Travel upriver from Bangkok on a converted rice barge to visit Ayutthaya, Thailand's former capital that was conquered by Burmese invaders in 1767. The trip encompasses over 400 relics of ancient Thai architecture, from splendid palaces to atmospheric ruins, along with scenes of Thai country life along the river bank. It's possible to go there and back in a day, but you can also spread the journey over three days, sleeping in the barge's air-conditioned cabins.
