Sleepy Nong Khiaw, 78 miles (126km) north-east of Luang Prabang, straddles the languid Nam Ou River at the bottom of a deep, forested valley. Wonderful views of the surrounding peaks are to be had from the Chinese-built bridge that connects the two sides of the village, but you’ll get a more vivid feel of the landscape by taking a guided trek along the river. Taking you up a series of low cascades via bamboo ladders and fixed ropes, the ‘100 Waterfalls’ route is a memorable soft adventure. Kayaking trips are also on offer.
