Taking up a whopping 100 hectares or so of land, the Rostov Zoo is one of the biggest zoos in Russia. It has remained a prime source of entertainment for generations of Rostov townsfolk. You can spend all day here, and you won’t regret it. The Rostov Zoo boasts a highly representative wildlife collection. Centre-stage belongs to Comet the polar bear, Ustin the Amur tiger, Amur the Far Eastern leopard (there are only about 80 of them left in the world), and Sitara the elephant. Birds of prey, apes, monkeys and ungulates are available in profusion. A family of porcupines have recently joined the old-timers of the Rostov Zoo. They have an outdoor cage all to themselves.
