Brewers' walking tours by maryamy
This is especially good for the English speaking crowds. Much walking and much history goes on...You can walk from 4 to nine hours depending on when you start.n This is on every day.
They also do Potsdam tours every other day.
They have leaftlets in the tourist info office or you can go for 9 am Circus (opposite a hotel I forget) or 9.30 at the New Synagogue.
Otherwise the times are 12 and 12.30 at the same places.
