About Hin Khi Sua Lighthouse

The Hin Khi Sua lighthouse is a 7-meter-tall cylindrical tower situated on a rocky reef, about 5 kilometers northeast of the Laem Pu Chau lighthouse.

The site is accessible by boat from the nearest port of Sattahip, which is 6 kilometers away. Although the location is open to visitors, the tower itself is closed.
