Hin Ta & Hin Yai (Grandfather and Grandmother Rocks)
หินตาหินยาย
A pair of striking rock formations on the coast at the southern end of Lamai Beach. Their shapes resemble male and female genitalia, and they are among Koh Samui's best-known landmarks.
The Grandfather and Grandmother Rocks (Hin Ta Hin Yai) sit on a headland at the southern end of Lamai Beach. Over many years, the waves have eroded the granite into two oddly shaped boulders. Local legend holds that they are an elderly couple who died at sea. A short souvenir street sits at the entrance. Visitors can walk out onto the rocks by the sea to view them, but the surfaces are slippery, so take care. Entry is free or costs a small parking fee. Nearby snack stalls sell coconut ice cream. The site can be combined with Lamai Beach and Lamai Night Market, and a visit takes about 30–45 minutes.
