Banganga Tank is one of the oldest sweet water tanks located in Mumbai. Before Mumbai got water supply from the Vihar and Tulsi lakes, the only source of water were several tanks built within the city. There were eleven tanks in all, of which Banganga is the only tank that has been present since ancient times. It is a great destination for a weekend cycle ride. The distance from Andheri to Banganga is just over 25 km one way.
