Cruise the Upper Mekong River between the historic ancient capital of Luang Prabang, a World Heritage site, and Houei Xay, located on the border at the northernmost point of Thailand, near to the infamous Golden Triangle.

The Sepik River is one of two vast tropical river systems in Papua New Guinea that meander through the densely forested lowlands of the world's second largest - and the world's tallest - island. Along the banks of the river and its many tributaries live sparsely scattered, remote villages scarcely contacted by the outside world, where people live a lifestyle that has changed little for thousands of years.

If you have never visited Cambodia before and are limited on time, the highlights not to miss are the ancient, UNESCO World Heritage-listed temples of Angkor, including Angkor Wat, and the Mekong riverside capital of Phnom Penh, once regarded as the Venice of old French Indochina.

Already renowned for its inspiring ancient temples rising out of the jungle, Cambodia is also rich in exotic wildlife. In particular, birdwatching enthusiasts will find much to twitch about with a number of key sites to enjoy their passion.
