About Silica Reef (Tangdol Reef)
Silica Reef is a shallow coral reef off Puerto Princesa with a coral-capped top, a gentle slope, and enough structure to make it a calm, photo-friendly boat dive. The route rewards slow swimming and careful buoyancy with soft corals, small reef fish, lobsters, giant clams, and the kind of easy conditions that suit relaxed exploration rather than a rushed current chase.
