Koh Samui Airport is a unique and highly successful experiment in building an airport that is kind to both the cultural and natural environments of a tropical island resort. Flying in, you get brief glimpses of outlying islands, streaks of surf, the wakes of small fishing craft sketched across the calm aquamarine sea. Smudges of coral reef dapple the water as you come in closer still. Then the coast of Samui appears. Two hundred and fifty kilometres of tropical hideaway scalloped by dozens of bays rimmed in white sand, carpeted in lush textures of forested hill and coconut grove, Koh Samui is the centrepiece in a group of 80 other islands set in the Gulf of Thailand. Bangkok Airways operate up to 15, eighty minute, flights per day on the Bangkok to Samui route and 4, ninety minute, flights per week on the new Samui to Singapore route.
