Three days of emerald water, karst towers and small-village life: this overnight cruise from Hanoi pairs sea-based activities — kayaking, swimming, cave visits — with quiet time on deck. Read on for what to expect and how to prepare.

Mist rises off an emerald sea as the cruise slips past a forest of limestone towers — some bare rock, some crowned with jungle. On the first afternoon the boat threads into Lan Ha Bay, where cliffs lean toward the water and fishermen tend floating farms; the soundscape is gulls, lapping water, and a distant engine. Morning light brings Tai Chi on the sun deck and a slow shift of islands that seem to rearrange themselves with each mile.
