A deluxe, live on board cruise across South East Asia's largest freshwater lake, the Tonle Sap, is an ideal way to explore hidden parts of Cambodia at a deliciously relaxed pace while travelling between the must-see destinations of Angkor Wat and Phnom Penh.

For those who do not have time for an extended sailing cruise, or whose taste for being on a boat extends only to a few days, a short sailing cruise to the Komodo National Park is a must do component of any Indonesia visit.

With more than a thousand limestone peaks rising out of its crystalline, emerald waters, Halong Bay is is rightly viewed as one of the natural wonders of Vietnam, and is one of the country's five UNESCO World Heritage sites. Lesser known, and therefore less touristed are the equally stunning Lan Ha and Bai Tu Long Bays.

Cambodia has some spectacular opportunities for the more adventurous, active visitor. The mountainous northeast provinces of Ratanakiri and Mondulkiri are still largely forested and home to a number of tribal minority peoples, while the Cardamom Mountains of the southeast are considered to host the largest remaining contiguous block of rainforest on mainland South East Asia.
