About this spot
Harto's Reef lies near Koruwoi Munde Island in the Raja Ampat Regency of Southwest Papua, one of the world's most biodiverse marine regions. The site draws divers year-round with healthy coral formations and consistent marine life encounters. Local community videos and species observations confirm the reef's productivity across multiple visit windows. The reef supports a diverse ecosystem documented through 12 species observations. Marine life encounters are frequent enough that the spot attracts repeat visits and video documentation from visiting divers. The coral structures remain active and worth monitoring, though bleaching watch status warrants attention to seasonal conditions. Harto's Reef sits outside protected marine area boundaries, meaning access is straightforward for independent divers and charter operators working in the region. The site's year-round viability makes it a flexible choice for Raja Ampat itineraries. Community contributions—both video and species logs—provide real-world intel from recent visitors.
