I was in Nong Khai last week. Luckily I returned just before it was hit by heavy flooding. It’s a pleasant little town, particularly at this time of year when it has a sleepy low season feel about it.  The town sits in the northern reaches of Issan and you can enjoy lazy evenings dining beside the Mekong River on floating restaurants and, if you wish, cross into neighbouring Laos via the Friendship Bridge. The area is known for great sunsets and the bridge is a good spot to capture them.
