On our way to Jaipur, one of the cities you’ll visit when you book for the Golden Triangle, we dropped by the Monkey Temple (also called the Monkey Village/Valley) and met Kanhaiya Sharma. He is indeed an expert- having lived in the area since birth and being a monkey whisperer- you can trust he will give you and your kids the most memorable encounter with the monkeys. I do recommend him. You can contact him at 09929002445. Enjoy your travels!
