Potosi is a city that you can not stay at without getting to know. If you hang out for a walk in Bolivia, the most common thing is to get there after touring the Salar de Uyuni, which is next to the border with Chile, and there is a majestic corner, however there are many options to get to this lovely city. This Bolivian city became one of the world's richest city due to its hill "Cerro Rico" which is full of minerals like gold and silver through the years and to date is still being exploited as a source of employment for many natives. The architecture is also one of the great things, you can find many structures and churches.
The city of Tarija is located the south of Bolivia. Here you'll find a pleasant climate and very hospitable and friendly people. I got to know it while I was traveling and loved it! I hope to one day go and live in Tarija. The city is quite cozy.
