About this spot
Koh Island sits in Raja Ampat Regency, Southwest Papua Province, one of Indonesia's premier dive destinations. The island draws divers seeking diverse marine encounters in waters known for rich biodiversity. Year-round diving means you can plan a trip to fit your schedule, though conditions vary seasonally across the region. The island's marine environment supports 12 recorded species, reflecting the broader Raja Ampat ecosystem's reputation for abundance. Coral bleaching warrants monitoring, so check current conditions before booking. Community divers have documented three videos from the site, offering real-world insight into what to expect below the surface. Koh Island is not within a Marine Protected Area, which shapes access and regulations. The lack of MPA designation doesn't diminish the diving experience but means fewer restrictions on boat traffic and entry. Nearby islands and reefs often offer complementary dives within a multi-day itinerary. Before diving, gather local intel on current visibility, depth ranges, and site-specific hazards. Raja Ampat operators vary in experience and equipment standards, so verify boat safety and guide credentials. Bring your certification card and discuss your skill level with your chosen operator.
