More ways to explore the area's outdoor wonders
The bamboo poles of a fishing boat cut through glassy water as the Mercury Cruise slips between karst towers — limestone cliffs rising like old shipwrecks from green-blue sea. Onboard, teak decks and shaded lounges give way to the wide windows of a luxury cabin; outside, the islands rearrange themselves with every hour, daring you to photograph them from new angles.
