    Nanjalakalau Wall is our pick for a really solid drift dive in Iron Bottom Sound. We love how the wall just drops away into the blue, creating this perfect setup for cruising along and letting the current do the work. You’re always looking two ways here: into the wall’s crevices for Painted Spiny Lobsters and sneaky High Hat Triplefins, and then out into the open water. That’s where the bigger stuff hangs out – we’ve seen eagle rays glide past and Giant Trevally patrol the deeper edges. The gorgonian fans are truly prolific, a thick tapestry of them, and sometimes you spot a banana nudibranch inching its way along. Visibility isn’t always phenomenal, averaging about 11 metres, but on a good day, it opens up enough to really appreciate the scale. If you're comfortable with a bit of current and enjoy the feeling of flying along a reef, Nanjalakalau is a fantastic afternoon spent underwater. Keep an eye out for the Grey Reef and Black Tip Reef Sharks often spotted a bit deeper, below 20 metres.

    Safety Notes
