Once again I'd travel on route 13 heading north from Vang Vieng and ending up in Luang Prabang, these roads becoming very familiar to me. Outside of Vang Vieng is incredibly beautiful with the karst landscapes and lush forestation. Past Phou Khoun on the way to LP you're driving along mountainsides swirling up and down and up and down and have access to the sights of beautiful valleys below. Just don't look too long or you'll drive off!!
Another ridiculous sign. Xishuangbanna (as you may recall from my travels last January) is in the southwest of China. Though somewhat close in relative distance, you're still pretty far away. Chinese tourism at their best.
