Marianne. Now this is a dive we always look forward to when we’re in the Inner Islands. It’s a proper drift dive, letting the current do the work over a mix of granite boulders and coral patches. We usually drop in and immediately get swept along, often finning past dozens of blacktip and whitetip reef sharks just cruising in the blue. The granite formations here create some really fun swim-throughs and narrow channels. We love pushing through them, feeling the water accelerate a little, and popping out to find a school of eagle rays gliding past. Seeing 20 or 30 eagle rays together is a common sight here, and it always gets us buzzing. Keep an eye out for the smaller stuff too – delicate blennies tucked into crevices and those cool bloodspot pipefish swaying in the current. If you're lucky, a scalloped hammerhead might cruise by in the deeper blue, though they're not an everyday sight. Maximum depth is around 18 metres, so it’s a comfortable dive for most, but that current means you need to be comfortable with a bit of a ride.
Safety Notes
Drift dive - carry a surface marker buoy (SMB) and stay with your group. Brief the current direction before entry.
