Other travellers had warned me to be really careful with my camera in La Paz, which in general seams to have a bit dangerous reputation. We mostly walked here after dark, but everything went well, no problem. One whole day went in really high grounds, by the Ungas road, or better known as the Death Road, which is the world´s most dangerous - and probably most beautiful wountain biking road.
We got geared up really and started to get to know the very cool bikes w egot from the organizer, ProDownhill. It´s pretty important to be sure on this curvy road, that your bike has working brakes…because according to Wikipedia, there´s even today people getting killed on this road, even if cars are no longer allowed here.
But it´s all downhill, pure fun, pure speed - this is definitely one of the coolest adventures you can do in South America!!

Here´s more about the geography, history and statistics of the road: http://en.wikipedia.org/wiki/Yungas_Road
