Don't treat a trip to Auschwitz like you would a trip to any where else on the UNESCO list. this was a truly horrific journey and one which should not be taken lightly. the order of the Auschwitz complex and the sheer massive scale of Birkenau. The site achieves the utmost respect from every visitor. It is worth getting a guided tour as this gives much more information. Visits at different times of the year will give you a view of the different features of life in the camps from the bitter winter conditions to the blistering heat of summer. the station is Oswiecim and is on the line from Krakow, the main camp is a short walk/bus ride from the station and the birkenau complex is further out, best to have a short taxi ride. This is not a tourist destination and is geniunly the most Harrowing place imaginable.
