Why dive here
With 82+ marine species recorded in the area - including manta rays, mobula rays (devil rays), whale sharks and pufferfish - Duka Bay Pier offers some of Siargao's richest reef diving. Water ranges 27-30°C, warmest June, August, September.
Duka Bay Pier offers a relaxed dive under the structure, attracting a good mix of smaller reef fish and critters. We’ve spotted frogfish, nudibranchs, and schools of juvenile barracuda often hang out in the pilings. It's a straightforward shore entry, perfect for a leisurely afternoon dive or for divers looking to practice their macro photography skills without strong currents.
