Good for half a day family event. Book some time for all the walking, there are many mileages or kilometers to walk but during nice weather , it is a well spent day for the family and children. If you have visited many big Zoo's in the world, your expectations might be higher than what Tallinn Zoo can offer. At the same time, there are elephants, tigers, snakes, apes, bears, etc etc- just take a small trolley for an extra fee at the entrance. Some food can be purchased on sight but nothing to be very entusiastic about, more like damage control when kids get hungry and angry, it is in the middle of the Zoo after the elephants and before the tigers.
