    StandoutExceptional marine biodiversity

    If you’re diving Singapore, the Ragamas Tunda II & Inter Asia I wrecks are a standout. We love this site because it’s a proper dive into Singapore’s working maritime history. Dropping down, you hit the wreck at around 30 metres, which means you need to be comfortable with your depth. It’s two barges, not some grand ocean liner, but that’s precisely their charm. They’ve settled upright, and the structures are still largely intact, creating these fantastic swim-throughs and overhangs. You’ll find a surprising amount of soft coral growing on the exposed metal, a real testament to how quickly marine life reclaims things. Look closely, and you’ll spot nudibranchs, often some surprisingly colourful ones, and we’ve seen bamboo sharks tucked away in the shadows. Our favourite part is exploring the holds – they’re dark, a bit silty, so good buoyancy is key, but the way the light filters in through gaps in the hull is incredible. It’s a dive for those who appreciate the quiet history of a wreck and the small, resilient creatures that now call it home, rather than big pelagics.
