Two naturally sculpted rock formations on Lamai Beach have become Ko Samui’s most photographed curiosities, their unmistakable shapes earning them the local nicknames “Grandfather Rock” and “Grandmother Rock.” These weathered granite outcrops have been carved by millions of years of wind and sea into forms that spark giggles and knowing looks from visitors worldwide, making them an essential stop on any Samui island tour.
Walking along the golden sand of Lamai Beach, you’ll spot these remarkable formations jutting dramatically from the shoreline and rocky coast. The larger “Grandfather” formation stands proudly near the water’s edge, while “Grandmother” rock sits further inland among the coastal vegetation. Photography enthusiasts gather throughout the day to capture these natural sculptures against the backdrop of turquoise waters and swaying palm trees. The surrounding beach offers excellent swimming conditions, and you can explore the tide pools that form around the base of the rocks during low tide. Small vendor stalls nearby sell refreshing coconut water and local snacks, while the gentle sound of waves provides a constant soundtrack to your visit.
Despite their cheeky reputation, these geological wonders create a surprisingly serene atmosphere where families, couples, and solo travelers mingle with good-natured humor. The playful energy is infectious as visitors pose for photos and share laughs about nature’s artistic sense of humor. Children delight in climbing on the smaller surrounding rocks, while adults appreciate both the geological marvel and the lighthearted break from more serious sightseeing.
Early morning visits offer the best lighting for photography and fewer crowds, though the formations are accessible throughout the day. Reach Hin Ta Hin Yai by renting a scooter, taking a songthaew, or joining an island tour that includes Lamai Beach stops. Bring sun protection, water, and a camera with plenty of memory space. The rocks are easily combined with other Lamai attractions, making this free natural wonder a delightfully amusing addition to your Samui adventure.
