The mountain section of National Route 13 between Vang Vieng and Luang Prabang is one of Southeast Asia’s most dramatic highland drives, climbing from limestone karst to the 1,400 m Phoukhoune plateau before descending to the Mekong.
Heading north from Vang Vieng the road follows the Nam Song valley past karst towers before the gorges north of Kasi, where a 14 km ascent gains over 1,300 m on a narrow sealed road with back-to-back switchbacks and 20% grades. The Phoukhoune plateau opens at the top before the long, spectacular descent through forested ridges to the Mekong valley at Luang Prabang.
