The RV River Kwai, the first inland cruise ship in Thailand, is a newly built colonial style river cruiser based on designs used by the original Irrawaddy Flotilla which was founded in Burma in 1865 and by the 1920s was the largest privately owned fleet of ships in the world.

The RV River Kwai opens up an entirely new area for river tourism in Kanchanaburi province west of Bangkok. Every morning and afternoon land excursions are offered to visit attractions along the river including temples, historic sites, Khmer ruins, waterfalls, war cemeteries, hot springs, the bridge on the River Kwai, and local attractions, etc.
