Salt air, teak boat timbers and the distant chop of the South China Sea usher visitors toward Hon Mun — Mun Island — where coral walls fall away into blue. The day begins at the harbor in Nha Trang; within an hour the coast shrinks and the reef appears like a living map beneath the surface, fish threading through branching corals.
