Writing on Twitter, Hilton said: Wow"! What an amazing night! @RiverViiperi and I made a grand entrance to our party tonight riding in on a huge elephant. Only in Goa! In Mumbai, just went to the toy store and bought lots of toys."
The 31-year-old visited the children at Ashray, a part of the Committed Communities Development Trust (CCDT), where she was greeted with a traditional 'aarti' and later joined the children to dance to the song 'Chammak Challo' from Ra.One.
Speaking at the event, she said: "I am so happy to be here and meet you all. It is holiday time and Christmas is coming. I hope you like the presents.
"I admire the work done here. It makes me so happy."
The heiress, who visited India last year to launch her range of handbags and accessories, has revealed that she has been offered a number of Hindi cinema roles.
She is also expected to visit Mumbai's famous Siddhivinayak temple.
Hilton made her debut as a DJ this summer during a music festival in Brazil.
