Emerald Cruises and Tours has opened bookings for its 2026–2027 river cruise season across Vietnam, Cambodia, and Laos, with extended land tours into Japan. The programme features 17 itineraries along the Mekong River, combining small-ship cruising with cultural excursions, heritage sites, and local experiences. Company officials say demand for immersive, multi-country river cruising continues to grow among travellers seeking slower, experience-led journeys in Asia.
