It was a nice 1100km-Trip from Roi Et - route and roads you can see in the first picture. The main points ChiangKhan - Erawan-Cave - Nong Khai are in red letters, the other letters show the highway-numbers. First day we drove from Roi Et to Chiang Khan. It is a nice small town with beautiful old wooden houses and many guesthouses. Most interesting times are the evening with night market and good food and the early morning ( about 6am ) when many people are sitting in the street waiting for the monks.
