This is Krabi, Thailand. Well, it's a snipped of the countless paradise islands like Phi Phi Island, Hong Bay, Ko Phi Don and others, popularized in the late '90s with millennials via Alex Garland's terrific The Beach, starring one Leo DiCaprio. It's now a hotbed for the world's gap-year students seeking an adventure in a teal-coloured ocean. I don't blame them. It doesn't get much more beautiful than this.
