What to expect at Hin Ta Hin Yai
Funnily enough, this natural attraction is a very famous thing to do on Koh Samui. There is a whole touristic scene around these rocks but no entrance fee, only a parking fee of 10 Baht.
Hin Ta Hin Yai is also known as Grandfather’s and Grandmother’s rocks where ‘Ta’ means Grandfather and ‘Yai’ means Grandmother. The interesting rock formations with incredible view over the ocean are worth to visit. Funnily enough, the most exciting people who take a lot of pictures and giggle the most are the Chinese! The reason for that is, the rock formations have a bizarre shape, it resembles the female and male genitalia.
If it’s one of the things you can’t miss while on Koh Samui, I would honestly say no. You’re not missing out on something spectacular if you haven’t been to this place. It’s a funny spot and the view is beautiful, there are even a few rock pools where you can relax in. But there are far more beautiful spots on Koh Samui. It’s just a cool place to tick of from your Koh Samui itinerary!
