Marine Drive is a 3-kilometre-long boulevard in South Mumbai in the city of Mumbai. It is a 'C'-shaped six-lane concrete road along the coast, which is a natural bay. The road links Nariman Point to Babulnath and Malabar Hill. Marine Drive is situated over reclaimed land facing west-south-west. The bay is part of the Arabian Sea.
Marine Drive is also known as the Queen's Necklace because if viewed at night from an elevated point anywhere along the drive, the street lights resemble a string of pearls,forming a necklace. It is also the world's largest viewing gallery and hence has been a host to a number of events that take place along the promenade.
