What’s so special about Mumbai?” Raju asks his elder brother Raghu Dada. “Everything! ... It is jhakaas,” he replies.

Raju was led to the question because on his first day in class 4, his teacher Miss Pinto asked if any student had visited the Elephanta Caves. None had. And when she asked if anyone had been to Horniman Gardens, she received the same answer. So, Miss Pinto’s next project for the class was to get them to visit as many places in the city as possible. Fortunately for Raju, Raghu Dada was a tour guide who not only knew Dharavi, where they lived, but the city as a whole. And thus begins the adventure in Off We Go! To Mumbai, To Mumbai, part of a series released this month, created by the Indian National Trust for Art and Cultural Heritage (INTACH) and Speaking Tiger. Versions for Delhi and Kolkata are available, too.
