Dharavi is a working district of roughly a million people, with a recycling trade, potteries, tanneries and bakeries turning over hundreds of millions of dollars a year. The walks here are led by residents and by organisations that return part of the fee to the neighbourhood, and photographing people or homes is generally not permitted. Below are the 15 guided walks available, who runs each one, how large the groups are, where the money goes, and what each costs.
