Given that Abancay is a 14-17 hour bus ride from Ayacucho, and our previous Andes bus experience was less than desirable, we opted for an overnight stop in Andahuaylas. The bus (Expreso Los Chankas 25 PEN/CAD$8.80) to Andahuaylas was eleven hard hours on unpaved winding mountain roads.
While the motion sickness/soroche didn’t raise its ugly head again (thank Science!), I cannot stress how tiring and soul consuming an eleven hour bus ride through the Andes on an unpaved road is. There were several moments of teeth clenching as the bus swerved around precipitous curves, but for the most part the driver seemed cautious and drove at a good speed. The majority of buses that leave for these treks through the Andes leave at night and there are rumours (and crosses at the side of the road as a testament) that buses regularly veer off the edge of the cliffs.
