The Giant Clam Sanctuary, situated in Sitio Kibila, Barangay Cantaan in Guinsiliban, Camiguin, plays a vital role in the conservation of giant clams, an endangered species. This sanctuary not only allows visitors to snorkel in a specially designed man-made pool, providing a unique opportunity to learn about these remarkable clams, but it also functions as a pearl harvesting nursery. As an integral part of the Guinsiliban Aquamarine Park, the sanctuary promotes eco-tourism and environmental awareness, encouraging visitors to appreciate and protect our marine ecosystems.
