Pinnacle@Duxton Skybridge

Singapore's most celebrated public-housing project hides a viewpoint few tourists know: a 50th-floor sky garden, 156 metres up, that links all seven slender towers of the Pinnacle@Duxton in one continuous loop. For the price of a coffee — tapped from an EZ-Link transit card — you get a breezy 360-degree walk above the city, with the CBD skyscrapers, the port, Sentosa and the green ridges all laid out below. Because it's a working residential block, only a limited number of passes are sold each day, and rooftop opening hours apply. It's an offbeat, local's-eye alternative to the pricier observation decks, right by the Tanjong Pagar and Chinatown food scenes.
