Kok River, is one of the most scenic attractions in Chiang Rai. It runs from Thathon in northern Chiang Mai to Chiang Rai City and then flows on to meet the Maekhong River at Chiang Khong. From Baan Thathon boats, rafts and treks leave daily venturing into the surrounding mountains where the jungle dips into the river's cool waters.

A long-tailed boat can be hired to ferry visitors up and down the river. Stops can be made at Akha or Iko, Lisu and Karen hill tribe villages. Alternatively stops can be made at the Buddha cave, a temple within a cavern; an elephant camp, for trekking; a hot spring; and a riverside Lahu village. Trips range from 300 bahts to 700 bahts ($7-$16), depending on the number of stops made. The ferry pier is beyond the bridge across from the Dusit Island Resort.
