Built in the 1920s, Marine Drive runs along the shoreline of the Arabian Sea, from Nariman Point to the foot of Malabar Hill. It is Mumbai's most famous thoroughfare, and a favourite spot for watching the sunset. Lined on the landward side by a crescent of crumbling Art Deco buildings, it is lit up memorably at night, prompting travel agents to dub it 'the Queen's Necklace'. At the top end of Marine Drive is Chowpatty Beach, the only beach in the central part of Mumbai. Though not ideal for sunbathing or swimming, it is a popular (though hectic) place to spend an afternoon, surrounded by beach traders, entertainers and beggars. It is the best place to watch the annual Ganesh Chaturthi Festival (during August/September), when vast models of Lord Ganesha are immersed in the sea. Marine Drive is also an exciting vantage point on Diwali, when there are stunning fireworks in the bay and all over the city. The thoroughfare is best avoided on weekends, when it can get extremely crowded and rather dirty, but the atmosphere is festive and some people love to mingle on busy days. There are many restaurants and cafes lining the street and it is lovely to either walk or drive along the road at night.
