I've been to Chiangkhan I went 1 year ago. It was really very nice place for relaxation and let your mind fly with local life. I went with my family. We visited old town area 're along the Khong river which you can see some old wooden shophouses and in colonial style. An some old and important temples 're in this area such as Sri Khun Muang temple, Mahathat temple and Tha Khaek temple. Walking on a small street on the bank of Khong river's also a great things to do in the early morning or late afternoon.
