To go by car and bus from Ciudad Valles, San Luis Potosi to the city Guanajuato in the state of Guanajuato (shortened GTO) took a whole day even I did not have long waiting times. The trip was worth it. Unfortunately I have so far only put in the text for my first day here, photos will be added soon. To read about GTO, you can follow the link for Guanajuato.
I also have updated my report about all of my destinations in the state of San Luis Potosi and added photos. Meanwhile you are waiting for the photos for GTO, you can read about the days before by following the link to SLP.
Enjoy and stay tuned, please!
