Koh Nom Sao consists of two small limestone islands situated closely together in the bay of Khao Sam Roi Yot National Park. The islands' name comes from their distinctive physical appearance, resembling a pair of female breasts, establishing them as one of the best-known natural symbols in the Sam Roi Yot sea area. The islands are predominantly limestone covered with vegetation and lack beaches for landing. However, their main beauty lies in the surrounding scenery when viewed from a boat or from the Khao Daeng canal coast.

Although landing on the islands is not permitted, Koh Nom Sao is crucially important for its landscape and ecological value. The islands serve as a spectacular backdrop when viewed from Sam Phraya Beach or from the Khao Daeng viewpoint. They are particularly featured during boat tours to observe the scenery and local fishing lifestyle near the Khao Daeng canal mouth. Tour boats approach the islands to allow visitors to capture the impressive sight of the twin rock formations standing prominently in the blue sea, which often features clear, azure water.

The main activities associated with Koh Nom Sao are scenic boat trips and photography. Koh Nom Sao is part of the National Park's boat route that showcases the biodiversity and limestone mountains within the Sam Roi Yot Bay. Tourists will experience the genuine tranquility and majesty of nature, with Koh Nom Sao serving as the focal point of the vista. The best time to view the islands is in the morning, when the sunlight hits the islands and the sea is calm.

Koh Nom Sao is particularly appealing to Landscape Photographers who seek to capture unique and powerful natural elements, as the islands' shape is distinct and stands out in the sea. It also creates a romantic atmosphere for couples taking boat trips to witness the sunrise or sunset, with Koh Nom Sao forming a beautiful silhouette.

We invite everyone to take a boat trip to view Koh Nom Sao, the symbol of natural beauty in Sam Roi Yot, and let this pair of limestone islands become an unforgettable impression of your visit to Prachuap Khiri Khan.
