The story: Lijiang Old Town was founded in the late Song dynasty (13th century) and built without walls β a Naxi tradition, since a city with walls 'traps' good fortune. Its cobblestone lanes follow the canals of the Jade River, which flows through every street (the Naxi used to wash the town's stone by opening sluice gates). It became a UNESCO World Heritage Site in 1997, the first old town in China to be listed.
Why it's a must-see: There's no other old town quite like it: waterways threading every lane, stone bridges every few dozen meters, and a layout designed to be walked without ever feeling lost. It's also genuinely alive β residents still live and trade here, and the surrounding Naxi courtyards (with their 'three rooms one screen wall' architecture) are beautiful.
π‘ Kat's tip: Wander off the main tourist lanes (Sifang Street) into the quieter northern alleys, especially at 7am when the town is empty and the canals sing. Entry is free, but there's a 50 RMB 'maintenance fee' collected at some gates β it's included if you stay in a licensed guesthouse.
