If you want to avoid the crowds and get a different glimpse of Jerusalem, there are some great opportunities in the Old City for the next two weeks. From the JPost:
After putting their heads together, the Jerusalem Development Authority, the municipal Tourism Authority, the Tourism Ministry and the municipal company Ariel came up with a brilliant move called Autumn Nights in the Old City. Successful beyond their wildest dreams, it consists of special (free) Monday and Thursday programs offered from the beginning of September until the end of October. Among the goodies are two light-hearted guided tours, evening performances of vastly diverse music programs and discounted museums kept open until evening.
The article has lots of details of the sites that are open and the costs. If you like to take photographs, I’d recommend the Ramparts Walk and the Tower of David.
