    StandoutExceptional marine biodiversity

    Irian Sarmi is one of our favourites in the Southern Islands, a proper old wreck that always gives you something new to look at. We love the way the light filters down through the murky green, illuminating different sections of the hull as you circle it. The ship, a 62-meter motor vessel that went down in '68 after taking on water, sits upright at 15 metres, so it’s a good easy dive for anyone comfortable with Singapore’s often lower visibility. You’ll spend most of your time exploring the deck and superstructure, which is now completely encrusted. Look closely and you’ll find nudibranchs, often some vibrant colourful ones, and we’ve seen plenty of large groupers sheltering in the deeper holds. Keep an eye out for resident batfish, they’re usually swirling around the masts. The currents here can pick up, so we’d suggest timing your dive for slack tide if you want a more relaxed exploration. It’s a surprisingly intact wreck for its age and location, offering a real sense of history beneath the waves.
