About this spot
Mangrove and Slope sits near Yanggelo Island in the Raja Ampat Regency of Southwest Papua Province. The site combines shallow mangrove habitat with deeper slope diving, creating two distinct ecosystems in one location. Mangroves provide shelter for juvenile fish and invertebrates, while the slope descends into deeper water where larger pelagics and reef dwellers thrive. Raja Ampat is one of the world's most biodiverse marine regions, and this spot delivers on that promise with documented sightings of 12 distinct species. The area remains outside protected marine areas but sits within a region known for robust coral health, though monitoring for bleaching stress is recommended. Year-round access means you can plan your trip based on your schedule rather than seasonal windows. The site has generated community video content, indicating it draws regular diver traffic and interest. Whether you're interested in macro work in the shallows or larger reef formations on the slope, Mangrove and Slope provides variety in a single dive.
