A longtail boat slips through turquoise water and the limestone walls close in until the sea becomes an emerald room — this is Hong’s hidden lagoon. You step from the wooden deck into shallow, translucent water and the sound of the motor falls away, replaced by gull calls and the soft scrape of sand underfoot.
