On Sunday, 12th Feb I visited there with one of the guy living with us in PG at Marine Lines. My mobile battery was dead so most of the pics are taken from other sources. The Hanging Gardens, in Mumbai, also known as Pherozeshah Mehta Gardens, are terraced gardens perched at the top of Malabar Hill, on its western side, just opposite the Kamala Nehru Park.
You can reach here to get a taxi or auto from any corner of Mumbai via the Walkeshwar Road and Ridge Road. The nearest railway station is Grant Road, from where the garden is just 20 minutes walkable or you can get a taxi from the station to reach here.
