Thiruvananthapuram Zoo, one of the oldest in the country, was established as an adjunct to the Museum in 1859 by the erstwhile Maharaja of Travancore, Uthram Thirunal Marthanda Varma. Over the period of time justifications of establishing a zoo have changed from mere exhibition and amusement to research, education and ex-situ conservation. Spread over 36.02 acres of land and located in the temple city of Thiruvananthapuram, the zoo offers rare opportunity for the visitors to experience and enjoy unparalleled picturesque and panoramic sylvan surroundings besides vivid animal collections.
Zoo has two natural lakes where more than 60 species of free ranging birds including migratory birds can be seen throughout the year. More than 100 different species of both exotic and indigenous plant varieties inside the zoo provide an excellent ambience to the visitors.
