Klong Son beach (or Had Klong Son) is located on the north of Koh Chang. Nice bay at the very top of the island. Pure white sand stretch of beach, shaded with coconut trees. Klong Son gets very low numbers of visitors with the bulk of the backpackers and tourists alike speeding south enroute to Koh Chang's finer and more popular stretches of sand.
There are 2 beaches in Klong Son, the long Chang Noi Beach that extends over the whole bay and the small Halfmoon Beach that faces the mainland. In the north the the two beaches are close together. In the south a river splits the Chang Noi Beach into two parts.
At low tide the sea draws far back as at almost all other beaches on Koh Chang.
Klong Son is popular with the fishermen as a port, since it is quite well protected against the violent winds during monsoon. The village Baan Klong Son is sprawled across a large area.
The original section, located directly on the bay, is partly built on stakes in the sea and is mainly inhabited by fishermen.
The newer part of the village is situated by the road and many houses are built along the river and into the southeast valley. Beside Wat Klong Son (temple) and a school, there is also a clinic in the village. It is situated 400 meters off the village intersection towards the bay.
There are many small shops, some restaurants and an air-conditioned supermarket located in the village. Approximately 4 kilometers southeast the Nam Yom Waterfall is situated.
