From 12 to 14 April 2006 I followed an old Inca path in Bolivia: El Choro. This Inca path starts at "La Cumbre", the top, in the Andean mountains at something like 4.700 meters above sea level.
The path ends three days later at Chairo (1.200 m), where you hire a car for a one hour ride to the popular site Coroico.
My guide was Luis Muñoz, who knows this mountains inside out. It is a very hard trip, and I made it thanks to his advise and support.
