    Kat's Kables always feels like a bit of a treasure hunt, and that's why we love it. The real draw here isn't just the resident parrotfish or the occasional sleepy whitetip reef shark tucked under a ledge, it’s the sense of history. You're swimming over these old communication cables, relics from when Direction Island was the internet hub of the Indian Ocean. It’s a strange juxtaposition, seeing the vibrant corals growing right alongside this chunky, industrial-looking cable disappearing into the blue. We usually drop in and follow the cable, keeping an eye out for mantas cruising by in the deeper water. The coral growth here, particularly the Cauliflower and Montipora, is really something. Look closely among the coral bommies for the smaller stuff, like the adorable Reef Margin Blenny or a well-camouflaged Coral Hawkfish. Visibility often pushes past 25 metres, giving everything a lovely, clear definition. This site is perfect for those who appreciate a bit of unique history with their reef dive, offering a gentle drift over a healthy reef with an interesting twist.

    Safety Notes

    Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
