Oral accounts say it was named by the Chinese pirate leader, Limahong, when he made it his sanctuary after being chases by Juan Salcedo, the conqueror of Ilocos provinces. He mended his ships in some of the islands while he and his men dropped anchor and landed ashore where they saw natives gathering clams, locally known as 'lucan'.
A Chinese approached and asked a native what the clams were called. The native answered “Lucan nga ucap” and that it is good to eat. The Chinese pirate told his companions that the thing was “lucap.” From then on, the place was called Lucap, which is now the jump-off point to the Hundred Islands.
