The old wooden-house core of town and the most important place to understand Chiang Khan's atmosphere, food, and heritage reuse.
The official Loei tourism brochure is right to frame the street as Chiang Khan's heart rather than as a side attraction. The street matters because it still connects old architecture, everyday commerce, guesthouses, snacks, and river life in one walkable strip.
Current Info: Walking Street is most useful from late afternoon onward, and the official Loei guide notes it opens from 4pm daily.
