    StandoutExceptional marine biodiversity

    Elephant Head, or Hin Pusa as it’s known locally, is one of those Similan sites we always look forward to. It’s a granite boulder labyrinth, not a coral reef, and that’s precisely why we love it. You drop into this maze of swim-throughs and tunnels, feeling the slight surge pull you through narrow passages. Sunlight shafts pierce the openings, illuminating schools of blue and gold fusiliers that swirl so thick they momentarily block your view. Our favourite part is navigating the deeper sections, where you’re often rewarded with a glimpse of blotcheye soldierfish tucked into crevices. Keep an eye out for scribbled angelfish cruising the rock faces and poss' scorpionfish perfectly camouflaged on the granite. The sheer scale of these boulders, some the size of small houses, is impressive. Current here can be a bit frisky, especially around the outer pinnacles, so it’s best for divers comfortable with a drift. We’d suggest going early in the morning before other boats arrive; it gives you the space to truly appreciate the quiet grandeur of the place.
