This dive site, Apo Island Marine Sanctuary, stands as a monumental success story in marine conservation within the Philippines. Established as one of the country's pioneering sanctuaries, it strictly limits diver numbers to just 15 at any given time, fostering an intimate underwater experience. As a designated 'no fishing zone', the sanctuary actively promotes and aids the remarkable regeneration of its fish stocks, making it a vibrant and thriving ecosystem.
Internationally acclaimed as the 'clown fish capital of the world', divers can expect to encounter an astonishing density and variety of clownfish species amidst their anemone homes. Beyond these charismatic small inhabitants, the thriving reef system supports an abundant array of diverse reef fish, healthy hard and soft corals, and frequently attracts sea turtles, making for a lively and colorful underwater spectacle.
The best time to visit Apo Island is typically during the dry season, from December to May, when conditions offer optimal visibility and calmer waters. Highlights include exploring the exceptionally healthy coral gardens, observing the famous clownfish interactions, and experiencing a truly preserved marine environment. Divers and freedivers of all levels will find this site rewarding; however, due to the diver limit, it is advisable to book trips in advance.
