Good day hike from Nong Kiau village
Went for a 4 hour walk (you can hire a mountain bike as well) to visit some Kamu villages. The Kamu are one of the hill tribe people in Laos who are originally from china but have populated Laos for hundreds of years. They look quite different from the Laos people and generally have more facial hair ( the men i mean, I'm not taking a dig at kamu women there).
There are some great views of the Ou river north of Nong Kiau, lots of spiders, some jungle water fountains (basically a bamboo pipe stuck in the side of a hill that taps an underground steam, doesn't get much more fresh than that), and some cool fishing techniques on display- a small bamboo dam block the river flow and directs it through two small channels where the locals have set up nets to catch fish- it's automated fishing! There are four villages before the road ends, takes about 7 hours return if your walking, take sunscreen, you can fill your water bottle at the bamboo tap.
