Thais often stop in the dusty town of Phibun Mangsahan (พิบูลมังสาหาร) to see a set of rapids called Kaeng Sapheu, just downstream of the Mun River bridge. The rocky islets make 'Python Rapids' rise between February and May, but the shady park here is a pleasant stop year-round.
Villages past the bridge as you drive toward Khong Jiam are famed for making iron and brass gongs, both for temples and classical Thai-music ensembles. You can watch the gong-makers hammering the flat metal discs and tempering them in rustic fires at many roadside workshops. People make drums, bells and cymbals here, too.
