The 3-day, 2-night journey to 2 special natural heritage regions recognized by Unesco is an unforgettable journey for every visitor when coming to Vietnam. Cruise along the green canal through a thousand-year-old limestone cave system, visit the temple with the largest bronze Buddha statue in Southeast Asia, or float on a luxury yacht, practice Thai chi in the morning light or sip a glass of wine when the sunset falls on the surface of the heritage bay among thousands of rocky islands.
