Grandfather and Grandmother Rocks or in Thai "Hin Ta Hin Yai" is located at the south end of Lamai Bay which is always a part of all Koh Samui day tours. This is also one of the most popular places for sightseeing attractions among the Thais in Koh Samui. I also visited this place on my first trip to the island myself.
Hin Ta (grandfather rock) is granite in a unique shape that looks like a male sexual organ caused by erosion by sea, wind, and sun, while Hin Yai (grandmother rock), in the same area, looks like a female sexual organ.
There are stalls for food and souvenirs all along the path leading down to the rocks. Here, do not miss an opportunity to try "Kalamea" (the Thai equivalent of French caramel). This sweet is made from glutinous rice flour, palm sugar, and coconut cream. It’s soft and mildly sweet. This delicious Thai dessert is a specialty of southern Thailand, more specifically Koh Samui, thanks to the many coconut tree plantations here. This is one of the items Thai visitors always buy as souvenirs from Koh Samui for their friends and family. Try out Kalamea with your coffee in the morning, I’d say it goes really well together. (Just by writing about Kalamea, it already makes me hungry)
