Koh Kood is located at the very end of the Thai eastern maritime territory bordering Cambodia.
Covering 105 square kilometers, it is the second biggest island of the province of Trad, after Koh Chang. Due to past political problems in Cambodia, it was unaccessible for many years but it is now popular with those who seek an untouched paradise. What draws visitors, mostly locals, to come to this island is its completely pristine nature, both inland and underwater. Small mountains and ridged plains have given rise to many inland brooks, streams and waterfalls. Klong Jao Waterfall in particular is particularly spectacular. With three tiers, it brims with glittering water all year round, superb for soaking and swimming.
