A break from the norm
An up and coming beach holiday destination only a few hour's bus trip or 40 minute flight from Bangkok. If you're tired of the same old tourist beach traps - Pattaya, Samui, Phuket, Phi-phi, Krabi etc, visit Ko Chang, the second largest island in Thailand whilst it is still relatively pristine and undeveloped.
 
There's plenty of accommodation to suit all budgets along the west coast beaches which are seldom crowded even in high season.
