Salta) and then walk over 10 km (or 6.21 miles according to the converter) to go to San Isidro (Salta), which is at about 4000 m above sea level (or 13.123 feet according to the converter).
From the salt flats to Humahuaca. Done. From Humahuaca to Iruya. Not done because there are only two buses in the morning. A night in Humahuaca was mandatory. Not a big deal, it´s a beautiful town.
First things first, I looked for a place to sleep and went straight to Churita´s house (a lovely woman I had met years ago that rented beds for the night) but she wasn´t in. So I ended up in a nice hostel where I took a long and well deserved shower. I was salt-free.
I went to walk around and when my stomach was growling, I came back to the hostel. There were two girls talking to the receptionist, asking about Iruya. I joined them offering all the information I had gathered at the terminal and we ended up having pizza at the hostel´s restaurant. The receptionist was the cook so after being served, he sat at our table together with a couple from New Zealand and an Argentinean guy that had met them on the road. A crowded table, lots of stories were shared, we had a good laugh while having beer.
The following morning I woke up early, had my breakfast and went for a short walk before hopping on another bus. A girl that was having breakfast too asked me if she could come with me and we went around taking pictures while sharing travel tips.
Long story short, all of us went to Iruya together. We should have rented a private truck !! It was really fun.
