You push off from Beo Harbor as the harbor light shrinks behind you, limestone towers rising like unfinished sculptures from a glassy sea. The boat eases into Lan Ha Bay, where karst cliffs funnel wind and whisper through narrow channels; paddles cut the water in steady, polite rhythms as you thread into Dark Cave and pop out beneath a sky full of gulls.
