The Waterfall Gibbon Experience (3d-2n)
This programme takes you deeper into the National Park, with a two-to-three hour trek each day along the Nam Nga River and through a fresh-water swimming pool and a charming waterfall. One tree house gives upon the river while the other shows sunsets overlooking several valleys. To join this option, you should be in a reasonably good shape. Two groups of 8 people depart on alternate days soon after 8 am for two nights in the Bokeo reserve, swapping tree houses on the second night.
