Hin Ta and Hin Yai Rocks Ko Samui

Hin Ta and Hin Yai Rocks are two geological formations on the island of Ko Samui in Thailand. The rocks are located near the southern tip of the island and are a popular tourist destination.

The rocks are unique in that they resemble male and female genitalia, respectively. This has led to many locals and tourists referring to them as “Grandpa Rock” and “Grandma Rock”.

Hin Ta and Hin Yai Rocks Ko Samui

Despite their name, Hin Ta and Hin Yai Rocks are actually two separate formations. Hin Ta is the taller of the two rocks, standing at about 12 meters tall. Hin Yai is shorter, at about 9 meters tall. Both rocks are made of limestone and have been weathered over time to their current shapes. It is believed that they were formed millions of years ago by erosion from wind and water.

Hin Ta Hin Yai is located in Hat Lamai, Tambon Maret. This natural phenomenon originates from the granite eroded by sea water and heat to form weird boulders. There is hearsay among the locals that a long time ago the grandparents, Ta Khreng and Yai Riam, natives of Nakhon Si Thammarat, travelled by sail boat to Prachuap Khiri Khan for proposing the marriage of their son to a daughter of Ta Monglai. Unfortunately, a strong storm sank their boat in Hat Lamai and the grandparents drowned. Their bodies were washed ashore and turned into the stones as seen nowadays.
