Beneath the clear waves, one of the most rewarding things to do in Maldives is swimming with its impressive marine life. From hundreds of manta rays to colossal whale sharks, the warm waters of the region make the atolls a magnet for a variety of creatures. Its currents and lagoons provide nutrient-rich habitats for life underwater to thrive, creating a variety of ecosystems for visitors to explore. Head to Hanifaru Bay, a UNESCO-Protected Biosphere, and encounter otherworldly congregations of manta rays, flocking around feeding stations by the hundreds. Further south in the South Ari Atoll, glide through the deep blue with the world's largest fish, the ever-abundant whale sharks.
