The only way to visite Bokeo Nature Reserve is with the Gibbon Experience. Idid it in october, and it's so much fun. A little bit scary the first times but once you did it, you don't want to stop. You sleep in threehouses, they are 40m above the ground, and to go in and out you have to zip. You can't travel around in Laos, without visiting the Gibbon Experience. It's 3 days a lot of fun, you can enjoy the Forest while you're zipping. It's such a beautifull sight!! Also when you're in Thailand, Chiang Kong, you can cross the border by boat and do the Gibbon Experience. The office is in Ban Houayxay, Laos. It's better to reserve it a few weeks before, because there's so much people who want to do this. You don't know what you're missing!!!
