They are both next to each other in Krakow.

Trains to Oswiecim (the town where Auschwitz is located) leave every couple of hours. From there the camp is within walking distance. Buses also leave every hour or two for the trip. It will take approximately one and one-half to two hours to reach the camp.

Additionally, there are a number of independent buses (airport shuttle bus-type) that make the trip. They tend to collect tourists in the parking lot in front of the bus terminal in Krakow.

Make sure you give yourself enough time. There are actually two camps at Auschwitz, separated by about two miles. There is a free shuttle bus that runs between the two camps. The first camp that you will see is the one with the infamous "Work will set you free" sign on the entrance. Many of the housing units have been converted into museums, and it will take you a while to visit.

I found the second camp Birkenau far more emotional. It is very large, and will take you some time to walk around.
