Rafting Along the Mae Kok River : This 130-km river is well known as one of the most picturesque and clean rivers in Thailand. Rafting along the waterway is a very relaxing activity because tourists can see hilltribe villages situated along the banks. Lush jungles and mountain cliffs create scenic views and a fresh atmosphere. It takes 3 days and 2 nights to cover the 80-km distance by raft from Tha Ton of Chiang Mai to Chiang Rai town. River trips to and from Chiang Rai by long-tail boats are also organized regularly. The trip takes about 4-5 hrs.
