Welcome to The Southern Islands
That's not to say that all small-scale development is fine. Koh Rong, in particular, has changed dramatically in the past couple of years due to unchecked construction in the Koh Tuch area. But for the most part, Cambodia's islands are still paradise the way you imagined it: endless crescents of powdered-sugary-soft sand, hammocks swaying in the breeze, photogenic fishing villages on stilts, technicolour sunsets and the patter of raindrops on thatch as you slumber. It seems too good to last, so enjoy it while it does.
