The Legend of Hin Ta Hin Yai: Lanna Love Through “Grandma & Grandpa” Rocks

The Story of Hin Ta Hin Yai: Koh Samui’s Most Romantic Rocks

Thailand is a country bursting with stories of passion, fate, and everlasting love. One of the most beloved legends hails from Koh Samui, a tale that has shaped not only local lore but the way travelers view the island’s most iconic natural monuments: the Hin Ta and Hin Yai rocks, known to many as the Grandfather and Grandmother Stones.

If you visit Lamai Beach in the south of Koh Samui, you’ll notice two strangely shaped rock formations perched on the shoreline, catching the attention and giggles of passersby. These are Hin Ta (Grandfather Rock) and Hin Yai (Grandmother Rock), two natural sculptures that, at a glance, seem unmistakably human. Their forms represent the male and female anatomy, but there is much more to these stones than first impressions suggest.

The Lanna Legend: True Love Set in Stone

The roots of the story draw not just from local Samui fishermen, but from the romantic folklore of the ancient Lanna kingdom, which encompasses much of northern Thailand. While Hin Ta and Hin Yai are most famous in Samui, the core sentiment echoes traditional Thai tales of family honor and sacrifice.

The Immortal Love Story

The legend goes like this: Once upon a time, an elderly couple from the Lanna region, Ta Kreng (Grandpa Kreng) and Yai Riem (Grandma Riem), lived together in what is now Lamphun province. They were not wealthy, but their love and dedication to their son, Ta Mong, were renowned throughout the village.

Knowing their son deserved a good future, they arranged a marriage between him and a woman from a respected family on Koh Samui. To formalize this union, they journeyed by boat to Samui to ask for the girl’s hand in marriage, bringing gifts and hope for their family’s future. However, fate was unkind; midway through the journey, a fierce storm capsized their boat off Lamai Beach. Unable to survive, Ta Kreng and Yai Riem turned to the heavens, asking for their intentions and love to be immortalized so their reputations would remain pure and their devotion remembered. According to the legend, the next morning, the people of Samui discovered the two stones on the beach, standing side by side, forever together.

Symbolism and Culture

Local people interpret Hin Ta and Hin Yai as a powerful symbol of fidelity, hope, and genuine love, traits celebrated throughout Thai culture. For the superstitious, the fertility symbolism of the rocks makes them a site where some couples come to pray for marriage or children. The story is especially cherished because it mixes humor, romance, and the respect for family that defines much of Lanna (and broader Thai) tradition.

The Science Behind the Stones

While the legend gives a heartfelt reason for these curiosities, geologists have explained that the rocks are the result of millions of years of granite erosion, shaped by salt, waves, and tropical storms. It’s a charming example of how nature and culture collide, natural processes giving rise to forms that spark the imagination and become woven into the folklore of a whole region.

Regardless of the science, it’s really the story that lingers, part of why visitors are drawn to these “naughty” rocks, camera in hand, ready to toast to love and laughter.

Visiting Hin Ta & Hin Yai: Tips and Local Etiquette

How to get there

The rocks are found at the southern tip of Lamai Beach, about 20 minutes by car from Chaweng. The best way to experience them is as part of a Koh Samui day tour, or with your own rental motorbike or car. Public songthaews (shared taxis) do pass by this area if you want a budget-friendly option.

What to expect

• There’s a small cluster of souvenir shops and vendors selling coconut ice cream next to the rocks, great for a quick refreshment on a hot day.
• The area is free to enter, but parking can fill up quickly during high season (December–April).
• Plan to come early morning or late afternoon for cooler weather and less crowding.
• Use respectful language (remember, these stones are cheeky in appearance but meaningful to locals).
• Don’t forget your camera, the coastline here is stunning.

Local treats and traditions

When in the area, look for Kalamae, a sweet coconut taffy famous in Samui. Vendors around Hin Ta Hin Yai often offer this sticky treat as a local specialty. Trying new sweets is a huge part of Thai travel, and don’t be shy to ask the vendors about the legend while you taste.
