The folklore of Samui Island tells the story of an old couple by the name of Ta Kreng (grandpa Kreng) and Yai Riem (grandma Riem) who lived with their son
in the southern province of Nakhon Si Thammarat. Since their son had come of age, they felt that it was time he got married.
One day they decided to sail to the neighboring province of Prachuap Khiri Khan to ask for the hand of Ta Monglay's daughter.
During their sea journey, their boat was seized by a storm. The old man and his wife were unable to swim ashore.
They died at sea, turning into rocks as proof to the would be bride's parents of their true intentions. The rocks stand there to this day.
