SD Point - Lombok & Gili Islands

The Crack at Pulau Babi isn’t just a wall; it’s a living labyrinth, especially when you start exploring its namesake. We love dropping in here, letting the gentle current (it’s rarely a serious push) carry us along the face. Keep an eye out for those Blue-finned Rock Cod tucked into the crevices; they’re masters of camouflage. The wall itself is thick with whip corals and sea fans, but it's the smaller stuff that really shines. We’ve spent solid chunks of dives just poking around for Gardiner's Headshield Slugs and the tiny, grumpy-looking Blennies. Down deeper, around 18-20m, the wall develops these incredible fissures and overhangs, almost like the rock is peeling open. That's "The Crack." Slip inside and the light filters down in shafts, illuminating schools of Banded Blue Sprat that shimmer like a liquid curtain. It’s wonderfully atmospheric. We’ve seen reef sharks cruise by in the blue, though usually they're just passing through. This site is fantastic for macro photographers and anyone who enjoys a slow, detailed dive rather than a pelagic hunt. The maximum depth of 22m makes it accessible for most certifications.
