Dive Site Overview

Just off Samal Island, this dive site distinguishes itself with a sprawling, sloping coral reef that unfolds gradually as divers descend. It cultivates a rich and diverse habitat, inviting exploration from recreational divers across various certification levels.

Traversing Aundanao, divers navigate through extensive coral gardens that define much of the underwater topography, encountering various species throughout their descent. The typical dive profile involves a gradual descent along the slope, allowing for ample time to observe the intricate details of the reef system.
