The Gibbon Express (2d-1n)
The tour starts after a one-hour drive from Houayxay. Access walk is steep for over an hour and is thus recommended for trekkers in good physical shape aged from 12 to 50 years old. A series of very long ziplines flies you from mountain to mountain to the heart of the Nam Kan National Park and to the most giant tree to be found today in the Lao PDR. However, only one gibbon family lives in that area so your chances to meet gibbons are low in this 'airborne' program featuring more zip lines and less wildlife.
