Despite the substantial distance (more than 240 km), the drive to the museum takes about 2.5 hours and is mostly by highway. Auschwitz was the largest German concentration camp during the Second World War. The camp has been preserved as museum and you can visit it individually or as part of group with a guide. Visiting the camp in a group tour takes about 4.0 hours, including the second part of the camp, Birkenau.
