Zoo in tallinn used to be the top attraction for all the kids from outside the city, and also for the locals. I came from Tartu, so a visit to the zoo was always really on top of the entertainment list when coming to Tallinn. Funny, but it still is. Once a year I always go. The area is quite big, kind of like a forest-park situated out of the centre of town and by the sea. It takes around 2-3 hours to walk through it all.
One of the symbols of the zoo, the polarbear Franz sadly overdosed a couple of years ago. On what, you ask? Tranquilizer, sadly. He managed to escape, but did not get too far. Despite that sad story there are 7,200 other creatures, out of those 1,057 are mammals. Some quite rare species are living here too: snow leopards, who’ve just had cubs, a Chinese alligator, Amur tiger and a black rhinoceros.
I would really suggest it if you have kids in need of draining some energy for the evening, if you are planning to go out. Also, there is a large shopping centre opposite the zoo, with some restaurants and lots of shops for cooling down from the emotions later. It is called Rocca Al Mare.
The zoo is quieter in winter but some animals are seen more often in winter, like the snow leopard with cubs.
