Why dive here
With 182+ marine species recorded in the area - including barracuda, lionfish, mandarin fish, napoleon wrasse and nautiluses - Chuyo Maru offers some of Rock Islands's richest wreck diving. Water ranges 29-30°C, warmest June, October, November.
The *Chuyo Maru* in Palau's Rock Islands isn't just a sunken ship; it’s a time capsule. We love how the story of this WWII supply ship unfolds as you descend, the sheer scale of it emerging from the blue. It sits upright and relatively intact, a genuine wreck dive for those who appreciate history and exploration. Dropping down, the ship’s mast points towards the surface, encrusted with a rough tapestry of coral and sponges. Inside the cargo holds, we often find shafts of light cutting through, illuminating schools of fusiliers so thick they practically block the view. Look closely for the smaller residents – Nagasaki damsels flitting between the rusted beams and cryptic gobies tucked into crevices. Out on the deck, large lionfish often pose, unbothered by divers, and we’ve spotted sizable mottled conger morays peering from pipes. This wreck rewards a slow, observant dive, giving you time to appreciate the blend of human history and natural reclamation. It’s definitely our pick for divers who want more than just a quick look.
