In a city with abundant skyscrapers and year-round heat, it’s no wonder that rooftops have become a popular place to hang out. It seems that every high rise in the city has turned its roof into a bar, restaurant, swimming pool, or all three. Hotel guests at the Fullerton Bay or Marina Bay Sands can do laps far above the hustle and bustle of the financial district below. If you aren't staying at either hotel, go up to the Fullerton Bay’s Lantern bar or the MBS SkyPark for a sunset cocktail. Other sky-high locations for a tipple include Level33 in Marina Bay Financial Centre, Kinki’s rooftop bar in Customs House, the Screening Room on Ann Siang Road, and—the highest of them all, on the 63rd floor of One Raffles Place—1-Altitude.
