Rio Apiaú is a river flowing through the state of Roraima in northern Brazil, situated in one of the most biodiverse regions of the Amazon basin. The river runs near Boa Vista, the state capital, and winds through a landscape that transitions between savanna-like cerrado and dense Amazonian forest. This remote and largely undeveloped waterway offers anglers access to the rich aquatic biodiversity characteristic of Roraima's river systems, where the combination of tropical climate, varied habitat, and relatively low fishing pressure creates rewarding opportunities for those willing to make the journey.
