Evening guys! I'm going on a RTW trip in November for 6 months and my final port of call will be South America. I've had my head stuck in guide books for months now and this is the only place I feel quite apprehensive about going. Is it a safe place for 2 women to be? Is it a safe place for any traveller to be? I don't mean to come across as being naive and ignorant, but would welcome some travel advice/some positive stories from people that have been. I'm so far taking in Santiago, Lima, Cusco (Inca Trail), Iguazu, Buenos Aires and Rio. Thanks!
