Translation of hardened in German

I am Spanish Teacher. I graduated last year, in August. I studied mostly in Germany. I have been working for nine months as a teacher in many language schools but soon I will be a student again.
Our bus was completely full and we were the only Europeans on our tour. There were also Americans and people from South Korea. The driver took us to a place called Tam Coc. He drove like an idiot.
On day two my wife and I took a tour to visit the Altiplano. The tour started a little boring, when we visited a few empty villages nearby which were all pretty much the same. Empty with very little people.
