Cobrador Sunken Island
Why dive here
With 176+ marine species recorded in the area - including giant moray eels, sea turtles, sperm whales, lionfish and pufferfish - Cobrador Sunken Island offers some of Apo Reef's richest wreck diving. Water ranges 28-30°C, warmest May, June, July.
Cobrador Sunken Island isn't really an island at all, more a submerged plateau with a fascinating secret. This isn't your typical wreck dive with a clearly defined ship. Instead, we’re talking about a former lighthouse station, a concrete structure that toppled into the depths during a typhoon decades ago. It's a jumble of concrete blocks, twisted rebar, and scattered debris now heavily encrusted and completely reclaimed by the sea. You'll find yourself navigating through swim-throughs formed by fallen slabs, peering into shadowy crevices where nurse sharks often snooze. Schools of bigeye trevally swirl around the structure’s perimeter, their silver scales catching the light. We love exploring the nooks and crannies here, especially looking for the moray eels that seem to have taken up residence in every available pipe and crack. It's a great spot for macro too, so bring your keen eye for nudibranchs and flatworms camouflaged against the encrusting corals. The visibility is usually excellent, allowing you to appreciate the sheer scale of the collapse and the new ecosystem it has fostered.
