I hope it's some way into the sea and they develop it into a celebration of Maratha history with a complete package where families can take a boat ride (maybe a decent loop), good food, plays, light n sound shows, story telling, cultural crafts and activities, a day in the life and times of Cchatrapati Shivaji Maharaj. Make it like a gadh (fortress) at sea. Maybe an invading naval force being repulsed. Love the Vijaydurg fort.
That would be a bad idea for the health of the family.
The water in and around Mumbai and across beaches in the city is a cesspool of faecal matter. The faecal coliform (FC) ( bacterium found in human and animal excreta) is between 100 and 1,000 times higher than a permissible limit.
Its best to keep away children from the beaches and waters around Mumbai.
It is better not to speak about the smell. Every passing year it seems to get worse. It will be a holiday from hell.
