    StandoutExceptional marine biodiversity

    Shimozone is often our go-to when conditions align for a proper drift. This deep pinnacle in the Keramas usually brings in some bigger pelagics, like dogtooth tuna and schooling barracuda, when the current is running. It's an expert-level dive, no question, best suited for those comfortable with strong flow and negative entries. We wouldn't recommend it for newer divers; save this one until you've got a few hundred deep, current dives under your belt.
