The Sardine Run is a phenomenon where large numbers of sardines swim about in groups big enough to block out the light from the sun. They make their way from the deep into the shallows to feed on planktons. It is not unique to the Philippines and is also an event which can be witnessed in South Africa. Although the South African Sardine Run holds the title of the greatest sardine run in the world, Cebu’s Sardine Run can still hold a candle as the second best.
