Great to do something different
We did a half day tour. The bikes were great and in excellent condition. We were very satisfied with Francisco, our guide. He was flexible in changing the path to be as easy or challenging as we’d like and incorporating specific sites we were interested in seeing. During the path itself (yugos tour) you won't see amazing sites as in other places of 
Salta. But we want it to do something different, a bit of exercises. It was great for that. Furthermore, Francisco was very knowledgeable about Salta and was able to answer all of our questions; about the history, nature and attractions in the region.
