Come here for dozens of the largest mantas you’ll ever see. The smooth-gliding monsters, reaching six meters across, regularly come here to visit what is affectionately known as a "cleaning station." Smaller fish attach themselves to the mantas’ bodies to feed on parasites on their fins and wings before the rays cruise off squeaky clean. There are plenty of tropical fish to see too, including colored frogfish, deadly dragon moray eels with their distinctive read and white bodies, plus, if you’re lucky, bowmouth guitar fish and families of whale sharks.
