    Passe exterieure Boulari, for us, is all about the thrill of the incoming current. It's not a gentle drift; we’re talking about a proper push that kicks off a fantastic channel dive. Dropping in here, the feeling of that water moving is immediate, you’re part of something big. The maximum depth of 22m keeps it accessible, but the current gives it an edge. When the tide is right, this place transforms. We've seen grey reef sharks schooling here, a proper wall of them, just hanging in the flow. They're often joined by sizeable barracuda and impressive numbers of loaches, their bodies angled into the current. Keep an eye out for eagle rays gliding past, almost effortlessly, and we've even been lucky enough to spot mantas here, using the incoming water to feed. The coral itself is healthy, a mix of plate and branching formations, but the real show is the pelagic life that congregates. It’s a site for divers who appreciate dynamic conditions and the promise of big animal encounters, a proper rush that ends with a relaxed drift further into the pass.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
