The original inhabitants of Koh Kood were Thais and Cambodians who fled to the Thai territory when the French took over the city of Padjantakiri in 1904. The oldest community is Klong Mad Village whose residents still make a living out of planting rubber trees, cultivation of coconuts and basic fisheries. But the biggest community on Koh Kood is Ao Yai Village, a harbor where many fishing boats seek refuge during rough weather. Koh Kood (Koh Kud) has an essential infrastructure which includes a hospital, couple of schools, a police station, electricity (mainly for state-run facilities), water and telephone system. Fuel and solar energy are the main source of power on the island.
Ridged plains have given rise to many inland brooks, streams and waterfalls. The Klong Chao Waterfall is probably the most impressive with it’s height and spread. With three tiers it allows visitors to swim and bathe in the waters all year around. It was visited by King Rama VI in 1911 and was given the royal name ‘Anamkok Waterfall’ in commemoration to Ong Chiang Lue, a Vietnamese king taking refuge in the Kingdom of Thailand during the reign of King Rama I in the late 18th century.
