I visited this WHS in September 2014. This is one of the most touching and horrific WHS I've been too and it definitely deserves its place on the list for mankind to be aware that such atrocities should have never happened in the past and mustn't occur in the future. It is now possible to visit Auschwitz individually only from 08:00-10:00 and 16:00-18:00. Otherwise you'll have to visit with another 25-40 people on a guided visit. Since this WHS isn't an attraction but a site to experience, I believe that the best way to visit is in silence and in touch with your inner self. I arrived in Oswiecim around 8am and there were some parked cars already in front of the Auschwitz museum. However, the place is huge and being able to visit individually means that most of the time you're alone in each section. By the time the group visits start, you'll have to queue to even enter a section which doesn't make sense to me personally. The most shocking experience to me was to see the room with plaits and shaved hair. As the first groups started to flock in, I proceeded to the exit and drove to Brzezinka to visit Auschwitz II Birkenau. This site covers an incredible surface area where unspeakable horrors took place. The gate to hell and railways are worth visiting to experience the sheer size of this place. I'm glad I visited this WHS. Even though we've read, listened, seen quite a lot about the scourge of these concentration camps, we have possibly got used to hearing about it and therefore might not be shocked anymore. Visiting this WHS will definitely be a shocking experience and rightly so.
