Balneário Municipal is Bonito's simple, democratic river day out. Instead of committing to one of the pricier guided excursions, you can swim in clear Formoso River water, watch fish move around you, and spend a relaxed few hours under the trees.
It is not the wildest or most spectacular Bonito experience, but that is part of the appeal. Families, locals, and travelers use it as an easy reset between caves, snorkelling trips, and longer drives into the countryside.
