Y Reef

# Y Reef Dive Site Description

Y Reef, located at Coquille Island in Waigeo Island within Indonesia’s renowned Raja Ampat Islands, offers an exceptional diving experience in the Halmahera Sea. This intermediate to advanced dive site features dramatic underwater topography with steep walls and vibrant coral formations that create a striking Y-shaped structure.

Divers typically explore depths ranging from 15 to 40 meters, encountering pristine hard and soft coral gardens teeming with tropical marine life. The reef hosts an impressive array of species including groupers, snappers, barracuda, fusiliers, and schooling pelagics that patrol the blue water.

The site’s strong currents attract larger marine life, making it ideal for experienced divers seeking encounters with reef sharks and occasionally larger pelagic species. Macro photography enthusiasts will appreciate the abundant nudibranchs, crustaceans, and small reef fish inhabiting the coral interstices.

Best suited for divers with solid buoyancy control and current-diving experience, Y Reef delivers the spectacular biodiversity Raja Ampat is famous for, combining challenging conditions with world-class underwater scenery.
