Blue Hole Tablas
Why dive here
With 176+ marine species recorded in the area - including giant moray eels, sea turtles, sperm whales, lionfish and pufferfish - Blue Hole Tablas offers some of Apo Reef's richest cave diving. Water ranges 28-30°C, warmest May, June, July.
Dropping into Apo Reef's Blue Hole is a proper descent, straight down into the deep blue. We're talking a massive sinkhole here, with plenty of reef sharks often circling the rim as you make your way in. It’s a dive for those comfortable with overhead environments and deeper profiles, offering a unique geological feature rather than a coral garden. The real draw is the sheer scale of the hole itself.
Safety Notes
Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
