The Gibbon Experience is one of the most unusual things to do in Laos: you sleep in treehouses high in the forest canopy of the Bokeo Nature Reserve and travel between them on a network of ziplines strung through the jungle. The experience lasts two or three nights and includes guided walks with the chance of spotting black-crested gibbons, one of the rarest primates in the world.
The treehouses are simple but genuinely dramatic — built at canopy height, with views over the forest that stretch for kilometres. The ziplines are long and fast; no experience is required, but a head for heights helps. Booking is essential and must be done well in advance, especially during the November–April high season. The Gibbon Experience office is in Huay Xai town; book directly with them rather than through third parties.
