At the end of Lamai Beach, on a small cape, you will find the two rock formations that are known as Grandmother Stone and Grandfather Stone (Hin Ta and Hin Yai) - two rocks that are on Koh Samui revered as fertility symbols. The place is very popular among tourists and the short path that leads from the highway to the shore is lined with many, many stalls that offer cheap clothes, costume jewellery, and all kinds of souvenirs. Not far away from here is the Overlap Stone, an excellent viewpoint, but difficult to reach. The trail is very steep and you can drive only about half the way up and have to hike the last kilometre (bring a bottle of water and a lot of energy!). Once you are on the top, however, you are rewarded with beautiful views of the southern coast of Koh Samui. You can find the trail if you drive on the highway past Hin Ta and Hin Yai and watch out for a sign on the right side of the road that says 'Overlap Stone'.
