The 162-year-old Veermata Jijabai Bhosle Botanical Garden & Zoological Museum also known as Byculla Zoo, launched a 'Crocodile Trail' with an underwater viewing deck, billed as the first of its kind in Asia, to view crocodiles and gharials, officials said here on Monday.

The 'Croc Trail' - presently with three crocodiles and two gharials on the prowl - opened on Sunday to chills and thrills among the first awestruck viewers to the Byculla Zoo, as it is popularly known.
