    Usaha Dua isn't your typical Singapore dive. Forget the usual reef dives here, this is a legitimate wreck, and it’s one we find ourselves drawn back to. Dropping down, the first thing you notice is the silhouette of the merchant vessel, pretty broken up now, but still very much a wreck at 11 metres. We love how it’s become an apartment block for creatures you wouldn't expect in Singapore's harbour waters. Look for the resident moray eels peeking out from rusted plates and the occasional stonefish perfectly camouflaged on the decking. It's a great spot for macro enthusiasts too, with nudibranchs often spotted on the encrusted metalwork. Our favourite time to dive Usaha Dua is on a calm morning, just after high tide, when the visibility gets a fighting chance. It’s a site that rewards patience and a keen eye, proving there's more to Singapore diving than meets the surface.
