Next to the bridge that connects the villages of Paraduça and Ervedoso, this waterfall (Linen Well Cascade) takes this particular name allegedly because, in the past, women used to wash the linen plant in that particular well or pound. The main waterfall, with about 8 meters high, is backed by other smaller falls, descending an important gap from the plateau of the Freita mountain to its end into the river Teixeira. About 2 million years ago, the hydrographic network of the Paraduça river developed a progressive slot in the granitic massif of Junqueira. The orthogonal fractures, occurring in the granitic rock, are the source of the fragility providing the progression of the river’s fluvial erosion.
The Paraduça river is a tributary of the Teixeira river and, as such, inherits the amazing biodiversity that characterizes it. In riparian forests we can see the graceful camberwell beauty butterfly and the royal fern, and in the surrounding oak forests there is frequent columbine and solomon’s seal as well as passerines, such as the tit and the bullfinch. Very rare and elusive is the pyrenean desman, protected species in need of rivers in excellent condition to survive. By the river, just below the village of Paraduça, the adernal forest develops in its entire splendor, with species such as the green olive tree, the myrtle, the narrow-leaved mock privet and the strawberry tree in its great floristic display.
Just above Cascata do Poço do Linho we have the route of Paraduça watermills which has three fully recovered mills. Inside of the watermills we see the rotating wheel taking advantage of the potential energy of the water driving the rotational movement of the grinding wheel and thus crushing the corn to produce the desired flour.
