New Drop-Off - Rock Islands
New Drop-Off. Now, this is a site we’ve always enjoyed, even if it sometimes plays second fiddle to its more famous neighbours. You’re looking at a truly impressive wall here, dropping from a relatively shallow reef top down into the deep blue. We like to drift it slowly, letting the current carry us past the gorgonian fans that cling to the wall, feeling that gentle pull on our fins. Keep an eye out for the smaller stuff nestled in the cracks. We’ve spotted Denise's pygmy seahorses here a few times, tucked into their usual fan corals, and the Latticed Butterflyfish seem to love this section of reef. But it’s the pelagic action that really makes New Drop-Off sing when the conditions are right. We've seen schools of Blackspot Surgeonfish moving like a single organism, and you’ll often find Longface Emperors cruising by. If you hit it around slack high tide, the visibility can be truly spectacular, giving you clear views down into the abyss. It’s a great drift dive for anyone comfortable with a bit of current and a good way to see a different side of Palau’s famous walls.
