Khao Phlai Dam, often referred to as the “Southern Sea Dragon,” is one of the most enchanting and well-preserved eco-tourism destinations in Nakhon Si Thammarat Province. Located along the border between Sichon and Khanom districts, the area is surrounded by lush mountains and the vast blue waters of the Gulf of Thailand. It forms part of Khlong Leng Forest Reserve, which remains rich in tropical rainforest, providing fresh air and a tranquil atmosphere throughout the year.

The area is renowned for its biodiversity, serving as a habitat for a wide variety of wildlife, from small forest creatures to rare animals such as serow, which are occasionally spotted along the rocky slopes. Birdwatchers will find this place especially rewarding, as more than 140 species of forest and seabirds inhabit the area, filling the air with natural melodies.

Along the coastline, massive granite rock formations are scattered among stretches of soft white sand, creating a dramatic and untouched natural landscape. Thong Yang Bay is a popular spot for relaxation, known for its clear seawater and peaceful ambiance—ideal for enjoying sea breezes and coastal views.

One of the most iconic highlights is the Khanom–Sichon coastal road, which winds gracefully across the hills of Khao Phlai Dam. Often praised as the most beautiful road in southern Thailand, it offers breathtaking panoramic views where the deep blue sea meets the horizon. According to local legend, the name “Phlai Dam” originates from a mythical black-tusked elephant that once transported sacred treasures to help build Phra Borommathat Chedi in ancient times. A memorial has been established to honor this legendary elephant, which remains deeply respected by local communities.

On calm mornings with favorable weather, visitors may be fortunate enough to spot pink dolphins swimming near the shoreline. These intelligent marine animals are a symbol of the area’s clean waters and healthy marine ecosystem.

Popular activities include scenic drives along the “Dragon Road,” stopping at various viewpoints for photography, and enjoying the contrast of mountains and sea. On exceptionally clear days, Koh Samui and Koh Phangan can be seen faintly in the distance. For adventure seekers, nature trails leading to the mountain summit reveal dense rainforest, ancient ferns, and small hidden waterfalls that offer refreshing moments amid nature.

Khao Phlai Dam perfectly blends the grandeur of mountains with the serenity of the sea. Whether for adventure or relaxation, this destination offers a truly rejuvenating escape filled with fresh ocean air and unspoiled natural beauty.
