Why dive here
With 236+ marine species recorded in the area - including blacktip reef sharks, manta rays, mobula rays (devil rays), pygmy seahorses and sea turtles - The Cathedral offers some of Raja Ampat's richest cave diving. Water ranges 29-30°C, warmest May, November, December.
The Cathedral isn't your typical Raja Ampat wide-angle reef. It's an atmospheric cave dive, more about the play of light and shadow than big schools of fish. Inside, the space opens up, and we'll often spot Hayashi's cardinalfish tucked into crevices or a shy chocolate chip sea star clinging to the walls. Look closer and you might even find a Denise's pygmy seahorse on a gorgonian fan. It’s a good spot for divers who appreciate the quieter, more intimate side of Raja Ampat, preferring exploration over a flurry of activity.
Safety Notes
Overhead environment - never enter without proper cave/cavern training, redundant equipment, and a guideline.
