Okikawa Maru - Apo Reef
The Okikawa Maru is a beast of a wreck, sitting upright in about 26 to 34 metres, and it’s our pick for anyone who loves a bit of history with their nitrogen. We love how vast it is; you can spend a whole dive just exploring one section. Its sheer size means there are plenty of penetration points, though we’d suggest leaving those for advanced wreck divers who've got proper training and lights. What makes it special is the way the reef has just swallowed it whole. Every surface is carpeted in corals, and you’ll find resident white-tip reef sharks often cruising through the cargo holds. Look closely in the darker corners and you might spot a big marbled stingray. We’ve seen schools of snapper so thick you can barely see the bow from the stern, and the anenomefish here are particularly bold. On the dive back up, keep an eye out for turtles munching on the corals growing from the deck. It’s a dive that rewards slow exploration, especially when the current isn’t ripping through.
