Take the Berlin S-Bahn S1 (leaving every 20 minutes) to Oranienburg train station. Directly outside the main station entrance are the bus stops. You can catch the #804 bus to the camp but its only an hourly service that leaves at about 20 past the hour. The walk to the camp takes about 20 minutes. From outside the front of the station turn right and walk about 300m along Stralsunder Str. Turn right and go under the railway bridge. Keep walking until you reach a cross road, there is a Netto Supermarket on the corner, turn left along Strasse der Einhelt. Walk on the right hand side of the road until you reach a small memorial to the death march. Immediately turn right and keep walking you will eventually reach the camp and the visitor’s centre. Beware if you take Dianastrasse which is slightly shorter way to get to the camp as there is a gate controlled by a code. It was 2207 & the bell sign at the time of writing (still the same July 2012) or if there is a tour group in front the guide will know the code.
Oranienburg can be reached very easily from Berlin via the main north/south train line. Take the train to the stop 'Oranienburg' and from the main railway station the museum is a 20-30 minute walk and well signposted.

If you are on your own I would recomend buying a map for 50 euro cent...it is number and has details of each stop along the camp site....in addition you can rent for 5 Euros headphone in your language that coorisponds to each stop....(If you only have a short time I would recomend this)
I have only gone to Oranienburg to go to Sachsenhausen concentration camp but it seems a nice village anyway. Larger than most I have gone to around Berlin with a good central train station and what looked to be (as we rode the bus) a lot of nice restaurants and places around. Its a suburb of Berlin so many people take a train into the city to work then ride back out to live at the end of the day.
You must take the 804 bus to go to Sachsenhausen. Inside the station you can ask at the office at what time it comes around. When you are on the bus you have to make sure you tell the bus driver than you need to stop at the memorial of the concentration camp or he will not stop otherwise on his regular route. To leave the camp at around 17 minutes past every hour the bus comes to take you back to the station. Stand outside at the stop just past the gates to get a ride. I know its looks really deserted at night and everything, and you begin to fear it never comes along such a quiet regular looking street, but its comes.
You can take an Sbahn train with the direction of Oranienburg from Fredrichstrasse station. We happened to buy ours at Alexanderplatz and chose to take the longer routh along the outside of the of C section to see the countryside. But you can still get a ticket for a reasonable price around 6Euros.
