White sand beaches, palm trees, turquoise waters and amazing food. Thailand fully lives up to the hype. We spent a week on the island of Koh Samui for our friend's amazing destination wedding. The island really is the perfect size. Not too big, not too small, and packed perfectly with adventures. But, if you're looking for pristine, untouched Thailand you'll have to venture off Koh Samui and into the Mu Ko Ang Thong National Marine Park.
