Set amidst jagged limestone cliffs on the banks of the Ou River, Nong Khiaw is a picturesque town where it is easy to get lost for a few days. Go hiking or biking along verdant jungle trails to outlying hill tribe villages where locals still dress in vibrant traditional clothing; float down the river on a bamboo raft to enjoy gorgeous views of the lush, mountainous surrounds; or take a short (2km) trek to the Pha Tok Caves, which gave refuge to Pathet Lao soldiers during the Second Indochina War. After a day out, indulge yourself with a steam bath or massage at one of the local spas.
