    White Rock sits between Mae Haad and Koh Nang Yuan, an easy run from most boats. It's a great spot for a relaxed dive, especially if you’re still getting comfortable in the water, with a max depth around 20 metres. We love dropping in on the north side, letting the current, if there is one, drift us gently south. You’ll find two main boulders here, close enough to swim between, acting as home base for a good spread of reef fish. Look for the Goldspeckled Shrimpgoby, always a favourite, tending its burrow. The real draw here is the sheer number of fish – schools of Blue and Gold Fusiliers often hang in the blue, sometimes so dense they dim the light. Paddling through them feels like swimming through liquid silver. The Staghorn coral patches are coming back nicely, too, offering shelter for Rivulated Parrotfish and tiny Western Gregorys. Yes, Trevor the Triggerfish is still around, patrolling his patch. He's got a reputation for a reason, so keep an eye out, but honestly, we've had more intense encounters elsewhere. It’s a pretty site, especially in the late afternoon light, a good one for practicing buoyancy and just enjoying the swim.
