Audio Guide of Grandfather and Grandmother Rocks

Hin Ta and Hin Yai are open 24 hours a day, every day of the year, as they are natural outdoor rock formations. You can get there by taxi, songthaew, or by renting a motorbike from Lamai Beach (about 10–15 minutes); parking is free near the viewpoint. For detailed directions, see Google Maps.

The visit is completely free, with no entrance fees or tickets required. You will only pay for transportation to get there, such as a taxi for around 200–300 THB from Chaweng.

It is recommended to allow 30 to 45 minutes to enjoy the rocks, take photos, and explore the nearby viewpoint. If you combine it with a walk along the beach, it may stretch to about 1 hour.

These rock formations, known as 'Grandfather' (Hin Ta) and 'Grandmother' (Hin Yai) because of their genital shape, come from a local Thai legend about an impossible love between Mae Nang and her suitor, who were turned to stone by grief. They represent fertility and are a folkloric symbol of Ko Samui. More details at Tourism Authority of Thailand.

The best time of day is at sunrise or sunset for stunning photos with good light and fewer crowds. Visit during the dry season from December to February to avoid rain; avoid midday because of the intense heat.

Access involves steep steps and uneven rocky ground, so it is not recommended for wheelchairs or serious mobility issues. People with moderate mobility may manage it with caution, but consider alternatives such as distant viewpoints.

Nearby you will find Lamai Beach (5 minutes away for relaxing and food), Lamai Viewpoint (panoramic views), and the Secret Buddha Garden (20 minutes away by motorbike). You can combine them into a coastal day trip.

Bring sunscreen, water, and comfortable shoes because the terrain can be slippery; go early to avoid crowds and reckless motorbikes. Respect the site by not climbing on the rocks, and try local food at the nearby stalls for an authentic experience.
