    StandoutExceptional marine biodiversity

    The HIJMS Nagato is one of those wrecks that just… demands respect. We love it for its sheer scale, a colossal battleship lying upside down in 51 metres of water. Dropping down, you start to make out the ghostly outline, the immense bulk slowly resolving from the gloom. It’s an intermediate dive, sure, but really, this is for divers who appreciate history and don't mind a bit of depth. Our favourite part is exploring the bridge structure, now completely inverted. It feels surreal, swimming through these upside-down compartments, imagining the chaos of Operation Crossroads. Visibility here is usually good, often 20 metres or more, which helps when you're navigating such a large structure. Keep an eye out for the resident grey reef sharks patrolling the deck guns and the schools of fusiliers that dart through the openings. The Nagato offers a profoundly humbling experience, a silent monument to a bygone era, now a thriving artificial reef.
