The Canhão das Estacas is a small gorge at the Estacas River, a tributary of the Agualva stream, that passes through the Lomba village. An erosion carved an escarped valley into the rock, taking advantage of the weaknesses of the flaws in the shale. The Agualva stream, which initially runs in granite and then precipitates in the soft shales, formed on its banks one of the most beautiful forests in the region. The slope of the valleys multiplied the presence of cascades and waterfalls.
