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 - Nudi Rock Raja Ampat offers some of Raja Ampat's richest cave diving. Water ranges 29-30°C, warmest May, November, December.
Nudi Rock, tucked between Ajoi and Nayak, is exactly what it sounds like – a big rock that’s excellent for finding the small stuff. It’s a shallow dive, maxing out around 24 meters, which makes for plenty of bottom time to scan for nudibranchs, flatworms, and even hairy shrimp nestled among the coral and rocks. We’ve spotted Fang’s Dwarfgoby and Queensland Eviota here, alongside the more common Cheekscale Dwarfgoby. Visibility averages 16 meters, which is plenty for macro work. It’s an easy run from Juara Jetty, just four minutes, making it a good choice for a relaxed afternoon.
Safety Notes
