La Paz is not just the largest, but also the most important city of Bolivia. La Paz City tours take you to the most interesting places in downtown: the San Pedro Prison, the Witches Market, and several museums. La Paz is a top destination when it comes to cultural trips: travel to Tiwanaku, of to the village of Viacha where they can learn how to dye wool. However, La Paz offers far more than cultural tours. Have you ever heard of the Death Road, the most dangerous road frequently cruised by mountain bikers?
