Fodor's Expert Review Parque Ecológico Rio Formoso

The approximately 1½-hour rafting trip on the Rio Formoso takes you through clear waters and some rapids while you observe the fish and the birds of the Pantanal. You might also see and hear bands of macaco-prego (capuchin monkeys), the region's largest primates. The tour ends at Ilha do Padre (Priest's Island), where there's a complex of rapids emerging through thick riverine vegetation. There's a snack bar where you can relax after the tour. To best appreciate this attraction, make sure there hasn't been any rain in the previous days—the river gets quite muddy. Horseback riding is also available.
