Its a nice zoo, plenty of space and beautiful scenery from Jerusalem mountains and good air even in summer. Zoo itself is wuite standard, we havent seen anything special, but the good thing is that even when its very popular like in the holidays, its not crowded inside thanks to the vast space of the zoo. The parking is a whole other story. 11:00-15:00 it gets so packed you cant move. Recommend to come early or come by public transportation.
