Koh Chang is a good place for a vacation. i've always gone with my family. I went there 3 month ago. Koh Chang is the most beautiful place. it has always been nutural abundance.
i've also read about coral diving in Koh Chang ,coral reefs in deep water is very beautiful. This must taken a boat out to sea . You saw the beauty of it . I did never get to see. I did never go by boat because i've always gotten seasick.
