Hin Ta Hin Yai, also known as Grandfather and Grandmother Rocks, are curious granite formations located on the southern shore of Ko Samui. These rocks have been sculpted over millennia by wind and waves, resulting in shapes that bear a striking resemblance to human genitalia. Hin Ta, the Grandfather Rock, is slender and erect, appearing phallic, while Hin Yai, the Grandmother Rock, is more rounded and cleft, resembling a vulva.
