I would like to go from Puno, Peru to Arica, Chile. I have looked and looked online and cannot seem to find a reliable bus company. Are there buses from Puno to Arica? If not, which bus companies go from Puno to Tacna? And how do I get from Tacna to Arica? I am going this June (2014). Anyone have any recommendations of reliable and safe bus companies from Puno to Tacna or Arica? Any help is greatly appreciated!
