Why dive here

The Southeast Corner at Apo Reef, for us, is where things really get interesting. We’ve drifted this corner countless times and it always delivers a proper shot of big-fish energy. It’s not about intricate macro here, though you’ll always spot a Bugeye Dottyback tucked into a crevice if you look. This site is all about the pelagics that sweep in from the blue. We love settling in and watching the schools of Mimic Surgeonfish and Saddled Parrotfish cruise by, sometimes in such numbers they seem to stretch forever. Keep an eye on the deeper blue; we’ve seen Dorado flash past like silver torpedoes more than once. The sheer density of fish life here is what makes it a standout. You’ll find walls of Horned Bannerfish, their long fins swaying with the current, and just as many Small-eyed Squirrelfish darting into every overhang. It’s a site for those who appreciate the wider ocean story unfolding before them. We’d suggest hitting it early in the morning for the best light and less boat traffic. It can have a decent current, so be prepared for a drift.
