On the way to La Paz we passed lots of small run down villages and huts, they were all full of people, the passing cars and lorries were rammed full of people and it seemed like a very busy place. I could see La Paz in the distance, it looked unbelievable, a big city in the middle of a valley, it was quite literally like a city built in an upside down bowl, with houses going right up the edges. La Paz itself is the highest city in the world, ranging from 3200m to about 3700m depending on where you are in the city. It looked very cool indeed, something I had never seen before and didn't have anything remotely close to compare it to.
