A morning mist lifts off limestone towers as the boat slips away from Beo Wharf — nets and floating houses recede, and the emerald of Lan Ha Bay opens like a road carved through stone. Passengers spread across the deck, cameras at the ready, while the guide points out the boat’s route toward the cored karsts and the sheltered coves of the Dark Cave and Ba Trai Dao.
