For several hundred miles, the Mekong river acts as the border between Laos and Thailand. For most of this part of my Mekong trip, I stayed on the Lao side of the border, but for a few days at the end of June I crossed over to Thailand, partly to get a new Lao visa, and partly just to see the other side of the river. Although there is a ferry service connecting the two sides, this now seems to be reserved for Lao and Thai nationals only. Everyone else has to travel by road, across one of the impressive new Friendship Bridges spanning the river. From Tha Khaek in southern Laos, I took the bus (along with a boisterous extended Vietnamese family) to Nakhon Phanom in Thailand, where I stayed for a few days before travelling downriver to Mukdahan for a night, from where I crossed back into Laos via a different bridge, travelling on to Savannakhet. I’ve written before about how countries along the Mekong gradually merge into one another in border regions, and these riverside towns were another example of that, although the Thai side was noticeably busier and more prosperous. These pictures were all taken in Tha Khaek, Nakhon Phanom and Mukdahan.
