Arefi Reef
Protected Area
Selat Dampier (Raja Ampat)
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 - Arefi Reef offers some of Raja Ampat's richest reef diving. Water ranges 29-30°C, warmest May, November, December.
We often hit Arefi Reef as the second stop on a Batanta trip, a good hour from our base. It's a shallow spot, topping out around 21 metres, and tends to be a relaxed drift. Visibility averages around 17 metres here, so things are clear enough to spot the resident Freycinet’s epaulette sharks tucked under ledges. You'll likely see a few ghost cardinalfish darting about too, along with halfmoon triggerfish cruising past. It’s a solid, easy dive, perfect for warming up or winding down after the P-47 wreck.
