At the very border with Burma sits a long-established riverside Karen Long Neck settlement. There are numerous rapids and gorges. The rivers teem with exotic birdlife, kingfishers, egrets, and duck, shimmering insects and abundant butterflies. Wild animals, buffalo and cattle come to drink at the banks and native Tribesmen fish the teaming waters using traditional methods.

The Green Season, October and November are the best months for world class white water rafting and kayaking on the Lang below Kanlaya’s, the Khong and Pai rivers. After that the waters are placid and by Christmas the Lang is shallow. Even in the dry season the rivers offer a unique route into the wilderness and jungle. For the adventurous there are two-day expeditions down the Khong and into the Pai, overnighting in jungle riverside camps far from the nearest human civilization, disembarking in Mae Hong Son town.
