Mekong River cruises in Thailand occur in the eastern portion of the country where the Mekong River forms the border with the country of Laos. In the northern part of the country, where the river turns east and flows only in Laos, is the legendary Golden Triangle where the countries of Thailand, Laos, and Myanmar (formerly Burma) meet. This extraordinarily beautiful area is home to a number of ethnic groups known as Hill Tribes as well as the beautiful cities of Chang Mai and Chang Rai (only about 40 miles from the Mekong). This is where many Thailand river cruises begin with a land excursion before embarking ship on the Mekong.
Some Mekong River cruises in Thailand continue sailing downstream through the Mekong River in Laos, into the Mekong River in Cambodia, and to the agriculturally rich Mekong Delta of Vietnam. Most of these longer cruises take place on small luxury ships offering lavishly furnished staterooms and suites, gourmet dining, and even air-conditioning. It is possible, however to take less opulent public ferries that make their way downriver, anchoring nightly in small towns and villages where the accommodation is in small guest houses and budget hotels.
Other Thailand river cruises occur on the beautiful Chao Phraya River that flows through the capital city of Bangkok in the western part of the country, and short cruises are possible on the famous River Kwai immortalized in the 1957 film Bridge on the River Kwai about the building of the Burma Railroad by Allied prisoners during World War II.
