Cachoeiras do Prata is a full-day waterfall outing from Cavalcante, not a quick roadside swim. The complex strings together clear pools and falls in the Chapada dos Veadeiros landscape, with a long dirt-road approach and enough walking to make the swims feel earned.
Go with a local guide or very current directions, because access routes and land arrangements can change. It is best for travelers who want a more rugged day than Santa Bárbara and are comfortable with heat, distance, and rough roads.
