The Indian scenes were actually shot in the hilly city of Kandy in central Sri Lanka because the filmmakers were denied permission to film in North India. Kandy was the last capital of the Sri Lankan kings and is a UNESCO world heritage site partly due to the Temple of the Sacred Tooth Relic. Kandy is also home to Pinnawala Elephant Orphanage, in which the elephant scenes were shot.
Kandy played a central role in the tea plantation industry once tea production took off in Ceylon (Sri Lanka was previously known) in the latter part of the 19th century. The Mayapur village is part of the sprawling Hantane estate near the city. It's home to some of Sri Lanka's greatest tea plantations.
