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 - Yulliet Besar offers some of Raja Ampat's richest diving. Water ranges 29-30°C, warmest May, November, December.
Yulliet Besar, just north of Pulau Yulliet, is a pretty consistent performer, especially for a night dive. You’ll find plateaus from 5-10 meters, then slopes and walls that dip to around 20 meters, though our computers often read closer to 21 meters max. Visibility averages 15 meters, which is decent enough to spot the hogfish and some of those tiny Marshall dottybacks. We’ve had good luck with pygmy gobies here, the forktail and Stobbs' varieties are often tucked into the staghorn coral. It’s a comfortable dive, nothing too taxing, and a nice spot for macro hunters looking for a relaxed pace.
Safety Notes
Strong currents typical this month (avg 35 cm/s). Good buoyancy control essential.
