Visiting a formation of rocks may not be something you had at the top of your to-do list, but these incredible structures are unique and definitely worth a trip whilst exploring Koh Samui!

Grandma and Grandpa Rocks

This collection of rocks is located at the southern end of Lamai Beach, only a 10-minute drive from Chaweng. We stopped for a swim first and parked our motorbike at the opposite end of the beach, but it was quite a walk to reach the rocks so we would recommend driving to the attraction and paying a small fee of 20 baht for parking.

More formally known as Hinta and Hinyai, the oddly shaped rocks strangely resemble male and female genitalia, with ‘Penis Rock’ being the star of the show.

At the entrance, there is a small shopping village along with a number of food and drink stalls to enjoy before you head down towards the rocks. Visiting doesn’t take that long at all, as there isn’t much to do other than giggle, take a few inappropriate photos and smirk as you pass other tourists. Still a very unique sight to see nevertheless!

Overlap Stone

Whilst researching things to do in Koh Samui, we were struck by this incredible rock structure which finely balances high above the landscape. If you’re up for an adventure, the stone is well worth seeking out as the views at the top do not disappoint!

Getting to the Overlap Stone is quite difficult as it is located up steep hills into the jungle. Google Maps had to come to the rescue for us, although we still managed to drive past the turning! If you are visiting by motorbike, the road to the top is really steep with plenty of sharp corners, so take it steady as you ride up. 

As you climb higher and higher, there is a small house on the right with signs for parking. We parked our bike here for 20 baht and followed more signs towards a viewpoint, which we thought was the Overlap Stone at the time. Instead, we stumbled across a hidden gem which overlooks Lamai Beach and the beautiful surrounding landscape.

From here, the Overlap Stone is a five minute walk up a steep path but there are signs to point you in the right direction. At the end of the path is a small house and the stone is situated opposite and across a small bridge. You definitely wont miss it though – its huge!

Access to the stone is free, but there is a tip box to leave 20 baht on your way out which probably goes to the lovely woman who lets people walk across her garden everyday.

The views from the top are truly amazing and the huge rock structure balancing on the edge is a little overwhelming! The roped walkway is also a great place to capture some photographs, so make sure you don’t miss out!

Lamai Viewpoint and Valentine Stone

If you have a few hours to spare, we also recommend visiting Valentine Stone which has signs directing you from the main road not far away from the Overlap Stone. 

The fee to enter is 200 baht and although the rock isn’t that impressive, a short cable car ride to the top of the attraction has amazing views! 

The top is actually named Lamai Viewpoint and has similar scenery to the Overlap Stone, but here you can enjoy a cold beer from the bar and soak in more of the incredible landscape. The viewpoint also offers a zip-line adventure at an additional price for those who are braver than we are!
