It's a fascinating spectacle, looking down on row upon row of open-air concrete wash pens, each fitted with its own flogging stone, while Mumbai's dhobis (around 200 dhobi families work together here) relentlessly pound the dirt from the city's garments in a timeless tradition. Known as the world's largest outdoor laundry, Dhobi Ghat is where Mumbai's traditional washerfolk -- or dhobis -- provide a wonderful service, collecting dirty laundry, washing it, and returning it neatly pressed, all for a very small fee.
