The bärenquell brauerei is a very huge site, so please check out the google maps location below and the picture. 

If you are travelling towards the location along schnellerstr (on map as Bundesstrasse) from Schoneweide s-bahn, turn right down the side of the brewery heading towards the spree river and you will find an entrance there on the left hand side.

We will put up some arrows on the posters pointing in the right direction.
