Take an unforgettable adventure through two of the most colourful yet contrasting cultures in South East Asia. Starting off in Vietnam, cruise through dramatic karst scenery on a boat tour of Ha Long Bay, step back into the world of the country's last emperors in Hue, soak up the old-world charm of Hoi An and be awed by the endless energy of Ho Chi Minh City. In Cambodia, discover the country's fascinating history and culture in Phnom Penh's heaving streets and in the awe-inspiring temples of Angkor. This is a journey that draws you away from the crowds and into heart and soul of this captivating region, and its equally enchanting people.
