Ayacucho Transportation: 2 reviews and 1 photos
Ayacucho to/from Andahuaylas = 10 hours and 25 soles no paved roads at all. Bus company is Los Chankas. Take warm clothes and a good book (and your camera at the ready because the scenery is very beautiful)
Ayacucho to/from Lima = in 2005 you could do most of the distance on the Lima-Cusco bus. You'll have to get off the bus in the middle of nowhere and take a cab/collectivo for the rest of the trip. I think I have read somewhere that there is now a bus lima-Ayacucho so check other tips and search the web/guide books!
