Papua Passage - Rarotonga
Sand Patch. Now, this one's a favourite when we just want to watch the show unfold without too much effort. It's a quick hop from shore, and the beauty here is in its simplicity. You drop down, usually holding onto a line at 12 or 18 metres, and then you just… wait. And watch. We've seen blacktip reef sharks here patrolling with an almost bored elegance, sometimes grey reefs too, cruising in from the deeper blue. The sandy bottom isn't barren; we’ve spotted ornate pitar venus shells half-buried, little flea cones moving along. The whole experience feels very natural, like you’re just a quiet observer in their living room. Visibility averages 16m, so you get a good view of the action without feeling overwhelmed by an endless expanse. It’s perfect for those lazy afternoon dives, or when you just want a reliable shark encounter without the adrenaline of a full-on drift.
