Mysore is famous for zoo. The zoo is located in heart of city. And since mysore is not that expanded its easy ton reach as the traffic is not that much during weekdays and in weekend s the traffic will be more as it is one of the pit spot for tourist going to Nagarhole, wynad, ooty.
Zoo has almost all animals and birds, and the most important to visit is tiger Leela, white tigers and peacock.
Zoo is very vast in area and not so easy to cover the entire zoo. So I recommend to see the directions and try to visit important animals before getting tired.
