Grandfather & Grandmother Rocks are a couple of oddly shaped rock formations on Koh Samui. Here’s all you need to know about visiting.
How To Get To Grandfather & Grandmother Rocks
Grandfather & Grandmother Rocks rocks are located at one end of Lamai Beach.
Easily accessible by road it’s better to take the main highway and park at the correct entrance, than clamber over the rocks at the end of Lamai.
We stayed in the Chaweng area of Koh Samui and rented a scooter for 150 Baht per day. This gave us access to the whole island!
It took us around 25 minutes to drive down from Chaweng to Lamai and whilst in the area we recommend checking out Lamai Beach and Overlap Stone Viewpoint.
If you’re looking for transport to and from Koh Samui, you can pre-book all of your Lomprayah transfers.
For those short on time, or that prefer everything to be organised for them, there are some awesome tours on Get Your Guide available to book in advance.

Best Time To Visit Grandfather & Grandmother Rocks
For the best weather in Koh Samui, December to August is the dry season when the weather is sunny and hot.
The wet season runs from September to November, when there is heavy rainfall,, and high humidity.
Grandfather & Grandmother Rocks are a very popular tourist attraction, so it an get pretty busy here, especially during peak tourist season.
If you want to avoid the crowds, like most attractions, get there early or late in the day, before or after the bus trips.
The rocks can be a bit slippery so good footwear is recommended.
This is a great place for some fun photos!
What To Pack
What To Expect At Grandfather & Grandmother Rocks
We kept seeing it pop up, excuse the pun, on various things to do in Koh Samui blogs. So we had to take a drive down to Lamai Beach to see what all the fuss was about.
And to be honest, this unusual tourist attraction was pretty impressive!
The rock certainly resembled a penis and stood alone amongst all the smaller and less significant rocks.
There were tour buses piling in by the dozen, with tons of people lining up to get there photo taken with the resemblance of male and female genitalia.
So, if you fancy including Grandfather & Grandmother Rocks into a day tour, you should check out the 7-Hour 4WD Wild Jungle Safari Tour Including Lunch.
The Thai name for the natural sculptures is: Hin Ta & Hin Yai Rocks.
‘Ta’ meaning Grandpa and ‘Yai’ meaning Grandmother.
We assume this is the locals way of softening the blow and taking away any kind of crudeness that they could from what can only be described as a giant penis and a giant vagina waving to the ocean.
We floated around and watched on as elderly Chinese men and mothers with young daughters giggled their way around the viewpoint.
Aside from the rock formations, the views out to the ocean were pretty incredible. There were even a couple of rock pools to relax in.
Overall Grandfather & Grandmother Rocks are well worth a visit if you have time to spare on Samui and fancy a giggle.
