Grandmother and Grandfather Rocks - or Hin Yai/Hin Ta - are rocky outcrops on Lamai Beach. Often photographed and commented on, the rocks bear an uncanny resemblance to male and female genitalia.
The rocks are set on a lovely stretch of beach, and create tranquil rock pools when the tide is in.
Grandmother and Grandfather Rocks - or Hin Yai/Hin Ta - are a little south along the sands of Lamai Beach, on Koh Samui’s southern east coast.
