Chiang Khan Walking Street (Loei)

If you want to wear a winter jacket in Thailand, go to Chiang Khan. The famous wooden walking street along the Mekong River turns into a cozy, nostalgic festival. There are no massive stages here; instead, you get acoustic folk music, local crafts, and people releasing floating lanterns (krathongs) onto the river. It’s incredibly popular with Thai couples seeking a romantic, slow-life New Year.
