Most tourists dont know singapore has diving at pulau hantu. Good visibility on clear days, soft corals, and plenty of reef fish. Not world-class but surprisingly good for a major port city.

Book with local dive operators — They run trips including gear. Two drift dives around the reef, usually see angelfish, parrotfish, and occasionally reef sharks. Water temp is 28-29°c year-round.

Diving possible all year round with varying conditions. Take the boat ride from west coast ferry terminal.
