Cruises on this river mostly take place from October to April to avoid the monsoon season. In those months, you can expect the weather to be hot and dry. A number of big cruise operators offer cruises on the Mekong, including Vantage Deluxe World Travel, Uniworld and Panda. Itineraries for cruising to the Mekong are subject to change due to the fluctuating water levels on the river.
The vast size of the Mekong means that the majority of cruises on this river last at least two weeks and very often longer. Given that the majority of passengers on these cruises have travelled a considerable distance, this is an advantage, as you can make the most of your stay in this fascinating region.
