...for 7 hours. After a brilliant days horse riding, including a large amount of galloping, my back hurt rather a lot. The next day we decided to an 'easier' trek - turned out we ascended 1300m and walked about 24k in total. It was a great walk though, we visited an abandoned mine on the way up, and all this was thanks to our fantastic guide Elvio, and the stunning scenery around the tiny Andean village of Uspallata, where were staying. All in all a fantastic, exhausting few days!
