Why dive here
With 496+ marine species recorded in the area - including barracuda, blacktip reef sharks, blue-spotted stingrays, bull sharks and octopuses - Sumilon Sanctuary offers some of Dumaguete's richest reef diving. Water ranges 28-30°C, warmest June, July, October.
Sumilon Sanctuary is a solid choice when you're looking for an easy dive out of Dumaguete. The reef tops out around 5m and slopes gently down to 22m, making it ideal for beginners or those wanting a relaxed swim-through. You'll find plenty of resident anthias flitting around the hard coral patches, and we often spot whitetip reef sharks resting under ledges in the sand channels. Keep an eye out for blue-spotted rays gliding across the bottom. It's a protected area, so the fish are quite comfortable with divers, offering some good photo opportunities.
