A short, sinuous run threading between towering limestone karst to the dramatic Nam Ou river gorge at Nong Khiaw, one of mainland Southeast Asia’s finest mountain approaches.
From the junction at Pak Mong the paved road curves east into a landscape of sheer limestone karst, the peaks rising abruptly from paddy and Hmong villages. The driving is flowing rather than frantic, but the scenery is relentless, building to the cliff-walled gorge of the Nam Ou where the road drops into Nong Khiaw beneath some of the most photographed mountains in Laos.
